Once you have found a suitable location, raise a planting hole in the ground that is so deep that the bottom two pairs of leaves can be buried. This serves as a precautionary measure against the widespread clematis wilt. If the plant is attacked by this fungal disease, then it is more likely that it drives out again, if you cut generously.
