Can One Garden Make a Difference?

Posted on by Scott Vogt

One of the thoughts that I keep coming back to is this question of whether one garden can make a difference in the world.  This question makes me ask even more questions like: Can it slow habitat loss? Will it really attract pollinators? Can a conservation garden be beautiful and functional? Is encouraging biodiversity important? Can such a small garden mimic essential ecological processes? Will these pocket gardens connect people with nature? Even if only some of this is true, then conservation CAN indeed start at home.

 

Create Prairie Habitat at Home

Creating habitat gardens, prairie gardens, wildflower gardens or whatever we want to call them is now part of the conservation movement. Prairies as we knew them 200 years ago are never coming back to their original form. I would love to see large herds of bison meandering through vast expanses of prairie. We would stand in awe as we looked across the horizon on a rich and diverse landscape that moved with the gentlest breeze. But there remains only a handful of prairies that reflect this bygone era. Certainly, we must protect and try to enlarge these prairie tracts as much as possible, but encouraging the planting of thousands of small prairie gardens is equally important. We must begin at our homes by creating small vignettes that reflect our prairie heritage.

 

Give Back to Nature

It is through human intervention that these new landscapes can bring about change. Nature now relies on us to help more than ever. Conservation is like paddling upstream on a river. Progress happens as long as we keep paddling, but as soon as we stop the river pushes us backward. Incremental change or success is a result of our concerted efforts focused on moving us upstream. We can give nature back as much as it gives us. We rely on each other and we can no longer be separated from one another.

So to answer my question: Yes. Every garden is important in so many ways. To choose to restore, create or protect a habitat makes a difference. Each landscape/garden, no matter how small, can truly have a positive impact on the health of the environment. Imagine your garden habitat connected with hundreds of other prairie landscapes throughout each community, as shown through the Million Pollinator Garden Challenge. Pollinators and wildlife will benefit and we will feel good about the role we play as we care for nature.

 

Here are a few ways that incremental change can happen:

  • Reduce the use of chemical fertilizers, herbicides, and pesticides.
  • Use native plants as much as possible, because wildlife prefers these plants.
  • Plant trees and shrubs that develop fruit and berries that birds need as they migrate or overwinter.
  • Design a garden that has a variety of plants blooming throughout the year.
  • Incorporate plants that adapt to your site, which makes them low maintenance.
  • Transition parts of your lawn to wildlife habitat.

 

Instead of looking at all the negative that surrounds us daily, let’s focus on the positive role we can have in our neighborhoods.  It is easy to be all doom and gloom, but really we should continue to paddle forward. I believe small, steady changes provide us with a unique opportunity to discover what it means to be a steward of creation.  Who knows? Maybe your garden will be an inspiration that others use to begin their own journey. One garden can make a tremendous difference.

If you live in Kansas and don’t know where to start in establishing a prairie habitat garden, we invite you to further explore our Prairie Notes blog and attend our upcoming FloraKansas Native Plant Festival.

Landscape Scale Prairie Gardening – Thinking Bigger

Posted on by Brad Guhr

If you follow our blog, you are probably thinking about creating a prairie garden, are in the process of creating one, or have already done so. One of the reasons you might be participating in this enjoyable ritual is because you want to increase wildlife habitat for insects, birds, small mammals, amphibians, and reptiles in your home landscape. Indeed, if you increase native plant diversity in your landscape, you will attract more wildlife.

I want you to consider going a step further and thinking about how your landscape, which is increasing in biological diversity through your prairie gardening habits, relates to the greater landscape of your neighborhood. The study of landscape ecology tells us that ecological function generally improves as you increase the size and diversity of a particular ecosystem. For example, three landowners in succession creating prairie gardens will create more storm-water holding capacity and wildlife attraction than only one of those landowners doing so. And if those three adjacent landowners happen to be situated next to a stream, a park, a hay meadow on the edge of town, etc., the ecological function of those combined green spaces will increase.

In her 1993 book Noah’s Garden: Restoring the Ecology of Our Own Back Yards, Sara Stein tells inspiring stories about how she converted from traditional chemical and water-intensive suburban landscaping to a style that included more native plants, more habitat for wildlife and more connectivity with other green spaces. She promotes contiguous greenway corridors that allow for greater wildlife diversity and freer migration through urban areas. This was a very influential book that helped push me toward the pursuit of an advanced degree in ecological restoration.

I recently learned about an intriguing resource created through a collaboration between two entities I greatly admire – The Nature Conservancy and The Cornell Lab of Ornithology. Habitat Network brings people together to explore the effects of new conservation practices in urban, suburban, and rural landscapes. The Habitat Network website is a free citizen science resource that invites people to map their outdoor space, share it with others, and learn more about supporting wildlife and improving backyard habitat in cities and towns across the country. It takes the concepts of powerful GIS mapping software and puts them into a user-friendly, public platform that anybody can use. This looks like a great tool that I look forward to exploring and reporting on in future blog posts.

So, while I start mapping habitats and measuring the ecological value of Dyck Arboretum of the Plains and my home landscape, consider picking up a copy of Noah’s Garden and spend some time with Habitat Network yourself. Let’s think bigger, explore how we can document and expand our beneficial ecological footprint through landscape scale prairie gardening, and consider ways to convince others to follow our lead.

This is a conversation to be continued…

 

A New Way to Think About Spring Garden Clean Up

Posted on by Scott Vogt

This time of year, we get excited about heading outside for some spring garden clean up. The warmer weather signals that spring in just around the corner. All of last year’s plants, including grasses, perennials and the mountains of leaves blown into the garden, have to be cut down and hauled away, or do they? There is so much to do, but before you clear cut the garden, look closely at what you are removing from your landscape.

Through winter, your garden has provided habitat for many different beneficial insects and wildlife. By removing everything above ground, you are removing nesting sites and the homes of the pollinators you have attracted to your yard. All the old stalks, stems and leaves have protected and sheltered these insects through the coldest weather. So how can you save them and still get your garden ready for spring? Here are some suggestions that will save most of the beneficial insects hibernating in your garden.

Coneflowers and Little Bluestem offer great winter cover for pollinators and beneficial insects.

Carefully remove old growth

Most native bees are solitary creatures that overwinter in the ground or in hollow stems of perennial and grasses. Because they make their winter homes in some of the stems of your plants, cutting these plants to the ground will remove their nesting habitat.

An alternative would be to cut them down to 18 inches now, remove the upper portion and spread it loosely along the edges of your garden or property. Then you can go back when temperatures are consistently above 50 degrees and completely remove the rest down to the new growth at the base. By that time the bees and beneficial insects will have emerged from their winter slumber.

Another option would be to remove the stalks completely just like you have done in past years. I would then bundle the stems together loosely and hang them along the fence or tree line. From there, the insects can emerge and fly to your garden area.

I didn’t realize how many of these stems and stalks harbored the beneficial insects I want in my garden. It is important that we allow the life cycle of these insects to reach completion. I want to encourage you to be patient and careful when you cut down and remove the old growth from your garden. Either keep those plants up longer into the spring or keep them somewhere in your garden so the pollinators and beneficial insects can come out and stay in your neighborhood.

Strategically clean up leaves

We all have piles of leaves that have accumulated over the winter in our gardens. Just like the hollow stems of perennials, leaves protect beneficial insects, including ladybugs, damsel bugs, and butterflies like commas, morning cloaks and question marks through the winter. Other pollinators overwinter as eggs or pupae in leaves. Holding off leaf removal until daytime temperatures are consistently above 50 degrees will favor the hatching of a new brood of beneficial insects to begin their lives in your garden.

This simple and thoughtful approach to spring clean up will have a positive impact on the overall health of your garden. Instead of clearing your garden of beneficial insects, you will be connecting your garden with the complete life cycle of these pollinators. Your garden can have a positive impact on the plight of these endangered species. It will be a landscape that supports the pollinators and beneficial insects we enjoy and need so much.

Waking Up: The Exciting Life of Buds

Posted on by Katie Schmidt

The landscape may still be dominated by the browns and tans of winter, but inside the greenhouse is a different story -oodles of green buds bursting out of dormancy, waking up to warm, humid air! It’s refreshing to spend time around these green little beauties, and it is an indicator that plants outside will soon be doing the very same thing.

Buds excite us for many reasons. They portend flowers and color, and the lush greenness to come. But they also are a signal of life! Life after the cold winter months, life after dormancy – a breaking forth from a long sleep, part of the natural cycles of activity and inactivity that we all experience.

Beyond metaphor, their botany is just plain cool! Here are a few things to know about the buds emerging on your landscape plants at home.

Salix Mt. Asama is an early bloomer. It’s bright yellow and pink pollen clusters are showy, suspended on fuzzy, whimsical silks.

What is a Bud?

A pal? A friend? I certainly see them that way! But scientifically speaking, a bud is an embryonic shoot just above where the leaf will form, or at the tip of a stem. As I previously covered in my November post on pruning, there are lots of different types of buds: terminal buds (at top of stem), lateral buds (on sides of stem, producing leaves or flowers), dormant buds (asleep and waiting for spring), and many more.

Buds can be classified by looks or location.

Bud Beasties

Inspecting your buds is important to stopping a potential problem. The first thing to inspect for is aphids. Buds are succulent little treats for these pests, and have less waxy protective coating than mature leaves, making them an easy target. Often the buds won’t show much damage until you have a nasty infestation, so inspecting buds early is key. Be sure to look on the inner folds of the bud if possible, as aphids are quite good at hiding themselves.

Health Check

Even if you see buds on your trees, shrubs and outdoor plants, that may not be an indication that everything is A-OK. All too often I see lots of buds on my potted shrubs only to find out that they are dead – by pressing gently on them, they easily break off and reveal dead wood at the wound. If you have any doubt about the hardiness of a shrub or perhaps neglected your winter watering schedule, take a close look at the buds. Buds that are soft and mushy or dry and brittle are a bad sign, and may indicate dead wood that needs trimming back this year. Firm buds that don’t break off at a light touch, be they green or still brown, usually mean they are alive and waiting to spring open.

I’m dismayed that FloraKansas Plant Festival is still months away – so many early blooming plants are at their best right now, budding out and coming alive! Come visit the Arboretum and enjoy all the buds (and bulbs!) that are waking up!
