I learned a lesson from squash...and now I pay closer attention to what I am planting where. I save seeds. I planted two different varieties of squash...zucchini and yellow squash next to each other...from saved seeds I had great luck with for several seasons. I harvested the seeds and planted them the following season. The "squash" that was produced was not what I expected! Cross pollination is amazing! They grew into amazing plants but the produce was not so amazing! Now I am very careful about what I plant where...hybrids.
