Should I dig up weeds and loosen soil under raised bed?
I am building raised beds. I have read that having 18 inches of loosened soil makes vegetables grow much better. I will have about 10 inches in the raised bed. Should I dig up weedsand loosen soil under raised bed?
I sure don't want to do all that digging if it serves no purpose, but if it would eliminate weeds and make the plants grow better, I want to do it now before I fill the beds.
Is this a waste of time?
Should I just put down news paper and skip all the digging?
Would cardboard have chemicals that would be harmful if I want to be organic?
