Elevated garden box
I put in a ground level box garden in my back yard, but unfortunately, there are Melaleuca trees there. The roots from them overwhelmed the garden and stunted the growth of everything planted there. I believe that I need to construct an elevated box garden (approx 5' x 8') in order to keep the roots at bay. I would ask for the best practice in constructing one...maybe >3" off of my back yard surface. Any advice would be much appreciated, thanks!
