common vinca management

Question

love my vinca, but has become very woody with white stuff on wood and leaves. Can I cut all to the ground level and will it come back nicely in the spring? SW Missouri.

Answer 1

You can do a hard prune on your plants. You can cut them to 4 to 6 inches above soil. Some gardeners actually mow the plant to make this hard prune.

Here are some links to help you.

It sounds like your plant may have Powdery Mildew.
