15+ ft red maple in Jacksonville, FL green before 10-day trip; returned to brown falling leaves. 10x3 inch dead wood split at base (assumed termites). Hot with daily rain/irrigation.
Split with dead wood = internal decay, long-standing. Summer heat + possible soil moisture decline strained foliage, causing defoliation. Twigs show green = potential releaf if moisture restored.
No treatment for decay—progressive. Water/fertilize to prolong life. Eventually fails in wind/ice storm. Consider replacement. Prevent mower/trimmer damage to bark on new trees.
