Right Plant, Right Place

The most environmentally sound practice that you can use when selecting plants is to select plants that are compatible with your site. In other words, drought tolerant plants should be used in dry, exposed areas while plants adapted to wet soils should be planted in low spots or areas of low drainage. Light, humidity and soil type also need to be considered. Plants should be grouped according to their water, fertilizer and maintenance needs for ease of care. This will help prevent overwatering as well as over fertilization, which can harm local water supplies.

Proper placement of plants can reduce heating and cooling costs by providing shade or wind barriers.

If your goal is to provide for wildlife, select plants with berries, fruit, and nectar as well as plants that provide areas for shelter and raising young.

Native plants are an environmentally sound choice for many reasons, including ease of care and providing food sources for native wildlife. Since the goal of eco-friendly gardening is to help preserve the beauty of the local environment, we encourage the use of some native plants in your landscape. However, as with any plant, the proper location is important for its survival. Just because a plant is native to the area does not mean it will thrive if placed in the wrong location in your yard.

Work With Mother Nature, Not Against Her

What is the number 1 rule for creating an eco-friendly landscape? Learn to work with Mother Nature, not against her. To do that, you need to get to know your property on a deeper level.

Most of the ill effects of improper gardening are from too much water or too many chemicals. Choosing plants which are compatible with your site conditions and grouping them by their maintenance needs will require less of both.

A few words about water, or why you "should" be concerned about your landscape 

Although we have access to an abundance of water most of the time in the DC metro area, water conservation is still something we should all be concerned about. An American family of four can use 400 gallons of water per day, and about 30 percent of that is devoted to outdoor uses. More than half of that outdoor water is used for watering lawns and gardens. Nationwide, landscape irrigation is estimated to account for almost one-third of all residential water use, totaling more than 7 billion gallons per day. 

As populations increase, demand on our water resources will grow. Conserving water can prevent or postpone the expense of building or renovating new water supply facilities. 

Going hand-in-hand with the topic of water conservation is water pollution. Everything that goes into the ground around your home has the potential of finding its way into local water supplies. Rain and irrigation systems wash pesticides, fertilizers and other substances into our streams, reservoirs and lakes. These pollutants can harm fish and wildlife populations, kill native vegetation, foul drinking water, and make recreational areas unsafe and unpleasant.

How well do you know your property?

As property owners, we each own a piece of the earth. To take care of it, and the rest of the surrounding eco-system that it connects to, we need to get to know our property.

There are some things that you can learn about your site conditions from books and online resources. For others, you need to go out and spend some time in your yard.

For example, you probably already know your Plant Hardiness zone. This zone number is listed on many plants and will help you buy plants that will tolerate our winters.

You may also already know the average rainfall and high and low temperatures for your area.

For the other aspects of your property, I suggest at least five nice slow walks around your property. Ideally, these walks should be taken at different times of the day and during different weather conditions. Why? Because you want to find out things such as where the sunny and shady spots are and where water collects after a rain.

If you have a printed survey of your property, make a copy of it and use it as a diagram to make notes during your garden walks. If you do not have a printed survey, it will be helpful to draw a sketch of your property and make notes about what you learn about your landscape.

When you take your walks, pay attention! Turn off your ipod. Leave your phone inside. And really notice what is going on around you.

In a previous post, I suggested that you keep a garden blog or journal. A journal is the perfect place to keep track of what you discover while you are getting to know your property.

If you are making a drawing, mark areas of shade and sun, slopes in the terrain, low spots that will hold water and any large trees and plants that you plan to keep. If you enjoy gardening for wildlife, I also suggest that you make note of any birds or butterflies you see in your yard and what plants or natural elements they are using.  

Things to Keep in Mind as you Get to Know Your Property
  • Are there any local deed restrictions or other ordinances that will affect your landscaping plans?
  • Take digital photos of any unknown plants to your local nursery or extension service office for help with identification. Are any of your current plants native or invasive species?
  • What kind of soil do you have? Read this article, Knowing Your Soil, to find out.
  • Have you had the pH of your soil checked? Here is a pdf document to help you with this step: Soil Sampling for the Home Gardener.

Decide what you want for your landscape and make a plan

What are your goals with your landscaping? There are many benefits to proper landscaping, including aesthetics, improved resale value, noise reduction, climate control and wildlife habitat.

How do you plan to use your yard? Do you need play areas for children, relaxation areas for adults, or vegetable gardens for nourishment? Do you enjoy gardening or would you rather have a yard that practically takes care of itself?

If you don't intend to do your own landscaping or lawn maintenance, read these Tips for finding an eco-friendly lawn care company.

Rain Garden Workshop - October 23rd

Beautifying Your Yard for Clean Water - Rain Garden Seminar for Homeowners
Saturday, October 23
9:30 a.m. - 12:30 p.m.

Virginia Tech's Northern Virginia Center Room 100 7054 Haycock Road Falls Church, VA 22043

Homeowners will learn how to properly site, design, construct, and maintain a small scale do-it-yourself rain garden!

This workshop is co-sponsored by the Northern Virginia Regional Commission, Northern Virginia Soil and Water Conservation District, Arlington County Department of Environmental Services, Virginia Tech - Natural Resources Program, Virginia Department of Conservation and Recreation, and the Community Appearance Alliance of Northern Virginia.

Rain gardens, also known as bioretention areas, are attractive landscape features that allow rain water and snow melt to infiltrate into the ground. A layer of mulch and plants intercept water running off streets, driveways, and rooftops, slowing its flow and removing pollutants before the water reaches local streams, the Occoquan River and the Potomac River, drinking water supplies for the region.

For more information, visit the Northern Virginia Regional Commission website.
