I'm quite sure this has more than likely been commented on, but I didn't find anything in search. For the last several years we have put out zucchini plants. We may get 4-8 zucchini and then the plants die. For instance, this year we planted garden the 3rd week of June, as of yesterday, all of our zucchini plants have died. They are big, thriving plants one day and the next they are wilted and dead. Does anyone know what might be causing this? It is very frustrating. This year and last, we planted them in a raised bed. They are planted in the same vicinity as before the raised beds. We did our RB's lasagna style last year. If it were something in the same soil, I would think it was there. When we built the RB's, we used other dirt from another spot in the garden. Some one suggested a spider mite. All I know is they are healthy looking one day and gone the next!
