Heat-Stressed Japanese Maple: Patience & Shade May Save It

Leaving a ‘Sango Kaku’ Japanese maple in a hot car caused leaf scorch. The tree may recover if the cambium (living layer under bark) survived.

Recovery Plan

Plant in bright shade (no afternoon sun).
Water weekly—deep soak, not frequent sprinkles.
Do not fertilize or prune this year.
Wait. If green leaves appear, it’s alive. Full recovery may take a season.

Japanese maples are resilient; many bounce back from severe heat stress with time and gentle care.
