I have a garden bed that I planted tomatoes , then broccoli. Both were eaten to the stems. The kale was eaten to the stems in another bed. I have tried spraying and protecting the plants but nothing worked. I let the bed go to seed and volunteer tomatoes grew untouched. Since the tomatoes were thriving, I planted a few broccoli as a test and again they were eaten to the stems. The brocolli in the next bed that had basil in it is fine. What is going on?
