Clematis Plant Care:
Pruning Type 1 - Flowers are produced from old stems, so pruning is done immediately after flowering has stopped. Prune by removing all dead and weak stems immediately after flowering. Larger, older plants (over 15') are normally not pruned, especially if growing in trees. Tie stems into place after flowering. New growth will begin, and these are the stems for next year's flowers. If intertwining Clematis, pruning will be easier if you select varieties with the same pruning type.
