I have a very old oak tree in my yard. It was there long before we built our home next to it. I have a little area in the sun but a few feet from this tree. When I first dug in the soil I noticed a lot of roots but thought I did a good job on preparing the soil. Now anything I plant there doesn’t grow. It does stay alive, it is green but doesn’t grow. Only a few flowers actually get blooms. Does anyone have any ideas on how to get around this problem? I’m about to throw in the towel and put some sort of fountain in this area instead.
