Lacebark Elm Leaf Holes and Transplant Adjustment

Separating Two Issues

A 6-week-old 45-gallon lacebark elm in Central Texas shows:

1. Tiny holes in 20–30% of leaves (progressive, not sudden) → likely shot hole fungus (Wilsonomyces) or flea beetles.
2. Browning/curling on windy side → transplant shock + wind desiccation.

Targeted Approach

For holes: Apply Hi-Yield Copper Fungicide as precautionary shot hole treatment. Reapply in 7–10 days. Monitor—if new holes appear, retreat. Copper is safe, broad-spectrum.

For shock: Water 3×/week is appropriate for new tree in clay. Mulch 3 inches. Prune dead tips next Feb. New growth (30% of canopy) is excellent sign—tree is establishing.

Why Not Insecticide Yet

No insects seen; holes are progressive (fungal pattern). Copper covers fungal/bacterial causes. Avoid unnecessary chemicals on a recovering tree.
