Crepe Myrtle Yellow Leaves: Heat, Drought, or Nutrient Imbalance

12-Year-Old Tree Shedding Yellow Leaves, Fewer Blooms

Yellow leaves all over 40-ft tree. Sprinklers 40 min every other day. Hot, dry but recent rain. Panhandle FL.

Expert Analysis

If interior leaves, no spots → heat/dry stress. But yellowing all over suggests nutrient imbalance or insufficient deep watering for tree roots (lawn sprinklers wet surface only). Soil test via Extension (free). Scratch twigs for green tissue to confirm life.
