Here's another tip. You, in West Virginia, can likely start squash seeds directly in the ground if you wish and have plenty of growing time. In MN we'd have to wait until late june/early july to do that trick, and we don't want to wait so we transplant on our farm. However, if you want to start some pots for transplants in WV (to make sure a row gets 100 percent fill rate or to use landscape fabric or mulch), then make sure you choose the larger size trays (36 pot count per tray) or use something like dixie cups with some drainage holes, because these seeds are HUGE, the plants pop up quickly and need to be IN THE GROUND after the transplants are about 2 weeks old (maybe sooner if they've been in warm conditions). Otherwise they get rootbound in the pots and will never do as well as they could have (they may even start fruiting at a small size and give you small squash fruits). Same goes for cucumbers and melons, I believe they are all in the "squash/melon" family. They all come up strong, fast, and develop roots quickly.
