Q.Green Squash Plant
My squash stems have started to just wilt and die. They are still green, but it looks like the stems have been squashed or broken and then they just collapse like they were frozen and then thawed. Mushy. I took those stems off and threw them away and finally pulled up the whole plant. I am seeing signs in the second plant but not in the third. I am just so frustrated with this. This is the second planting in containers. The first batch had a white fly infestation. Replanted in another container and moved it to the far side of the yard. The yellow squash was doing well but now has blossom end rot. I understand that is a calcium deficiency, which makes sense since it is a huge squash plant in a large container with tons of squash forming.
