Add 3 pints fertilizer to soil out from tree trunk. Best way I can explain this is put heels to trunk and fertilize outward that way you will not fertilize close to trunk always fertilize peachtree after fruiting and before blooms set. Now that take care tree hungry by multiplying root count so feed top with water elments needed. At end of porch water fall can be way to high in winter months winter is when roots of peachtree die badly cause over wet soil. Following spring and summer crop and heat load on plant will in short time lesser roots pick all water up. First leaves to eye lost color and fall from tree bumping limb hand will release many leaves limbs and trunk are dieing at sametime this complete cycle caused by winter pastthere as many methods as they are to lower water to tree in area like this I want list them gutter maybe the easy answer.
