How to be a Good Steward? Start with One Thing

Posted on October 31, 2018 by Scott Vogt

Over the past year, we have been digging deeper into “Why” the Arboretum exists. There have been some lengthy conversations about events, classes, native plants, and relationships between people, plants and the land. One of the questions we kept coming back to was “What can one person do?” This idea that people change their perspective, build relationships, and/or develop empathy for the land one decision or choice at a time is an important concept for us to consider. So with that in mind, what is one thing you can do today to make our environment more sustainable?

These are just a few things we can change that will have a positive impact. There are hundreds more that are specific to your lives. Start with one thing.

Ride your bike or walk to the store.
Convert a portion of your lawn to native plants.

Plant a vegetable garden each year.
Turn the lights off when you leave the room
Pay attention to how much water you use both in your home and in your yard.
Recycle, recycle, recycle.
Create a compost pile and use the compost in your garden.
Maintain your car and properly inflate your tires.
Use LED bulbs in your home.

Make sure your house has the appropriate amount of insulation.
Realize you can make a difference.

We all have choices to make when it comes to helping the planet, but I believe environmental stewardship starts at home. If we choose to manage what we have in a way that saves us money and limits the negative impacts on the land, it is a win/win situation. This is my epiphany – small incremental changes in my lifestyle will do something good for the environment. I could always do more, but it starts to move the needle in a positive direction.

Maybe you are somewhat like me and find changing your behavior difficult, or you think stewardship is for someone else. That is not true. Small changes in the things we do combined with thousands of others making positive choices can make a profound difference in the long run. Don’t think of it as a compromise, but rather an investment in the future that allows future generations to live the same lives we now enjoy.

Start with one thing.

How to Create a Beautiful and Sustainable Garden

Posted on April 26, 2017 by Scott Vogt

With growing season and FloraKansas on the horizon, we have been asking a few questions of ourselves over the past few months about native plants. Certainly, we have seen the benefits of using native plants in the Arboretum and at our homes, but what would it take to convince someone to install them in their yard who has never tried them or is unfamiliar with them? What would it take to begin to change their minds?

We keep coming back to this idea of beautiful AND good. Aesthetics are important and we all want attractive landscapes, but so is this feeling that what we are doing is good for everyone and everything.

It can be intimidating to change the way you garden or landscape. Choosing plants just because they are visually appealing simply isn’t a good enough reason anymore. Creating a habitat using plants that are adapted to your site is a far better approach to landscaping. Designs that have attractive combinations of wildflowers, grasses, shrubs and trees may initially capture our imaginations, but more and more people are wanting these plants and their landscapes as a whole to provide additional benefits. Our gardens must now not just look good, but also do double duty to provide for pollinators, attracts birds and other wildlife, develop habitat and positively impact the environment.

The evidence that making such a change will really make a difference in our lives and in our gardens begins with the first native plant. I have seen it time and again – if you plant them, they will come to your garden. If you plant milkweeds, the monarchs will find them; if you plant penstemons, the bumble bees will find them; and if you plant asters, a flock of pollinators will cover them in the fall. It sounds so simple, but it is indeed true. These plants need the pollinators and the pollinators need these plants. The significance of planting your first wildflower can be both beautiful and good.

If you want to be part of the solution and do your part for nature by reducing water usage and eliminating chemicals, attracting countless forms of beneficial wildlife including butterflies, hummingbirds, and pollinators, cleaning storm water runoff, and having a beautiful landscape, start with a few native plants. Each of us CAN have a positive impact. We are stewards of these ecological, environmental, and sustainable gardens. An aesthetically pleasing landscape can also be functional and serve a variety of purposes.

Steps to a beautiful and sustainable landscape

Home landscapes can be transformed using native plants so that they are sustainable, easy to maintain, and beautiful. To start planning your native plant garden, be sure to attend our FloraKansas Spring Plant Sale and look over our 2017 plant list.

Principles of a Sustainable Landscape Design

Posted on March 9, 2016 by Scott Vogt

Through our work in promoting the use of native plants in landscaping, we have observed that homeowners and gardeners are becoming increasingly aware of the positive impacts they can have on the natural world. At the same time, they are looking for ways they can sit back and enjoy the fruits of their labor.

In a weekly article I receive online, landscape architects were asked to rate the expected popularity of a variety of residential outdoor design elements in 2016. Here are the top trends in landscape design, according to the American Society of Landscape Architects (ASLA):

Rainwater/graywater harvesting-88%
Native plants-86%
Native/adapted drought tolerant plants-85%
Low maintenance landscapes-85%
Permeable paving-77%
Fire pits/fireplaces-75%
Food/vegetable gardens (including orchard, vineyards, etc.)-75%
Rain gardens-73%
Drip irrigation-72%
Reduced lawn area-72%

These trends highlight the importance homeowners place on a functional landscape – landscapes that reflect their values and life style, gardens that center on solutions to problems rather than creating additional problems. Invest your time and energy in something that can make a significant difference. Think about these four principles as your develop your own sustainable landscape design.

Principle #1 – Treat Water as a Valuable Resource

We have seen the dramatic results of the drought in the west. Throughout 2011 and 2012, we endured our own drought here in Kansas. Certainly, the extremes we faced were not as severe as in places like California or Texas, but the impact on our landscapes can still be seen. Water demand was at an all-time high. Our landscapes were losing water faster than it could be replaced. In the aftermath, people began to ask tough questions about water use, irrigation practices, plant material and rainwater collection.

A sustainable design focuses on proper plant selection (i.e. native plants), drip irrigation if necessary and rain gardens or collection points to capture storm water. This new approach to design keeps water in the proper perspective.

Principle #2 – Value Your Soil

Like water, soil is a finite resource. There are choices we can make to improve our soil and to reduce or eliminate runoff and soil erosion in our landscape.

A sustainable design uses deep rooted perennials and grasses to hold the soil. These plants can be combined in appealing combinations. Beautiful blooms, textures and forms serve functional purposes in the design.

Principle #3 – Choose Native Plants

In my opinion, your first choice in a landscape should always be native plants. There are so many wonderful plants to choose for your landscape. I know there are some amazing adaptable perennials too, but if you start with a base of natives, you will be rewarded year after year.

A sustainable design matches appropriate plants to the site. Right plant, right place.

Principle #4 – Don’t Be Wasteful

Does your landscape add to the landfill? How much waste does it produce each year? Lawns are an important functional element in the landscape. I need a space for my children and pets to roam. They can also generate large quantities of yard waste, especially if you collect grass clippings. Do we need a huge lawn or can it be reduced in size and replaced with beautiful wildflowers, grasses and ornamental trees and shrubs?

A sustainable design evaluates every aspect of the landscape with the goal to reduce your negative environmental impact, while including features that are beneficial to the natural world and beautiful at the same time.

These homeowners chose to reduce lawn by replacing with wildflowers and shrubs.

Fighting for Water

Posted on February 11, 2015 by Brad Guhr

(Interested in Kansas water issues? Learn about our Kansas Water Symposium on Saturday, March 7 at Dyck Arboretum of the Plains!)

“Whisky’s for drinking and water’s for fighting.” ~Mark Twain is often given credit for this quote

Kansans for decades have utilized a seemingly endless supply of water to drink, to bathe, wash clothes, manage sewage, generate power, irrigate lawns, and grow crops. We give it little thought, we turn on the tap and it is there – clean, plentiful and inexpensive. Most families pay much more per month for their smart phones than for water.

The law of supply and demand is certainly in effect here to keep our water cheap. We have developed a state infrastructure making the availability of water plentiful and we access it in two main ways. Kansas reservoirs capture an average precipitation of 30-40 inches for use across much of Eastern Kansas, and one of the world’s largest underground water tables, the High Plains or Ogallala Aquifer, supplies water for most of Western Kansas. In South Central Kansas, we benefit from both supplies.

Experts are telling us though (and common sense should too) that this unbridled use cannot last. Our Kansas population continues to grow along with our collective thirst for water, and our water supply is not increasing to keep pace. The Ogallala aquifer as a whole is declining in its level, and stream sedimentation is diminishing the capacity of reservoirs. A recent 2013 presentation by Tracy Streeter, Kansas Water Office Director, shows that, depending on the region of Kansas that one examines, the trend lines of decreasing supply and increasing demand are set to cross each other in coming decades and in some locations coming years.

The sobering unknown factor in this discussion of water supply and demand is weather. Over the last 50 years or so, we have been lucky to have above average rainfall and below average temperatures. The Palmer Drought Severity Index (PDSI) helps us track this information and is one of the most widely-used indices to measure drought in North America. The PDSI measures the intensity and duration of long-term drought using precipitation and temperature data to determine how much soil moisture is available compared to average conditions. In a 2012 presentation by Tony Layzell of the Kansas Geological Survey, he shares the following graph of PDSI data in South Central Kansas:

Click here for the full presentation.

You can see that the two most recent significant drought events of 10-15 years in duration last happened in the Dust Bowl and the 1950s. For those of us that didn’t experience either of these drought events, the mini-drought of 2011 and 2012 gave us a little taste of relentless heat and drought, and it was distasteful enough. Here is the pending reality and problem – the law of averages is catching up with us and we are due for another drought event. Whether a little five-year event or a whopping multi-decade drought, it is coming.

We shouldn’t ignore this reality, hope that it never happens, and stick our heads in the proverbial sand in search of more prehistoric water that won’t be there or new reservoir storage, which is extremely expensive to create. Rather, we can proactively begin to appreciate how precious our water resources are and begin to use them more wisely. To survive, we will simply be forced to do so.

Solutions are available. Agricultural irrigation uses 85% of our state’s water and efficiency improvements are being made there already, but a drought will certainly force us to shift away from corn towards more traditional dry-land crops. Fossil fuel power generation is water-intensive and may diminish during a drought, but renewable alternatives are also available to pick up the slack. How we landscape our yards, parks, golf courses, etc. could significantly curtail municipal water use by shifting away from thirsty cool season grasses and utilizing more native, warm-season vegetation. We could be recycling our cleaned sewage water into drinking water; The City of Wichita Falls, Texas has been forced to do so because of a 5-year drought and cut their water supply demands over that period in more than half. The fact that North Americans wash clothes, flush toilets, and irrigate lawns, gardens, and crops with drinking water is laughable to much of the world’s population (including some other developed nations too) where access to clean drinking water is not a laughing matter. Thankfully, Kansas is in the midst of developing A LONG-TERM VISION FOR THE FUTURE OF WATER SUPPLY IN KANSAS and is considering all of these conservation solutions in addition to looking at increasing supply.

There are so many more issues to consider when discussing this complex topic of water. We invite you to the Dyck Arboretum’s Kansas Water Symposium on Saturday, March 7 and explore the above issues with eight experts speaking on a variety of water topics.
