Provide a fast-draining garden soil, and fertilize monthly. Scale insects, mealybugs and aphids are common insect pests. To provide shade, plant them among shrubs, and mulch the base of the plant to keep the soil cool. The soil should be fast-draining and rich in organic matter. Water generously, and feed with a balanced fertilizer in spring and fall.
Some types produce attractive flowers.
Don't remove the stem from the parent plant, just bury it in the nearby soil. In about a month new roots will form, and you can separate the plants. The process is called layering.
