I am also experimenting this summer with a planting rotation whereby every two weeks or so I put another dozen zucchini seeds in the ground. My goal is to have a moderate amount of zucchini ripening all summer long instead of a glut of zucchini in mid-July for which I have to find willing recipients among my neighbors, family, and coworkers.
I used to be among the "grow-the-biggest-zucchini" gardening crowd, but my wife educated me that the best-tasting and juiciest zucchini are the ones that are just a few days old and that measure 9 to 12 inches in length. Few gardening pleasures can top the taste of a fresh-picked zucchini on scorching summer afternoon.
