Clematis Growing Tips

Most clematis prefer full sun or light shade, although there are many that prefer more shade. Clematis need cool roots that are shaded. Plant a small shrub or large perennial directly in front of it to shade roots. A thick layer of mulch will also help to keep the soil moist. This vine prefers to be grown in moist, well-drained soil. Plant Clematis 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.
