Title: Low maintenance replacement garden in Ashburn , VA
Answered by: Barbara Medford


We live in Ashburn, VA (Northern VA). Our house is 10 years old and the contractor grade plants have died. We are planning on digging everything up and re-doing the landscaping in our front yard - right in front of the home. We do not have green thumbs and don't have a lot of time to care for the garden due to kids. So, we would like to know which plants/shrubs are best to plant in this area. The old plants were azaleas and evergreen shrubs but the azaleas never bloomed. We would like low height shrubs and some plants that would provide color year-round, if possible. Also, is there a dwarf tree that would be good as an anchor on the end of the garden? Thanks.


This is a great opportunity, since you are digging the old plants out anyway. Before you do anything else, get some compost (you can buy it in sacks at commercial nurseries), spread it over the existing soil, and then dig it in. Compost in the soil helps with drainage, assists the roots in getting nutrients from the soil that they need, and has nutrients in it, too. You almost can't put on too much. When the time comes to dig holes for your plants, it will be much easier. We will recommend plants native not only to North America but to your area. Plants that have been living in an area for millions of years will be accustomed to the climate, soil and rainfall; thus, requiring less water, fertilizer and maintenance. If you are unfamiliar with the use of native plants, you might start by reading our How-To Articles Using Native Plants and A Guide to Native Plant Gardening

You didn't say what your soil is (you may not know), but, again, natives to your area will like that soil, whatever it is. You also didn't say how much sun or shade your garden area has. We consider "sun" to be 6 or more hours of sun daily, "part shade" 2 to 6 hours of sun, and "shade," less than 2 hours. When we list plants we are suggesting, we will detail what kind of light requirements each plant has, and you can make your decisions accordingly. We will go to our Recommended Species section, click on Virginia on the map, and from there select on "herbs" (herbaceous blooming plants) under Habit. We will repeat that search on "shrubs" and "trees." You can duplicate this search, making your own selections by specifying bloom time and color, soil moisture and so forth. These plants are all commercially available, and if you have difficulty locating your selections, go to our Native Plant Suppliers section, type in your town and state in the "Enter Search Location" box and you will get a list of native plant nurseries, seed companies and landscape and environment consultants in your general area. They have contact information and maps, so you can check with them first before you make a shopping trip. Follow each plant link on our list to get more information, including (if you wish) going down to the bottom of the webpage on each individual plant to a link to Google on that plant.
