Growing & Maintenance Tips:

Clematis can be grown in full sun or light shade, but its base and roots must be completely shaded. You may need to plant a small shrub or large perennial directly in front of its rootball to keep it cool and shaded. A thick layer of mulch will also help to keep the soil moist. This vine prefers to be grown in moist, well-drained, slightly alkaline soil. Adding lime to the soil will help to provide these conditions. When planting clematis, it is important to plant it 3" deeper than it was in the original pot. Bury the first set of entire leaves to encourage the production of strong shoots from below soil level and to discourage clematis wilt.
