We used to have that problem. Now mos tof my trees, including 2 beautiful HUGE oak trees were taken by the hurricanes we had a few years back. I have one large oak in front and none in the fenced back yard. There are a few in the wooded land behind where we fence but I don't worry about that as the pups don't run in the woods. As nice as it is not to have to rake, worry over the oak pollen, deal with the oak "worms" and acorns & scoop all of it out of the pool ...... stilll, I miss the shade and beauty of those trees! So -- if it helps try to look at the positive side, the good things the trees bring. Helping?
