I have a small garden patch and the first year every thing grew so well, but last year my onions and all my root veggies were infested with a root maggot. Is there any other way to rid the garden of root maggots other than using a pesticide? Plus, two years in row I have planted spaghetti squash and they start to produce but then the squash die and fall off, why?
