Pecan tree
 

Recently moved in to a rural area. Very rocky soil. Native trees are
perennial and annual oaks, tons of junipers, and some real cedar.

Have two pecan saplings I planted in May. The one is front is in sad shape.
Some of the leaves took on a brown color, but did not immediately dry out
and fall off. Like it was diseased or something. There are a few sprouts
with very small leaves showing near the base. The pecan tree in the back
shows no signs of leaf problems. Lots of new growth near the base to about
1/3 of the way up, leaves almost full size now on this growth.

Sprayed the tree in the front with a fungicide. Seems to be clearing up the
brown leave thing.

There has been little or no new growth at the upper portion of either pecan
tree. This late fall or winter, should I top off both or one of the pecan
trees to promote growth? Or just leave it alone?
