Why are my squash rotting on the vine?

Question

I’m a beginning gardener, and I thought yellow squash would be an easy way to start. So far, the vines have taken off, and I’ve seen two or three squash set, but they are rotting as soon as they start to turn yellow. They turn brown at the blossom end when they get about 2 inches long. I don’t think they are getting over watered. Could it be some sort of fungus?

Answer 1

They have blossom end rot. This article will help:
