I have a squash plant (zuchinni) that is starting to produce. The first one got a rotten spot on the end and died. I have had this happen in the past also. I had contributed it to the flower staying attached to the end of it and decomposing. Could that be the problem or is it something else? Also the leaves on these plants have blotchy white spots on them. What is causing this? We have a lot of rain for the last 3 weeks. I havent had to water in forever. Could any of this be caused by too much water?
