Q.My Squash and Tomato Blossoms Are Falling Off Before Fruits Are Formed, Why?
I have several other vegetables planted as well in raised beds. This is happening to my tomatoes and peppers also. I water once daily around 4 pm until the ground is good and saturated. My soil is a mixture of jungle grow, cow manure and peat. Everything gets full sun all day long here in Florida. What should I do?
