Answer: Incomplete pollination can cause squash to stop growing and rot, but a disease called blossom end rot can do the same. If the squash is rotting from the end to the stem, blossom-end rot can be taking its toll on your squash. This condition is caused by wide fluctuations between wet and dry soil. To prevent the problem, water deeply and apply a thick mulch over the soil surface to keep evaporation at a minimum. Hope correcting the problem results in a bumper crop of squash for you!
