I planted a Clematis ramona several years ago and always pruned hard in fall. Two years ago I missed the fall pruning and pruned in February when no new growth showed. Last year I had one flower, and so far this year no buds are showing. The leaves are healthy and growing. Will I ever have flowers again on this plant? When is the proper time to prune Clematis ramona, and can it be deadheaded?

Use a fertilizer high in phosphorous on your clematis. Something that is about a 10-20-10 NPK ratio or even rose food can be used to fertilize clematis. Anything having too much nitrogen will only result in an abundance of foliage growth with few blooms. You do not need to deadhead blooms but doing so will not hurt the plant.
