zucchini rotting on the vine
I'm not sure if rotting is the right word for it, but I have had several zucchini that will grow quite large in length, 6 or 7 inches, and be quite large at the base, about as big around as an egg, but the large part is only about 2 inches up. The remaining 4 or 5 inches will stay rather slim and will turn mushy and then go yellow and rot away starting at the blossom end. They never get quite big enough to eat, although I have gone ahead and picked some before they get too mushy, cut off the soft part and use the rest. Can anyone tell me what would cause this? Thanks.
