For many of us, this time of year is tough for our zucchini, squash and pumpkin plants.

Saving Seed: Will the seed produce plants similar to the plant it was collected from?

It can be very rewarding to harvest and save seed of ornamental and vegetable plants. But why is it that sometimes when we plant the seed we saved, the results do not seem to be very like the plant we collected the seed from?
