Q.Yellow squash and zucchini
This is my first time growing a vegetable garden from seed. My yellow squash and zucchini have developed some sort of virus, but I can’t seem to determine for sure which type it is, or how to handle it. I’m so disappointed and would appreciate any advice!

I'm sorry your squash and zucchini plants aren't doing well!
