Both thrive in full sun, are quite drought-tolerant once established and have few insect or pest problems. Clematis prefer full sun on the foliage and cool shade on the roots. 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.
