since no one replied to you... assuming no disease (eg, the squash and
cukes may get borer, or mildew, or both), the broccoli and peas will
certainly stop in the summer. The corn is a one time thing. The beans,
it depends. string beans keep producing for a long time, but shelling
beans come all at once. indeterminate (tall) tomatoes should keep
producing, while determinate (bush) may come all at once. cukes and
squash should continue producing into the fall. At any rate expect some
slowdown, even for continuously producing crops, after the first two
months of harvest.
