I have a zucchini plant that keeps sprouting new leaves but the old
leaves turn yellow then dry up and die as fast as the new leaves
sprout so my plant is the same size all the time and never makes any
zucchini. I looked for worms burrowed in the sprouts but that doesnt
seem to be the problem. is it too much water? too little? not
enough sun? too much sun? not enough fertilizer?

any ideas?
