Squash help needed Both my yellow squash and zucchini plants looked healthy and beautiful on Saturday. Today my yellow squash looks like it is going to die. The stems on all my squash plants look like this - brown with holes. Is this squash borers? Or is it something else? I treated them all today with an organic pesticide but not sure if there is something else I should do. Originally by u/Bald_Goddess on Reddit: https://tinyurl.com/2cvvh6ew
