Just give the plants some time. It's quite likely the female blossoms aren't being pollinated yet since it's early in the season. The little squashes under the female blossoms will abort, and that's what's happening. Some people like to hand-pollinate their early squash to get a jump on nature until the busy bees and other pollinators do it for them.

Do a GardenWeb search on "hand pollinating squash". There are several discussions on how to do it (it's pretty easy) if you think you'd like to. Otherwise, just wait a couple of weeks for the pollinators to find them.

I agree- I've had that happen. Look at hand pollinating, it sounds very intimidating at firsr, but is easy and will guarantee you some squash. Good luck!

Absolutely a pollination problem. Avoid using any chemical that will kill the pollinators who do come to help. Hand pollination will add a new dimension to your gardening exp.

Later will come a blossom end rot problem. Read up on that now. Usu. caused when irregular watering causes lack of calcium uptake by the plant.

A review of the several FAQs here on squash will be a big help to you. Linked one of them below but there are several others too on how to hand pollinate and how to control pest, BER in squash, and squash fruit abortion.
