Monarchs on the move

The amazing monarch!

mxc-blog-monarch-g

Outweighed by a penny and powered by wings no wider than a toddler’s hand, the iconic monarch (Danaus plexippus) is right now embarking on the first stage of a migration that will cover upwards of 3000 miles, with some individuals traveling over 200 miles in a single day! They will wind their way across mountains, deserts, and cities, through multiple seasons and weather extremes, in a round-trip effort that will span five generations.

Monarchs in the United States are split into two populations, one east of the Rockies and the other west, along the Pacific Coast. The western monarchs spend their winter in California. Those to the east winter in the mountainous oyamel fir forests of southern Mexico.

It’s now in early spring when the eastern monarchs descend from the oyamel firs and move northward through Texas, allowing us to re-appreciate their beauty and marvel at their incredible stamina, navigational abilities, and the unique spectacle that is the monarch migration.

An epic journey

As temperatures warm and days lengthen, monarchs finish their development which was suspended over the winter, become reproductive and begin mating with fervor. Once mating completes, around February and March, the females leave the males behind in Mexico and head for the milkweed that is now sprouting across Texas.

And so the migration back to the United States and Canada begins.

The energy expended to complete this first leg of the journey is tremendous. After six weeks or so, now March and April, the female monarchs must find a milkweed leaf on which to deposit their eggs before they die. Once laid, four days will pass before the eggs hatch into voracious eating machines – baby monarch caterpillars.

Monarch caterpillars feast night and day on the leaves of their host plant and, incredibly, will gain 200 times their body weight in just two weeks. When the feasting ends they form their chrysalis and spend the next 10 days metamorphosing into an adult butterfly, vibrating with color and ready to renew the march north. This is generation 1, the offspring of the butterflies that overwintered in Mexico.

Several more generations will live and die over the summer, travelling further afield, but just one generation will make the entire journey back to the oyamel firs beginning in October.

The fall migration is even more dramatic than the spring, after reproduction has bolstered the population, dozens and even hundreds can be spotted hourly.

Creating safe havens for pollinators in our yards and communities provides vital waystations during spring and fall migrations.

The migration in crisis

Once 700 million strong, monarch populations have now crashed. It’s estimated the eastern population has plummeted by more than 85% while the western population is suffering even more – only 28,000 were counted this winter. Multiple issues are to blame:

Habitat loss and fragmentation. Over 160 million acres of monarch habitat has been lost to development since 1996.  Illegal logging of the overwintering sites in Mexico is also taking a toll.

Climate change. The increased frequency and intensity of extreme weather events can devastate migrating populations. Because of the incredible density of monarchs in the overwintering grounds, severe freezes there are catastrophic.

Pesticides and herbicides. Milkweed used to grow throughout corn and soybean crops across the south and midwest. But herbicides have driven milkweed to near extinction in these agricultural landscapes and depleted monarch populations along the way.  Monarchs are also being impacted by neonicotinoids, a new class of insecticides that spread their toxins through the plant’s tissues. Caterpillars that dine on these plants quickly perish.

OE. Ophryocystis elektroscirrha (OE) is a parasite that infects monarchs, causing them to die in the pupal stage or emerge deformed. Milder infections result in shorter life spans and an inability to fly properly. OE pervades in our area as non-native tropical milkweed (Asclepias curassavica) continues to grow through the cooler months, after native milkweeds have died back. Follow these important steps if you choose to grow tropical milkweed.

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.

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.

Healthier lawns, cleaner streams

One thoughtful action can help promote both: Think before you fertilize. All too often, lawns are fertilized too heavily, at the wrong time, or when they don’t need it at all—thanks to the formidable marketing efforts by fertilizer companies. Instead of automatically reaching for your spreader, consider what your lawn really needs and the consequences of over-fertilization.

blade-blooming-blossom-5865

Know what your lawn needs

Timing. The time to fertilize a lawn is when it’s growing more roots than blades; and to know when that is, know the type of grass in the lawn. Grass can be categorized in two ways: warm-season or cool-season. These terms refer to the weather in which the grass has adapted to grow. Turf grasses most common in our area, St. Augustine, Zoysia and Bermuda, are all warm-season grasses and start their growth in spring, making that the best time for fertilization.

Fall is when these grasses go dormant making fertilizers moot. Fertilizing at the wrong time can actually be harmful. Feeding your warm-season turf nitrogen in fall can force new top growth making the lawn susceptible to frost, shock and disease. What’s more is that this takes away energy from root growth, leading to weak, thin lawns.

No matter what, always follow a fertilizer’s instructions exactly when it comes to application.

Test it. Having said all this, don’t assume you need to fertilize every spring. The only way to know what nutrients your soil is lacking is to have your soil tested. Instructions for how to take a soil sample and the form for sending it to Texas A&M for analysis can be found with this link: Soil Test Form.

Go organic. If you find your soil needs supplemental nutrients for turf grass, consider using organic instead of synthetic fertilizers. Unlike synthetic fertilizers, organic fertilizers don’t create high levels of salts which kill beneficial soil organisms—the key to good soil health. And organic fertilizers work slowly, wasting nothing. They also improve soil texture making it easier for air to get to the roots and helping the soil retain water longer.

Organic forms of fertilizers include:

  • Alfalfa meal
  • Bat guano
  • Fish emulsion
  • Cotton seed meal
  • Seaweed
  • Manure
  • Compost

Refer to Best Organic Fertilizers for a full list of organic fertilizers and what they specifically offer.

How does this affect the quality of streams?

When quick-release synthetic fertilizers are over used, the chemicals are washed from our lawns in a downpour. The polluted run-off is channeled into the nearest waterway via storm drains, untreated and unfiltered. This water in turn contaminates our creeks, rivers and groundwater. High concentrations of nitrogen in water can also lead to an algae overgrowth, threatening the health of aquatic life.

Currently, over 80% of waterways in Texas are listed by the Texas Commission on Environmental Quality as “impaired,” creating poor habitat for aquatic organisms such as fish and turtles. High bacteria levels are another culprit and may lead to restrictions on water-contact recreation, such as  swimming and wading, fishing, and kayaking.

Other ways to help keep our water clean:

  • Pick up pet waste—it’s the number one source of bacteria in our waterways.
  • Maintain cars so they don’t leak oil and other chemicals onto driveways.
  • Compost, compost, compost.
  • Never flush unwanted or out-of-date medicines down the toilet or drain.
  • Minimize areas of turf grass and pavement while increasing areas of native plants
  • Install a rain garden

The way of the future: sustainable landscapes

Community resilience. Sustainable landscapes. These terms are becoming more commonplace and heard more often. Why? Because our collective and growing knowledge and experience tells us that global climate change is the impetus for increased catastrophic weather events.

What do these terms mean, exactly?

Taken one at a time, community resilience is the ability to anticipate risk, limit impact, and bounce back rapidly through survival, adaptability, evolution, and growth in the face of turbulent change, as defined by the Community and Regional Resilience Institute.

Turbulent change can include severe threats such as sea level rise, hurricanes, wildfires, drought, economic down-turns, social unrest, and other disruptions.

Environmental threats make up just one component—though significant—to the whole of turbulence that impacts resiliency, and designing landscapes that are sustainable is one way to help manage them.

The American Society of Landscape Architects defines sustainable landscapes best: “Sustainable landscapes are responsive to the environment, re-generative, and can actively contribute to the development of healthy communities. Sustainable landscapes sequester carbon, clean the air and water, increase energy efficiency, restore habitats, and create value through significant economic, social and, environmental benefits.”

It’s worth noting too, that a sustainable landscape is designed to be both attractive and to require minimal resources in terms of cost and ongoing maintenance.

Attend The Woodlands Township’s upcoming event:

Walk in the Woods Nature Lecture Series 

Thursday, October 11
6:00 p.m. to 7:30 p.m.
at HARC, 8801 Gosling Rd, The Woodlands
Lisa Gonzalez, President and CEO of HARC, will present:

Working with Nature to Build Resilient Communities

Registration is required.

A sustainable landscape can include:

  • Reduction of stormwater run-off through the use of bio-swales, rain gardens and green roofs and walls
  • Reduction of water use in landscapes through design of water-wise garden techniques (sometimes known as xeriscaping)
  • Bio-filtering of wastes through constructed wetlands
  • Landscape irrigation using water from showers and sinks (known as gray water)
  • Integrated Pest Management (IPM) techniques for pest control
  • Creating and enhancing wildlife habitat in urban environments
  • Energy-efficient landscape design in the form of proper placement and selection of shade trees and creation of wind breaks
  • Permeable paving materials to reduce stormwater run-off and allow rain water to infiltrate into the ground and replenish groundwater rather than run into surface water
  • Use of sustainably harvested wood, composite wood products for decking and other landscape projects, as well as use of plastic lumber
  • Recycling of products, such as glass, rubber from tires and other materials to create landscape products such as paving stones, mulch and other materials
  • Soil management techniques, including composting kitchen and yard wastes, to maintain and enhance healthy soil that supports a diversity of soil life
  • Integration and adoption of renewable energy, including solar-powered landscape lighting

That’s a lot. Let’s take a closer look at just two aspects of a sustainable landscape.

FIRST: Enhancing wildlife habitat.  Habitat loss, and the corresponding loss of biodiversity, can be curbed when we connect properties into networks of attractive, wildlife-friendly neighborhoods, cities, and regions. Starting with the home landscape, fragmented habitats can be rewoven together, creating spaces that are not only healthier for wildlife but also for people.

Watch this informative, short (4-minute) video produced by American Society of Landscape Architects, Designing Neighborhoods for People and Wildlife.

 

 

SECOND: Reduction of stormwater run-off.  In many communities, rain water flows into combined stormwater and sewer systems, which channel both sewage and rainwater together through underground pipes to central treatment facilities. Storms can quickly overrun these combined systems, leading to flooding with pollutant-laden water and even backed up sewage.

Watch this informative, short (4-minute) video produced by American Society of Landscape Architects, Leveraging the Landscape to Manage Water.

 

When these approaches are viewed with a wide scope and on a large scale, the potential impacts of sustainable landscaping are pretty powerful. At the same time, it’s important to recognize that change often starts on a small scale. And there might be no better place to start than in your own back yard.

Grow a native American vegetable and treat your landscape and palate alike

Helianthus tuberosus

Cultivated for centuries prior to the arrival of European explorers and settlers, our country’s only native vegetable is also a Texas native sunflower. The “jerusalem artichoke” or “sunchoke” is the enlarged underground stem of helianthus tuberosus, a type of sunflower in the aster family with edible tuberous roots. While commonly regarded as native vegetables, potatoes, tomatoes, corn and peppers all originated either in Central or South America.

20121210-sunchoke-kenji

Today, we take the food on our plate for granted, but the History of Vegetables  is a fascinating study.

The common name “Jerusalem artichoke” is likely a corruption of the Italian girasole (turning toward the sun) which is a trait shared by all sunflowers. In more recent years, the edible tubers of helianthus tuberosus have become known as “sunchokes”.

Sunchokes have a delicious, sweet nutty taste.  As an extra bonus, these tubers are nutritious and an excellent source of iron, potassium and fiber.

The original distribution of this native Texas sunflower is unclear because the plant was transported to many different geographic locations for cultivation by Native Americans.  Today, helianthus tuberosus can be found along the edges of wooded areas, in former fields and along roadsides.

Helianthus tuberosus

This showy sunflower is also sometimes grown simply for its bright yellow blooms and tall, fast growing stems. Broad, thick leaves and rough hairy stems add to the visual attractiveness of this native plant.

Blooming in late summer and early fall, helianthus tuberosus requires full sun to part shade. A tough and versatile plant, this sunflower will grow in moist or dry soil and tolerates drought, heat and frigid temperatures. Because of these qualities, it’s very easy to grow. Helianthus tuberosus is extremely useful in the garden where it can quickly become a temporary summer screen, a stunning background for a native plant border or the sunny edge of a natural wooded area.

Nectar source for butterflies

This particular sunflower is beneficial for both insects and wildlife. The large yellow flowers offer nectar for butterflies, pollen for bees while also supporting many predatory and parasitoid wasps, flies and beetles. In fall, the seed heads attract birds while the large plants offer cover for small wildlife.

Beekeepers have noted that helianthus tuberosus  is an excellent honey plant resulting in a clear amber product when harvested.

Very little is known about pests or diseases which damage this plant. It appears to be quite resistant, which contributes to its easy to grow nature. In the southeast Texas climate, the optimum planting time is early spring with the main harvest in fall. Since helianthus tuberosus is a perennial plant, once started in the garden, it’ll return each spring from tubers left in the soil.

Growing helianthus tuberosus in your garden or landscape offers new opportunities for applying culinary skills as well as providing beauty, food for pollinators and cover for wildlife.

The edible tubers or sunchokes can be harvested beginning within two or three weeks after the flowers fade. Harvesting can continue after the first freeze damages the stems and leaves of the plant. Each plant will produce approximately 2-5 pounds of sunchokes. When left in the ground after the first frost, the tubers become sweeter and crispier. To preserve the freshness, store sunchokes in a zip top plastic bag in the refrigerator. This strategy preserves the tuber’s natural moisture.

While sunchokes are frequently used in cooking as a potato substitute, unlike potatoes, they can be used raw and add a nutritious crunch to salads. Sunchokes are also an excellent vegetable for pickling.

If you like to get even more creative in the kitchen, try Pan-Roasted Sunchokes and Artichoke Hearts with Lemon-Herb Butter.

Looks and sounds delish.
