Hello everyone. My name is Chris. I would like to kill all the insects in my raised bed garden. But not with a pesticide. What can I use to completely wipe out the garden and hopefully start fresh again for the spring time? Living in Florida is horrible for insects and bugs, and I feel as if there are bugs that are living in the soil and when I plant anything they decimate the garden. I have naturally occurring pumpkins that like to grow in the garden, and every time they start growing, they will die. One year I had over 20 pumpkins grow with no problems. I wasn't trying to grow them, they just grew from throwing halloween pumpkins into it. But something is killing the pumpkin vines from the inside out. I would appreciate any help. Thanks.
