   Dan, I love your photos. Why not once in a while let us guess the location? Could be fun I think.

   Speaking of foliage, why is it that two trees, planted at the same time,only 20 or so feet apart, both pin oakes, shed leaves at such a different rate? I have one almost bare, while the other has well over 50% of its leaves left.

   david: what triggers a particular tree to change and drop its leaves is a complex physiological process involving a lot of environmental triggers. Truthfully, there could be 50 different reasons why that’s happened with your trees. Once the leaves have fully turned and are ready to fall away, it’s only a matter of which tree takes the most direct hit from the prevailing winds.

   David.
   Simplest explanation is genetic differences between the trees. If the trees grew from seeds they will have different genes. They will react differently to the changing seasons. Grafted trees are clones so they have identical genes.
