Snap! A young pecan tree breaks in the wind.
This tree was a victim of overzealous tree pruning. To get lower limbs out of the way of mowing or other tractor operations, too many low limbs were removed from this tree all at one time. This exposed a previously shaded trunk to intense heating by the midday and afternoon summer sun. This heat build up on the south and southwestern portions of the trunk killed the cambium halting all wood and bark growth. The resulting dead tissues attracted wood rotting fungi and the tree was unable to heal over the sun-scalded trunk.
Now that we've lost the entire top of this young tree and the remaining stump is severely damaged by wood rot, I've decided to cut this tree off at ground level and allow a stump sprout to form a new trunk. In a couple of years, we'll need to re-graft the tree. With all the root energy this tree will have to push new growth, we should be back to nut production in no time.
