Care Information
Clematis needs support to grow. Use a fence, trellis, or an arbor to support the growth. If the buds fail to open or fall off before blooming, the plant may have become dried out. Excessively soggy soil can also cause bud drop. Keep soil evenly moist but not wet. Clematis are susceptible to stem rot and other fungi. It will show as black foliage or wilt. The plant does not necessarily die from this. Carefully cut off the diseased parts and dispose of in a plastic bag. Do not add to compost. Clean pruners with a disinfectant. Prune in spring to about 12". In severe climates, prune close to the ground. When planting, dig a large hole 24" x 24" and fill with good quality topsoil mixed with compost and some of the removed soil. In a sandy soil, dig a hole about 18" in diameter. Mix in the soil compost and the removed soil. To remove the plant from the container, cut the pot and gently ease out the root ball taking care not to disturb the roots. Stake or support the Clematis for at least one year to get established. Mulch is critical to keep the roots 'cool'. Put a 3-4" layer around the roots; but keep at least 6-8" away from the stem to prevent rot.
