A friend gave me a squash plant seedling. It was too cold to put outside so it grew in the house for several weeks and got blossoms on it, but accidentally dried out and lost all the blossoms. Its main growing stem has only two side leaves now. NO main stem to grow from now and hasn't produced any new leaves in 3 weeks. Will it ever produce more than its two leaves now that it doesn't have a main stem? Should I trim off one leaf to stimulate growth?
If the main stem died back, it has a 50/50 chance of growing a new stem. But really, at this point you are as good as starting from seed. I would recommend replanting seeds and starting over rather than waiting to see of this one recovers.
