Winter Damage/Decline on a Honeylocust Tree

Winter Damage/Decline on a Honeylocust Tree. Observing the decline of this Honeylocust tree I see that more than half of the tree failed to ever leaf out in the spring. This indicates winter damage. During a warm spell in the winter months this tree started to send up water and nutrients. When the next freeze occurred the water inside the tree freezes and expands killing the tree tissue.

Decline in 1 out of 4 Austrian Pines



Decline in 1 out of 4 Austrian Pines. At first glance it may appear to be pine wilt. Pine wilt kills a pine tree completely in the fall. With closer observation I see that this pine still has green/live growth. The steady decline over several years of one out of four of these pines is likely due to this Austrian Pine being planted too deep.

Herbicide Drift

Herbicide drift on a Redbud tree, Cercis canadensis. On the right I am holding a leaf that has escaped the herbicide damage. The distorted leaves in the background with wavy edges show herbicide injury.

Herbicide injury on Spreading Euonymus, Euonymus kiautschovicus. I am holding a leaf without herbicide injury.

These Tulip Tree (Liriiodendron) leaves show herbicide damage with yellow spots and distortion of the leaves.
