Is there a better irrigation plan for your landscape?

Drip irrigation has some real advantages over traditional automatic sprinkler systems when it comes to saving water and money:

Irrigation Comparison Table 1

Learn how to install drip as part of your own sprinkler system at the Drip Irrigation and Rainwater Harvesting Workshop Saturday, April 6.

Local drip irrigation and rainwater harvesting specialists will provide both classroom and hands-on instruction. You’ll learn how to convert an existing sprinkler head to drip as well as how to install drip irrigation from an outdoor hose bib. With drip irrigation in place, you’ll be “efficiently” prepared for summer watering.

Our wet weather means that rain barrels are another great water conserving tool. At the workshop you will see how easy it is to capture rainwater  in your backyard, and will be able to purchase a rain barrel at a discounted price through one of our workshop sponsors, The Woodlands G.R.E.E.N.

Space for this popular seminar is very limited and registration is required. For more information or to register, see the calendar page.

Plant for pollinators this spring!

At first glance, a pollinator garden may look like any other pretty flower garden. But for a garden to be a haven for native bees, butterflies, and moths, it needs to meet their needs for all life stages. And the most important ingredient are plants rich in nectar and pollen to feed adult pollinators and host plants specific to butterfly species. Here are simple guidelines for creating a pollinator garden that will reward you with three seasons of garden visitors and help protect these vulnerable insects.

Choose a sunny spot.

Most blooming plants require sun. Four hours of sun is ideal, but a minimum of two to three hours will work too. Some great nectar and pollen plants thrive in part shade (two hours of sun with dappled shade the rest of the day).

Plant natives.

Native plants support more than 29 times the number of insect species than non-native plants. Aim for at least 70% of native plants in your garden. (Print the PDF for recommended plant list.)

Plant host plants.

Host plants are where the female butterfly will lay her eggs and her young caterpillars will feed. Some butterfly species—like the monarch and some swallowtails—only have one host plant. It is vital, therefore, to include some of these plants to support these species. Most of our host plants are native, but some are non-natives well adapted to our area. By including these host plants, you’ll welcome more diversity into your garden. (Print the PDF at the bottom for recommended plant list.)

Plant variety.

Adult bees and butterflies like some variety in their diet, just like us. By including different varieties of plants, your garden will attract a diverse assortment of pollinators.

Plant for three seasons.

Pollinators that overwinter in our area start emerging as the weather warms, and that could be late February to early March. As the weather turns cool, bees and butterflies go into hiding. As a general rule, they can’t fly when temperatures fall to 55 degrees. Bumblebees and some solitary bees will hibernate underground; other solitary bees will hibernate in nests they create in rock crevices and dead wood tunnels . Honey bees don’t hibernate, but buzz all winter keeping the hive warm—only the queen hibernates.  The monarch butterfly is the only migrating butterfly in North America and usually leaves its overwintering site in central Mexico in March, returning in November. You can track their migration each season at journeynorth.org.

With pollinators active and needing food spring through fall, it’s important that your garden provide blooms each season. (Print the PDF at the bottom for recommended plant list.)

Plant in dense color blocks.

Avoid planting different plant varieties singly. Go bold! Group a minimum of five to seven of the same plant to create large swaths of color in your garden. This helps pollinators find them. A dense planting has another advantage. When host plants especially, are planted densely, the young caterpillars have a better chance of survival by hiding from predators.

Include a puddle.

If there’s a low area that holds water after a rain in or near your pollinator garden, leave it! These “puddling” areas are great for providing certain butterfly species (like male common buckeyes) with necessary minerals and nutrients. You can create your own puddle by filling a shallow pan or plate with soil, some rocks, and pieces of a kitchen sponge and keeping it wet.

puddler

A simple butterfly “puddler” is easy to add to a garden.

Provide shelter.

Shelter can take various forms, from a nearby fence or trellis, dense shrubbery, or a man-made bee house for solitary bees. It can also be as simple as leaving a pile of fallen leaves and pine needles in a nearby spot. Shelter provides safe places for caterpillars to pupate, and for overwintering pollinators.

Use no pesticides.

In your garden or near it. Period.

Important note about tropical milkweed

If you already have tropical milkweed in your garden, be sure to cut it to four to six inches of the ground every October to prevent the spread of OE and interference with normal migratory behavior. Consider planting native varieties of milkweed. Learn more about OE and tropical milkweed, and native milkweed species for our area in our recent blog post.

 

 

 

In celebration of trees

It’s undeniable. There seems to be a universal human response to the majesty of trees. Trees do us a lot of good and not all their benefits are visible by the eye. These benefits are often grouped by their social, environmental, and economic qualities.

(Be sure to see the upcoming Township events that pay tribute to trees listed below.)

tree-3822149

Social benefits

One might say that trees help make us happier. They provide a sense of place and when we are in their presence, we feel serene and peaceful. Trees’ calming effects extend to the workplace, where trees can reduce worker stress. It’s also been cited that trees can decrease recovery time after surgery or illness and reduce crime in urban communities. A large, mature tree imparts a sense of majesty, strength, and even awe. This and their capacity for a long life may be why they are so often planted as living memorials to those we love and have lost.

The oldest verified flowering tree is a 2,293 year-old Sri Maha Bodhi Sacred Fig. It is also the oldest human-planted tree, known to be planted in 288 BC at Anuradhapura, Sri Lanka.

People are drawn to shaded parks, pathways, and sidewalks, which in turn encourages social interaction and enhances a sense of community.

Environmental benefits

Trees improve the environment by moderating our climate from sun, wind, and rain. Sun is absorbed or deflected by leaves and the larger the tree, the greater its cooling effect. In urban environments, trees moderate the heating effect caused by pavement and buildings. Compact foliage and dense tree plantings provide an effective windbreak. Rain and stormwater runoff is not only slowed by trees, but is reduced by the water trees take up by their roots and store.

Improved air quality is another great benefit—leaves filter the air we breathe by removing particulates and pollutants (such as ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and lead) and replace them with oxygen. They absorb the greenhouse gas carbon dioxide through photosynthesis. Trees are natural air conditioners that can lower temperatures 6 to 8 degrees by evaporating water through their leaves. Their roots stabilize soil and prevent erosion, and improve water quality by filtering rainwater.

Trees can block and absorb sound, reducing noise pollution by as much as 40%.

Finally, trees provide important food and shelter for urban wildlife, including birds, pollinators, and small animals.

Economic benefits

Although determining a “value” of a tree can be very difficult, trees increase in value as they grow. The value of trees is also evident in home sales: homes landscaped with trees sell more quickly and are worth 5% to 15% more than homes without trees. When trees are planted strategically to shade a home, air conditioning costs are lower. And when they form a windbreak they can reduce heating costs in winter.

Native trees

plum-blossom-6855_1920

The native Mexican Plum, Prunus mexicana, has a spectacular spring display that is a feast for the eyes and pollinators as well.

There is a wealth of native trees to use for landscapes in our area. The benefits of native trees are many and can include colorful spring blooms, fall color, or food and nectar for wildlife. Natives are well-adapted to our weather conditions and soil, and once established, require no supplemental water (except for times of extreme drought).

View and print the list of Trees Suitable for The Woodlands. This list is far from exhaustive, but meant to provide a good sampling of those that can be found at local nurseries and provide special benefits.

Insect and Disease Problems

Irrigation can’t replace rain

You’ve seen it. The luminous post-shower greenness of a lawn; the sudden growth spurt of a plant that didn’t seem to be doing much at all; or the effervescence of new blooms on an otherwise sleepy plant. Why are these effects so evident after a good rain and absent with irrigation?

What’s the magic of rain? It’s all about what it has that tap water doesn’t,  and what it doesn’t have that tap water does.  And this all boils down to chemistry.

Rain water is free of minerals

good elements

Rainwater lacks the minerals usually found in irrigation water. In The Woodlands, the water that flows through an outside spigot is the same as what flows from the kitchen faucet—that is, treated water suitable for consumption. This is of course, what you want for water use in the home, but your landscape can actually suffer for it when used in excess.

Chlorine and fluoride are the first plant-offending additives in treated water. Chlorine is a necessary disinfectant and fluoride helps to prevent tooth decay.  But nearly all plants are susceptible to chlorine toxicity and many are subject to fluoride toxicity as well—especially common house plants.

Another chemical component to tap water is sodium, which can help remedy the pipe-corroding effects of calcium and magnesium, also present. When a white sediment is present on the outside of containers or on the leaves of plants, it’s evidence of calcium and magnesium. Sodium, like chlorine, is toxic to plants.

Rainwater has the right stuff

good elements

Oxygen, nitrogen, and carbon dioxide. Rain highly saturated in oxygen goes right to the roots that take up this vital element. Nitrogen is what makes your lawn and plants seem to glow green after a good rain. Air is 78% nitrogen and this element in its nitrate and ammonium forms comes down in rain and is immediately absorbed by plants through their roots and leaves.

Carbon dioxide is also delivered to plants with rain. When carbon dioxide combines with other minerals in the air, it gives rainwater an acidic pH. Acidic rainwater (and we’re not talking about “acid rain” which has excessive pollutants mostly an issue in the Northeast) helps the soil release essential micronutrients such as zinc, manganese, copper, and iron that are vital to plant growth.

rose-2658659

Something can be said about the physical properties of rain too.

Rain penetrates the soil better than irrigation. Raindrops fall at about 20 mph while irrigation droplets fall at about 5 mph. And rain falls uniformly. Both properties help water reach plants’ roots. And they do something else: they help leach salts away from the root zone of a plant where they may have accumulated over time through irrigation. This cleansing effect can have a pronounced effect on new plant growth.

The cleansing effect of rain extends to the entire surface of a plant as well. We can see how foliage glows after a rain washes away mineral deposits, dust and pollutants from leaves. This is a boon to photosynthesis. Photosynthesis is much more efficient when light reaches a plant’s leaves unobstructed by grit and grime.

Harvest it

The benefits of rain water over tap water used for irrigation might even motivate a person to harvest rainwater. So often, rainwater harvesting is presented only as a method for conserving water. Yet it’s more than that. By storing up rain water, you’re also creating a supply of high quality water that your plants crave.

A Drip Irrigation and Rainwater Harvesting class will be offered free by the Township later this spring.

OE and tropical milkweed

The relative virtues and problems associated with tropical milkweed, Asclepias curassavica, continue to be a hot topic within the monarch conservation community, but the disparity between the two is becoming more and more clear. Scientific research suggests that its problems, namely its link to the spread of the Ophryocystis elektroscirrha (OE) disease, far out-weigh its virtues. In fact, it’s those very virtues—availability, adaptability, and long bloom season—that multiply its negative effects relative to the health and sustainability of the monarch butterfly species.

What is OE?

OE is a protozoan parasite that infects butterflies that host on milkweed. Its life cycle starts as a microscopic spore that breaks open when ingested by a caterpillar. Within the caterpillar, it grows and multiplies. Because a parasite depends on its host for its own life, OE rarely kills the caterpillar.

scales and spores

OE spores are only visible under a microscope.

But the disease affects the development of the adult butterfly while pupating, and adults emerge weak and often with crippled wings. While many monarchs may carry OE as spores attached to its wings and thorax, the size of the spore-carrying population and the heavy level of spores within that population in the Gulf Coast region—especially Texas and Florida—is cause for alarm. Visit Project Monarch Health for more about OE.

oemonarchemergetwo6

An adult butterfly with OE has no chance of survival when wings are malformed.

Recent studies corroborate earlier studies and tighten the link between tropical milkweed and an increase of OE. Gardening to help conserve monarchs requires an understanding of the risks associated with tropical milkweed as well as the steps to take to minimize its ill effects.

The introduction of tropical milkweed in the U.S.

Monarch enthusiasts with the best intentions were thrilled when local nurseries began to offer tropical milkweed for sale and embraced the Mexican native with gusto. It didn’t take long to discover that aside from being very easy to grow, monarch butterflies love this variety of milkweed. It seemed that a solution was in hand to help restore milkweed habitat for the Eastern migratory monarch population. As a result, tropical milkweed has been well established in parts the southern states—especially southeast Texas and southern Florida.

Then research began to emerge that showed an increase in monarch disease caused by OE was linked to tropical milkweed grown in the southern states.

What the research shows is particularly troubling for the monarch migration that passes through Texas gardens to feed and breed.

The effects of tropical milkweed

Research by Karen Oberhauser, Dara Satterfield, and others has and continues to demonstrate that OE in monarchs increases where tropical milkweed flourishes. (See links to studies at the end of this blog.)

What’s been determined is that the proliferation of tropical milkweed (in the southeastern parts of Texas and south Florida in particular), coupled with its near year-round foliage and flower production does two things:

It interferes with the monarch’s migratory cycle. Tropical milkweed encourages them to linger in the southern states and continue breeding and laying eggs, “trapping” them here where they cannot survive temperatures that drop toward the freezing mark. Possibly more important is the effect of milder winters. Given a non-stop supply of milkweed, interference with normal migratory behavior produces populations of monarchs that overwinter in Texas and Florida instead of completing their migration to the oyamel fir tree forests of central Mexico.

Monarchs who stay in the southern states for the winter are five to nine times more likely to be infected with OE than migrating butterflies.

It significantly increases the rate monarchs are infected by the debilitating OE protozoan pathogen. If mild winters don’t produce a freeze, infected milkweed continues to thrive, not dying back like native milkweed species. This means infected plants persist. Infected plants in Texas are especially harmful because they sit in the gateway for the spring and fall monarch migrations.

Migrant butterflies at sites with overwintering residents were 13 times more likely to have infections compared to migrant populations that don’t come in contact with residents.

Adult monarchs migrating from Mexico in the spring that visit infected plants pick up hundreds of OE spores and carry them to other plants—increasing the number of infected plants and as a result butterflies, exponentially.

What to do?

If there’s any good news in this it could be that originally, most of the tropical milkweed planted was done so in gardens. By definition, gardens are tended. Gardeners should consider taking one of two actions.

Replace tropical milkweed with native species. While native varieties are more challenging to start, the effort would help minimize the spread of OE. Try these native species:

  • Asclepias incarnate, Swamp milkweed
  • Asclepias perennis, Aquatic milkweed
  • Asclepias tuberosa, Butterflyweed
  • Asclepias verticillata, Whorled Milkweed
  • Asclepias viridi, Green milkweed

Or, be diligent about cutting it back every winter. Cut tropical milkweed plants to within four to six inches of the ground each October.

If you have tropical milkweed in your garden and didn’t cut it back in October, do it now.

Milkweed for habitats

Milkweed used for non-gardening purposes poses a more clear guideline. Dara Satterfield  recommends, “that habitat restoration for monarchs focus on native species of milkweed, which are synchronized with the monarch’s natural migratory cycle and do not enable the year-round breeding that can lead to high parasitism rates.”

Get to know soil

May we never refer to it as dirt again…

There are a couple ways to look at soil: one is as a static, inert growing medium and the other is as a dynamic, living environment of its own that affects the environment above ground. It is the latter context that scientists use mostly today. Understanding soil basics first facilitates better understanding of this much grander context.

World Soil Day is December 5, 2018

What is soil?

Unweathered geological material, mineral, or organic matter is the original source of soil, referred to as its “parent” material. Over time, and with the effects of climate and biological activity, the parent material breaks down to make up about half of the total mass of soil. The other half is made up of varying proportions of air and water. The specific qualities of a given soil—along with climate and surface features (slope or rock, for example)—determine what thrives in it.

It can take up to 200 years to produce
1 cm of soil.

According to the National Resources Conservation Service, there are over 1300 different soil types in Texas, and they vary widely throughout the state.

Capture

The General Soil Map of Texas  shown above, is the go-to for an overview of soil types. The Woodlands, for the most part, sits in area 51, which is a small portion of the Western Coastal Plain and Flatwoods region. This area covers about 16.1 million acres, dissected by many streams. It has many kinds of upland soils, which tend to be deep, light-colored, acid sands and loams over loamy and clayey subsoils that support pine-hardwood vegetation characterized by the ubiquitous loblolly pine.

Breaking it down

By simple observation, many clues can be gleaned about a particular soil’s properties.

Color. A soil’s color helps determine how much organic material it has, the various minerals present, and its ability to drain. The darker the soil, the more organic material it has. Darkness can also indicate slower drainage. Conversely, lighter soil is an indication that it’s lower in organic content and more highly leached.

Color can also give clues to the soil’s mineral content. Iron minerals are by far the greatest contributor to soil color variation, creating yellow, red, grey, black or brown hues.

Texture. Soil texture is important because it determines how well (or not) water drains through it and if it creates pockets of air. Texture is defined by the relative mix of three components:

  • sand, being coarse;
  • silt, being fine; and
  • clay, being finest.

The degree of coarseness or fineness provides clues to soil’s productivity. The coarser the soil:

  • the faster it drains;
  • the less water and more air it holds;
  • the faster it warms; and
  • the more easily it can be worked or penetrated by roots.

Depth. More can be learned from the soil’s “horizons.” Horizons are simply layers of differing composition. If there are key things to note about horizons, it’s that the A horizon, or surface, is the most fertile and has the best structure of all the other horizons., making it vital for plant life. Its depth can vary between just 2 inches to more than 12 inches thick. The B horizon, or subsoil, dictates how well water drains. Its depth too, varies between 2 and 12 inches. A subsoil of mostly clay will impair drainage and root growth. And these issues only increase the more shallow the surface soil is above it.

Soil Horizons

If there’s good news for the gardener who has less-than-ideal conditions in surface soil and subsoil horizons, it’s that improvements can be made by adding organic material, especially compost.

The value of loam

The relative proportion of sand, silt and clay gives soil what is referred to as its class. If there is a “perfect” soil class, it would be what’s called loam. Generally, loam is made up of equal parts sand, silt, and clay.

The best soil texture for growing plants is
what is called “loam.”

Loam = (<52% sand) + (28-50% silt) + ( 7-27% clay)

Loam soils are best for plant growth because the different-sized particles leave spaces in the soil for air and water to flow and roots to penetrate. The roots then can feed on the minerals in the suspended water. It retains enough water to keep the soil moist, but its texture is porous, allowing water to flow through slowly enough for the plants to access it, but fast enough to keep soil from getting waterlogged.

Tiny air pockets in soil are critical to support the animals that live in the soil, like worms and many types of bacteria. And one of the ways that plants get air is by absorbing it through their roots. Without air at a plant’s roots it would suffocate.

Deep sands do not hold moisture well and are often infertile. Clay holds moisture better than sands and may be more fertile, but they tend to swell when they get wet, which may limit the movement of water and roots. Clay cracks when they dry and the clods become very hard and difficult to penetrate.

Soil is alive

The key to understating soil’s properties is that they can determine the life it holds. Soil is a dynamic, interconnected, living thing—there’s a whole universe of life underneath our feet. It’s a web of energy conversions that fuels and makes possible life above ground. How big and diverse that universe is, is an easy measurement of how healthy the soil is.

As a living thing, soil quality is referred to as its “health.” The healthier the soil, the more it can:

  • Sustain plant and animal productivity and biodiversity;
  • Maintain or improve air and water quality; and
  • Support human health and habitation.

Healthy soil teams with life and supports its own food web as shown in the chart and illustration below, both from Soil Biology Primer, by Soil and Water Conservation Society.

Soil organisms

The Soil Food Web

Billions of bacteria, fungi, and other microbes that live within soil are the foundation of an elegant symbiotic ecosystem.  Healthy soil makes possible clean air and water, bountiful crops and forests, productive grazing land, diverse wildlife and beautiful landscapes.

Keep soil alive with organic material

Organic material in soil not only greatly improves its structural qualities it also helps create the right conditions for the life it supports. By helping maintain favorable temperature and moisture in the soil, earthworms, insects, bacteria, fungi and other organisms thrive. These in turn, break down the organic material into nutrients that make plant life flourish.

Up to half our household waste could be composted to nurture the soil.

Tips for maintaining healthy soil:

  • Disturb it less
  • Minimize compaction
  • Diversify soil biota with plant diversity
  • Keep roots growing in it year-round
  • Keep it covered
  • Compost, compost, compost

The great pumpkin

It’s an iconic symbol of the season. Porches, lamp posts, benches and steps are decorated with pumpkins—they are so ubiquitous that today 80% of the pumpkins grown in the U.S. are available in the month of October alone.

jack-o-lantern-3735387

The jack-o-lantern

For Halloween, these orange orbs are often carved with ghoulish faces illuminated with candles to the delight of children and adults alike. Originally known as jack-o-lanterns, we have the Irish to thank for this tradition that has folded into the fabric of our holiday. But the original jack-o-lantern wasn’t carved of pumpkin—pumpkins didn’t exist in Ireland. Ancient Celtic cultures in Ireland carved turnips. On All Hallow’s Eve, the Irish placed an ember in them to ward off evil spirits. The lore behind this tradition is the Irishman, Stingy Jack, who bargained with the devil and was doomed to roam the Earth with only a hollowed turnip to light his way.

There are other ways to use pumpkins as festive decoration. Use them as planters and set your Thanksgiving table apart.

History of the pumpkin in the Americas

There is more to the history of pumpkins to appreciate. One of the oldest known food crops in the western hemisphere, pumpkins are native to parts of the southwestern U.S., Mexico, Peru, Ecuador and Colombia. Pumpkins are known to have been cultivated since about 3500 BCE. Some archaeological evidence shows that ancient Aztecs used pumpkin seeds as a quick energy snack. Native Americans roasted long strips of pumpkins over a fire and also dried pumpkin, weaving the strips into mats. Throughout South and Central America pumpkin pulp has long been used as a treatment for burns.

When European colonists arrived in the New World, they relied heavily on pumpkin as a food source. Colonists prepared pumpkin by cutting off the top of the fruit, removing the seeds and pulp and replacing them with a mixture of milk, spices and honey. This food was the origin of the pumpkin pie enjoyed today.

flower-954484

Growing pumpkins

Cultivating pumpkins in the southeast Texas home garden is possible, although challenging. Pumpkins are heat-loving plants with seed germination dependent upon warm soil. In Montgomery County, late March to early April is the optimum planting time. Pumpkins require a day time temperature of 85-95 degrees with a night time temperature range of 60-70 degrees.

When preparing the garden for pumpkin growing, apply a generous amount of high quality compost to provide the nutrition requirements of these heavy feeders. Select a location with well-drained soil and few weeds, and select a pumpkin variety that’s small or dwarf since the large-fruited varieties require a space at least 18 feet in width and length for the vigorous vines. Smaller pumpkin varieties can be successfully grown in a space with plants two feet apart and rows 6 feet apart. If space is limited, you can even grow them in a pot.

Since pumpkin is a member of the cucurbit family, it’s susceptible to the same pests and diseases which plague squash, cucumbers and other cucurbits. Insect pests include:  squash bugs, squash vine borer, cucumber beetles and aphids. Plant diseases include powdery mildew, leaf spot, black rot, gummy stem blight, mosaic virus and bacterial wilt. Our local, frequently damp climate provides perfect conditions for these diseases. Removing plant debris and careful tool cleaning and sanitation will help prevent disease. For high quality fruit with a long life, harvesting at maturity is crucial. A pumpkin is mature when the entire shell has developed uniform hardness.

Cooking with pumpkins

A versatile fruit for culinary endeavors, pumpkin lends itself to preparations ranging from soups to pies and breads. No wonder the pumpkin has found its way onto the Thanksgiving table. For inspiration in the kitchen, see these pumpkin recipes  from Fine Cooking.

Nutritionally, pumpkin is a powerful food which is low in calories and fat but high in fiber, Vitamin A, Vitamin B, potassium, protein and iron. One cup of cooked pumpkin contains only 49 calories. Since every part of the pumpkin is edible, experiment with preparing not only the pulp but also the seeds, flowers, leaves and stems. Check out these guidelines for processing pumpkins.

Add beauty and manage rain with a rain garden

Rain gardens are simple landscaping features used to slow, collect, infiltrate and filter storm water. They offer a great way to turn a landscape “problem” into a real benefit. Rain gardens are planted areas—best added to a low lying area that collects rain water—that include deep-rooted native plants and grasses that are designed to thrive in wet soil, soak up excess rain water, and withstand intermittent dry periods.

There are aesthetic benefits to rain gardens as well, transforming a bare, wet area into a green, blooming habitat that provides food and shelter for birds, butterflies, and other wildlife. Amphibians such as frogs and toads will be attracted to this naturally wet area.

The problem

Increased stormwater runoff is the real problem. Add soil erosion to that and the result is vulnerability to flooding. Rain gardens help prevent both, helping to conserve water and soil.

Water Cycle

Consider the water cycle shown above and then add human development to the picture. Humans create stormwater runoff when natural areas are developed, replacing them with a sea of impervious surfaces fragmenting our green spaces.  Within a developed residential area, pollutants such as fertilizers, herbicides, pet waste, and oil are washed from lawns, streets, and parking lots into local streams and drainage systems.

Polluted runoff is the number one water
quality issue in the United States. 

How rain gardens help

While a single rain garden may seem inconsequential, it has great value, and several in a neighborhood collectively can produce substantial benefits. They slow the water down and let it collect in the garden’s depression, settling soil, silt and organic material that are washed by the water from higher ground. Water slowly filters back into the soil where it is needed most.  The deep rooted plants and grasses in the rain garden hold of the soil, keeping it in place. Rain gardens can also be designed to divert run off from sewer systems.

Plants within the rain garden increase the infiltration of water, giving the natural process that removes pollutants time to do its work. Naturally purified water then recharges the groundwater system. The end result is that by adding a rain garden to the landscape is a strategy that makes a difference.  Flooding is reduced.  Pollutants are filtered from the water. Runoff is diverted from streets and storm sewers.

Concern that a rain garden might serve as a breeding area for mosquitoes is not valid when they are sited correctly. Following a rain, ponding should last no longer than approximately 72 hours. This is a much shorter time frame than the 7 to 14 days required for most species of mosquitoes to develop and hatch from eggs laid in standing water.

Rain garden basics

Choose a site. Locate your garden in a low lying area of your landscape that tends to collect rain water at least 10 feet from your foundation. Choose a sunny or partially sunny spot. Also consider how it can be incorporated into your existing landscape replacing an area of traditional turf grass where the lawn slopes toward the street. An area that would catch roof run off or water from a down spout is perfect. If the rain garden is located on a slope, create a berm on the low side to retail water and soil.

Compared to a patch of lawn, a rain garden allows 30% more water to soak in the ground.

Test drainage. Test the location’s drainage before you create the bed. Dig a hole 8 to 12 inches deep and fill the hole with water. The water should soak in within 48 to 72 hours. Soils heavy in clay will drain much more slowly than soils heavier in loam, silt or sand. Amend sites heavy in clay with organic compost to improve the soil and help drainage. If the site doesn’t drain within 72 hours, choose another site.

Start digging. Rain gardens can be any size, but a typical residential rain garden ranges from 100 to 300 square feet. The depth of the garden can range between four and eight inches. Anything too deep might pond water too long and if too shallow, it will require greater surface area to effectively manage water.

Add plants. Choose a variety of native forbs and grasses, planting those with higher water tolerance in the middle of the garden. Include plants of varying heights and bloom times to maximize the garden’s depth, texture and color. Plant in groups of three to seven plants of a single species.  Go for diversity. In natural areas, a diversity of plant types not only adds beauty, but also creates thick underground root network that keeps the entire plant community in balance.

The chart below includes plants for our area suitable for a rain garden. Planting zones are indicated as:

Margin: the high edge around the rain garden that is the driest zone
Median: the area between the margin and center
Center: the middle of the garden that is deeper and will stay wet longest

Rain garden plant listHelp it flourish. Rain gardens can be maintained with little effort after plants are established. Weeding and some watering during dry periods will be needed the first two years.

Growing your own builds strong bodies and minds

The health benefits of vegetables are many, not the least of which is that they are important sources of nutrients, including potassium, dietary fiber, folate (folic acid), vitamin A, and vitamin C. Take the health benefits a step further and grow your own. When you grow your own veggies organically, the nutritional payoff is even higher (not to mention you ensure that no chemicals are being ingested with your zucchini).

Organic fruits and vegetables deliver between
20 and 40 percent higher antioxidant activity, according to a 2014 study published in British Journal of Nutrition.

And don’t forget another important health benefit to growing your own: Working an hour in the garden tending your harvest provides exercise benefits equal to a 30-minute jog.

Soul food

Did you know growing your own is also good for your soul?  “What?” you ask? Well, yes. A 2016 meta-analysis has shown a link between gardening and increased mental health. Getting your hands in the dirt brings you in contact with mycobacterium vaccae, a bacterium found in soil that may stimulate the production of serotonin—one of our “feel good” hormones. Gardening also opens your mind to nature:  bird song and insect sounds; colors and textures of plants; cloud patterns; changes in weather; soft breezes. All this good stuff has been found to:

  • Reduce stress
  • Reduce depression and lower anxiety
  • Increase focus and mindfulness
  • Inspire a sense of awe
  • Create a sense of hope and purpose

Nature Exploration Walks are good for you!

explore nature

Getting outside is a good thing. Learning about local nature is great! This fall, the Environmental Services Department is offering a new series of Nature Exploration Walks at The Recreation Center at Rob Fleming Park. Residents are invited to come out for a leisurely walk along the nearby trails with a trained naturalist to learn more about the most common wildlife in our area.

Did you know?  “There is a rapidly growing body of studies which show that people are healthier when they spend time in nature. Connecting with the natural world – whether it is in your backyard, out on the lake, or exploring a forest – has been shown to improve a wide range of mental and physical conditions. Conditions such as dementia, asthma, depression, ADHD, autism spectrum disorders, diabetes, and many others respond to time in nature. Physicians are rapidly learning about the benefits and have begun prescribing nature to their patients as a component of treatment and wellness.”  Daniel Porter, Medical Director, Lone Star Family Health Center.

Join in for the health of it!  Bring the family and discover what nature has to offer! The walks are FREE, but registration is required.  Click on the links to learn more and register today!
