Dallas live oaks (one huge, one small) show brown leaf clusters on north-facing tops since late May. Trees cut back last year; power lines on north edge. Similar symptoms in alley trees.
If rainfall inadequate, old live oaks shed leaf tips to conserve water. Install soaker hose at base for slow, deep watering. Dead tips won't regrow; new growth should be normal.
