Curly Willow Summer Leaf Drop: Water, Borers, or Shade Competition?

Most Likely: Drought Stress

Willows need constant moisture. Weekly 1-inch deep watering often stops leaf drop.

Inspect trunk for holes + frass. If found, spray Merit on trunk.

Willow roots outcompete nearby plants for water. Water the whole bed deeply, or relocate shade plants.
