Question
My squash has flowers on them them they close up and fall off without producing the squash.What causes this and what can i do?

Answer
Jenny:

You have what is called a "blossom drop" situation. This can be caused by a fungus or a virus. You can try by spraying with friendly Seven. If this does not work, try a general purpose light spraying of a fungicide from your local nursery.

Best wishes.
