I recently purchased a house but the entire property was filled with mature pines, oaks and maple. We finally had about an acre cleared out so we can start planting fruit trees. I am torn about what to do with the stumps. I have seen some people hollow out the centers out of stumps and use them as planters, generally with annuals. I was wondering about something similar but with fruit trees. My thought was to cut the stump flush with the ground, hollow out roughly a foot wide bowl and drill some 1/2" holes through the base of the bowl until I reach soil. In my mind this does several things. It saves me the time, money and fuel of renting a stump grinder or mini-excavator and it should speed up the decomposition of the stumps as well keeping the organic material in the ground.
Has any one attempted this with known results or does anyone have any resources about this idea?
