plants are rotting
I have a few zucchini plants and over the last two seasons they have produced, however they seem to die. After looking at the root it looks rotten. I was told it is due to a “vine bore” type bug/grub. We lost a few plants last year’s such as; zucchini plants, melons, cucumber and pumpkins. I was told the only way to rid these bugs/ bore grubs is to let the garden sit for an extended period of time (years) or move it. Can you help?

Sounds like you are referring to the squash vine borer. It is always a good idea to rotate crops to lessen disease/insect pressure, but if you have a small garden this is not always possible. Even if you move to another area, you will eventually have the problem again. This can be a common pest of squash and pumpkin. However, it is rarely a pest of cucumber, gourd or melon. Take a look at our website above for prevention and control.
For cucumber you may be referring to bacterial wilt. See common problems on cucumber and melons http://extension.umd.edu/hgic/learn/cucumbers
