GROUND COVERS

HABITAT: Annual and perennial plants native to various sections of the world used as below with the following descriptions and hardiness zones.

USES: Cover for bare areas, carpeting shady areas, mulch for weed control, setting for bulbs and garden statuary, soil erosion, variety, regulate foot traffic, tie in shrubbery and flower beds, reduce maintenance.

HABIT: Low growing, vining, creeping of various heights, textures and colors. Evergreen or deciduous. Broadleaf or narrow leaf. Slow to rapid growth.

SEED GERMINATION: As listed with each item.

CULTURE: Generally all require similar treatment; good garden soil,  deeply worked, enriched with humus (leaf mold, peat, compost, etc.), with well-rotted manure or a commercial fertilizer such as Mag Amp, a slow release fertilizer which supplies nutrients as the plant requires it; incorporated into the soil, will supply nutrients over an entire year or growing season. Some require sun, some shade, or combinations. All demand good surface and internal drainage. Dry to wet soils. An initial mulch or winter protection is generally advisable. Planted at any time of the year if they are well rooted or in containers. Late fall, winter, and early spring. Spacing depends on species (small plants 4-8"), vining plants 12-18", and small shrubs 3' (the closer the spacing, the quicker the covering). Keep area free of weeds and grasses until established. Trim plants which get out of bounds and prune to remove weak, diseased, or unsightly growth.

INSECTS: Like all plants, preventative medicine is better than waiting until it is "too late". Red spider, worms, etc., are most common. Sprays of Malathion, Rotenone, and Permaguard are helpful.

DISEASES: Not too many, but usually associated with poor drainage, unsanitary conditions; air circulation, sanitary protection will control. Captan or Benomyl most helpful with rotting of plants and mildew.
