I have a big oak or maple tree in rea yard.
It seems to have many root cluster going threw the yard.
Most of the yard has fairly good grass, however every year (past 4-5), I have tryed to grow new, seed over old, new loam some places, fast grow, sun/shade, and contractors blend.
Stater ferlilizer, additional fertillizer, followed growing instructions.
It seems to take a large amout of watering in some areas
and still not get desired results.
what am I doing wrong?
