Weeping Cherry Yellowing in Southern California Heat

Spring-planted weeping cherry in SoCal: leaves yellowing in extreme heat. Good drainage, 2" mulch. Not underwatered? Overwatered?

Water Reality Check

Lawn sprinklers deliver <<1"/week. Grass outcompetes tree. Extreme heat increases need.

Prescription

  1. Deep water: 1" every 4th day (pan method) until rain/cooling.
  2. Fertilize: 10-10-10 at 1 lb/inch trunk diameter.

Consistent deep moisture is the fix—not more frequent shallow watering.
