Ground covers are used to provide edgings to pathways, control erosion, and add interest to landscape design.
In agriculture, ground cover is the name given to plants that are low growing and are used to cover a large area, giving a carpeted effect. Using several ground covers can add variety to the landscape and prevent soil erosion. Many ground covers also grow well in shady areas where turfgrass will not grow.
Ground covers used as edging for pathways help regulate foot traffic in the garden. They also visually tie unrelated shrubs and flowerbeds together in the landscape. They can be used between steppingstones to provide color and for accent areas under trees where turf does not grow very well. For steep hillsides or banks where mowing is difficult, ground covers may be a solution. A homeowner trying to create an interesting landscape design will find the use of ground covers rewarding.
Planting Ground Cover
Plan to install ground cover plantings 6 weeks before the first fall frost. To prepare the soil, simply till up the entire area you expect to cover and work in 3 inches of soil conditioner, compost, or peat moss. Apply fertilizers according to soil test recommendations and work them in well. After planting, water the area thoroughly, and apply 2 inches of mulch. Once established, ground covers usually maintain themselves with minimal care.
Plants No Longer Recommended as Ground Covers
There are a handful of ground cover plants that were recommended in previous years, but are now viewed as poor choices. These plants easily invade nearby wooded or naturalized areas and take over ground that should be populated with native plant species. A complete listing of all invasive plants in your county or state can be found at www.invasive.org. Some of these species not recommended for Alabama landscapes include:
- English Ivy (Hedera helix)
- Vinca (Vinca major)
- Lantana (Lantana camera)
- Wintercreeper euonymus (Euonymus fortunei)
Many perennials or shrubs serve as ground covers. Choose those that are adapted to your soil type and fit with the area’s sunlight and water availability. The following is a partial list of plants that work well as ground covers in Alabama landscapes.
