Our zucchini was like that. I got some at the very beginning and then 2 mos of nothing. I just picked the first one in 2 mos yesterday. I wonder if they got some kind of disease. I have a friend that said the same thing, a few at the beginning of summer and then nothing.
My tomatoes are finally turning red. We have had a cold summer with not enough heat and the tomatoes were really late this year.
