Trash to treasure: Winter gardening in your native prairie

Welcome to ChooseSustainable.org a blog about individual climate action. In this post I talk about winter gardening in your native prairie. Have you given a thought about transitioning your gardening habits from an endless list of “getting rid of” to welcoming, sustaining, and restoring of lost habitat? Do you know that restoring a piece of native ecosystem in your backyard is one of the most effective ways you can fight soil degradation, pollution, and loss of biodiversity?

In this post I talk about winter activities that help biodiversity. Remember that wildlife, just like us, inhabits the land all year round, not just in summer, and needs food, water, and shelter all year, just like we do. The good news is that when it comes to winter gardening less is more. In fact, our obsession with fall cleaning deprives other species of their winter shelter and eliminates important sources of food for birds that don’t migrate. Let’s get started then with our fall and winter trash to treasure list.

Leaves

Trash to us treasure to...Birds, insects, turtles, moths butterflies, fireflies, bumblebees, chipmunks, frogs and other amphibians…and the list goes on. Don’t trash the fallen leaves, gently push them out of the lawn area and collect them in a designated corner of your yard. They appear to be a lot, but after a couple of rainfalls they reduce to little. You can also divide them among the planted areas and around trees. I add to them all that is produced in the kitchen, mostly fruit and vegetable peels, and coffee grounds.

Beautiful perennials that provide good nesting for stem bees are: Elderberry, Joe Pye Weed, Goldenrods, Bee Balm, and Purple Coneflower.

SNAGS, branches, and twigs

Trash to us treasure to...Birds, bees, chipmunks, lizards, rabbits, squirrels. Our fall and winter cleaning often includes complete removal of fallen branches, twigs, and dead trees. Trees continue to live after they die. Hollow wood provides nesting places for wood nesting bees, birds, and small mammals. If you are lucky enough to have a wooded area in you backyard, you can leave dead trees (snags) properly shortened to avoid hazards, branches, and small piles of wood material. Dead trees at the edge of a backyard can also be kept and just cut back enough so that they are not hazardous. Fallen twigs and smaller branches can be piled up in a corner and left there to decompose. Here is a link to know more about wood nesting bees and nesting for pollinators:

Wood mushrooms decompose the hard part of the wood releasing nutrients that enrich the soil. Keeping snags and branches as much as we can ensures that the full cycle of life takes place in our yard.

LAWN imperfections

Trash to us treasure to...Ground nesting bees, bumblebees, chipmunks to name a few. Small holes in flowerbeds and lawns are likely due to wildlife trying to find a place to overwinter. Ground nesting bees can dig their own holes where the soil is soft, or they can also reuse holes dug by other wildlife. Extensive pesticide use on the lawn and obsession with lawn appearance are harmful to everybody and especially ground nesting bees. Read more here:

A small hole in the lawn can be used by ground nesting bees or other wildlife as winter refuge.

Finally, fall and winter gardening is a lot about observing, discovering, and planning for spring. Already in February we’ll be planning our cutting and sowing if we haven’t done it in late fall. Sustainable fall and winter activities ensure that life continues in your yard through the seasons and allow wildlife to survive harsh winters. HAPPY SOLSTICE DAY!

Helianthus Grosseserratus (sawtooth sunflower)

Welcome to ChooseSustainable.org a blog about individual climate action. In this series of short posts I present a native plant to encourage everybody to abandon our traditional way of gardening (basically a continuous fight against nature) and engage in sustainable gardening practices that nurture the ecosystem, sustain wildlife and foster biodiversity. I show the plants in a garden setting to dispel the myths depicting them as weedy and unsuitable for gardens.

It is not Autumn without sunflowers. Around mid September, when I start thinking about the upcoming winter I look outside at my outrageous sunflowers and the gloomy feeling is instantly dispelled. They smile back at me, while leaning on top of other plants, unorganized, and excessively tall. Yes they are bold and difficult to constrain, but after all that is exactly the reason why I had chosen them, for their high wildlife value.

You guessed right, this post is about native sunflowers, specifically the Heliantus Grosseserratus (sawtooth sunflower) variety.

Sawtooth sunflowers in September

Quick facts:

  • Zones:3-9
  • Bloom time: Fall (Sept)
  • Sun: Sun
  • Soil Moisture: Medium dry to medium wet
  • Aggressive: Yes but well manageable
  • Front yard: MAYBE
  • Height: 6-8 feet
  • Status: OK
  • Maintenance: LOW
  • Wildlife value: VERY HIGH

Wildlife connection: The entire plant from stems to leaves, from seeds to flowers is valuable to a variety of insects and birds. Rabbits like the emerging leaves in early spring. Caterpillars of dozens of butterflies and moths feed on the plant. Bees, including bumblebees, small flies, moths, and beetles visit the flowers. Birds, squirrels and small mammals eat the seeds through winter. Even my groundhog takes a shot at the small plants in spring.

I’ll start saying the this is the tallest sunflower in Illinois and it may not be suitable for small yards. It does spread but is actually not difficult to control because the roots are not too deep, so it is not difficult to remove occasional plants that may grow out of place. I mostly let it spread and remove it only when it starts encroaching on other plants.

The plant emerges in spring and develops during summer providing a beautiful deep green cover. The leaves are elongated and they have irregular edges that give the name to the plant. Multiple flowers generally branch out of the main stem in late summer.

Attractive flowers develop in early September lasting for several weeks. The flowers attract numerous visitors.

Attractive flowers last for several weeks attracting multiple visitors.

The usefulness and beauty of sunflowers doesn’t end with its bloom. The seeds accessible from spent flowers attract birds through fall and winter.

If you feel this is too much for your backyard, consider that there are other fantastic varieties of native sunflower that are easiliy grown and not as tall. For example downy sunflower (heliantus mollis) is only 5 feet tall. There are even some species such as the woodland sunflower (heliantus divaricatus) suitable for shade. I hope you will consider livening up your fall garden with native sunflowers. Every native plant you add brings back a piece of ecosystem that is vital to biodiversity.

Actions and News: New USDA plant hardiness map released

Welcome to YouChoose, a blog about individual climate action.

At the end of 2023 the USDA released the updated 2023 plant hardiness zone map. The previous map had been released in 2012. The map can be found here:

https://planthardiness.ars.usda.gov

The map provides a climatology of minimum temperatures across the US and is a valuable tool for gardeners to decide which plants have better chance of survival in a certain region. I am placing here the 2012 and 2023 maps next to each other.

The new map confirms the warming trend we all have been feeling to some degrees, especially here in the Midwest.

Temperature is one factor that affects your plants chances of survival, but other factors such as droughts and extreme events affect your garden as well. Using native plants in your garden helps mitigate the effects of climate change on your landscape. Native plants have uniquely evolved to withstand extreme conditions. In fact there are prairie plants such as the lead plant (Amorpha canescens, just to mention one) that can tolerate extreme droughts.

If you are interested in knowing more about hardiness and ecoregions check out this nice article from the National Wildlife Federation on how to plan a sustainable garden

https://blog.nwf.org/2024/02/hardiness-zones-and-ecoregions-for-climate-smart-gardening/

Don’t feel that your efforts are in vain. You can be sure that switching to native plants and pesticide-free gardening has a profound impact on the environment.

Catalpa speciosa (Northern catalpa )

Welcome to ChooseSustainable.org a blog about individual climate action. In this series of short posts I present a native plant to encourage everybody to abandon our traditional way of gardening (basically a continuous fight against nature) and engage in sustainable gardening practices that nurture the ecosystem, sustain wildlife and foster biodiversity. I show the plants in a garden setting to dispel the myths depicting them as weedy and unsuitable for gardens.

In this post I talk about a hardy blooming tree that I like very much: Catalpa speciosa (Northern catalpa). This tree is adaptable, resilient, fast growing and it makes great choice to replace invasive buckthorn at the edge of your property.

Catalpa can grow as a large shrub. If you zoom in you can see the flowers

Quick facts:

  • Zones:4-6
  • Bloom time: Spring (May-June)
  • Sun: Sun
  • Soil Moisture: Medium dry to medium wet
  • Aggressive: No
  • Front yard: YES
  • Height: 50-70 feet or 15-20 m
  • Status: OK
  • Maintenance: LOW
  • Wildlife value: Medium

Wildlife connection: The large flowers attract bumblebees and various types of bees. I also see moths and great insect activity on the leaves.

Catalpa is one of the few trees at these latitudes that produce large flowers. The leaves are also large and heart shaped. In this sense it is quite unusual and easy recognizable, you may even see it growing on the edges of roads depending on where you live. The plant blooms in Spring, around mid May and the bloom lasts about a month. The tubular flowers are easily recognizable from their markings.

If provided with enough room, the plant expands producing new small trees. This is a desirable feature if one wants to use the tree at the edge of a property. For this reason, although the value to wildlife is limited, this plant can still be considered important as a fast growing alternative to foreign species for screening.

Catalpa can also be shaped as a tree and it can occupy a nice prominent place in the middle of the yard. I have 2 catalpas in my yard, one is left as a shrub and one shaped as a tree.

This young catalpa was planted a few years back

Catalpa has a reputation for being weedy and for producing a lot of litter in fall. This can also be considered a plus. I collect the large fallen leaves and add them to the leaf compost pile. They do compost very easily, and are not a problem at all.

Catalpa leaves are a great addition to the leaf compost pile

I hope you will consider Northern catalpa for your garden, especially as an alternative to buckthorn. Every native plant you add brings back a piece of ecosystem that is vital to biodiversity.
