If you've ever grown zucchini, you know the trick isn't so much in getting it to grow as it is making use of all the zucchini your garden produces. I've learned from past gardens that a couple mounds of zucchini produces plenty of this fruit for my family's use and enough to share, too.
This video from the Garden Guru discusses a problem some gardeners have with zucchini, which is the squash yellowing and rotting before ever turning green. According to the Garden Guru, this is an issue of the plants' flowers not being pollinated. The video shows you how to do it yourself. It's a simple procedure that doesn't require more than a few minutes, especially after you've done it a few times.
Zucchini, like tomatoes, is not actually a vegetable, but a fruit.
