Shamel Ash Severe Bark Loss: Fertilize or Remove?

Two Shamel ash (30 ft & 20 ft) lost leaves, then bark peeled off in a storm. One has 16″ trunk, other 12″.

Assessment

• If >75% foliage dead & bark loose full circumference → tree is failing.
• If some green remains → fertilize (1 lb 10-10-10 per inch DBH) now & spring.
• Wait until spring leaf-out to decide.

Likely Outcome

Bark separation full-circle = girdled = death. These trees are prone to sudden decline in desert climates. Plan for removal if no spring recovery.
