From a purely practical point of view, groundcovers offer alternatives to turf in hard-to-mow sites and reduce the need for watering and other maintenance. Groundcovers conserve moisture, maintain even soil temperatures and stabilize soil in erosion-prone areas.
Groundcovers can create visual pathways to help direct foot traffic and can help link ornamental plants or provide transitions among outdoor spaces. Many groundcovers spread quickly to form dense plantings, which can help to inhibit weeds.
Selection When selecting groundcovers, consider their spread, height, location, function, foliage texture and color. Since no single species of plant works for every landscape situation, pay attention to soil conditions, light and moisture requirements. Some plants prefer partial shade, while others thrive in deep shade or full sun; a few tolerate a wide variety of light conditions. The most effective selections are chosen with an eye for how plant sizes relate to the intimacy or expanse of particular landscape sites.
When groundcover will be used to prevent soil erosion on a steep slope, it should have an extensive root system and vigorous growth habit. Some groundcovers do not withstand excessive foot traffic. Before planting anything, create a walkway through areas intended for pedestrians.
Soil Preparation A key to successfully establishing groundcovers is proper soil preparation. Before planting, eliminate weeds and turf from the area. For large areas, use a sod-stripping machine to clear turf. For weed control, consider a glyphosate herbicide or soil solarization. The process of solarizing uses the heat of the summer sun to raise soil temperatures high enough to kill harmful organisms and seeds in the ground. Solarize soil by laying strong transparent plastic over cleared and moistened soil. Seal the edges with soil and leave plastic in place for four to six weeks.
