Q.crape myrtle leaves turn yellow
What would cause healthy crape myrtle leaves to turn yellow and fall off? Very healthy tree..but leaves turning yellow and falling off.
Yellowing leaves generally is a signal of watering issues. Either to much or to little.
When the summer heat arrives the tree may be losing to much moisture.
Mulching with 2 to 3 inches of hardwood mulch can help with moisture loss.
Add watering a couple of times a week during dry spells and high temperatures.
Stressed trees can sometimes invite disease or insects. Watch for these issues.
