Fixing Yellowing Zucchini Leaves

How do you increase the yield of zucchini?

What to do with zucchini that got too big?

If you've got really big zucchini, cut them into roughly 3-inch sections and then hollow them into cups. If for some reason you've decided you're going to stuff smaller zucchini (petits farcis, anyone?), just shave a bit along one side and use that as the starting point. Don't throw out the cores.

How many hours of sun do zucchini plants need?

Can you save a zucchini plant?

Is it possible to overwater zucchini?
