Cover the ground with a beautiful carpet of foliage, thereby reducing erosion and providing a mat that inhibits weeds. Good ground covers spread easily and quickly and will grow underneath other edible plants. They need weeding and or mulching and watering to get established. Since it is often not affordable to plant groundcovers so close together that they cover the ground immediately, people often plant 1-2 feet apart. Plants fill in and cover the ground in a year or two. Chunks of most established ground covers can be removed to extend a planting.
