Why are my zucchini dying on the vine?

How do I protect my zucchini from bugs?
How to Prevent Squash Bugs
- Prevention is key: In the fall, be sure to burn or compost old squash vines to rid your garden of any possible shelters for breeding and over-wintering.

- Practice crop rotation.
How do I keep bugs off my zucchini plants?
Cover your zucchini plant with a single layer of horticultural fleece as a barrier to bugs. Hold it in place with stones and gather the fleece beneath the stones to create a tight, firm edge against the ground. Remove it when the squash begins to flower to allow bees access for pollination.
