I have several raised gardens that were built about 4 years ago. Last year nothing grew in my gardens because tree roots had taken over. I cannot find any articles to help me with this problem.
I started my beds with thick layers of cardboard on the ground, but by the 2nd year the roots were already coming through. Moving the beds is not really an option. I did dig all the soil out of 2 of the gardens last week, laid down more cardboard and black weed barrier and I'm hoping that will buy me at least 2 years of root free garden.
Any advice?
