I have a small garden in my backyard of squash, tomatoes, and some peppers. Nothing is being bothered except for my squash plants. I've had a few that will begin to grow under the flowers, and after they get about as big as the cap to a highlighter they suddenly disappear, like someone just cut it off with some scissors. I've read that this may be due to cutworms, however only the part with fruit is affected. I have not found any other stems severed in such a way.
This is my first time growing first time growing squash, so I really don't know what I'm doing.
Thanks for any help.
