I think I planted my cucumbers and squash too close together. The

cucumbers.

1) Is this a common mistake?

It happens.

2) Is the food edible?

Yep. Had watermelon squash once. Quite tasty once I stopped trying
to catagorize it.

3) Once they've cross-bred, anything I can do.

Keep them from having children?

Look at it this way, you could have crossed your squash with gourds
and had to use a table saw to have dinner.

They're all mutant if you go back far enough.
