Troubleshooting
Full Moon Maple problems — and how to fix them
Full Moon Maple (Acer shirasawanum 'Aureum') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Sun scorch and bleaching
The golden leaves burn and fade in strong sun. Plant in dappled shade with shelter from wind, and keep soil evenly moist to reduce stress.
Verticillium wilt
Soil-borne fungal disease causing branch dieback and wood streaking. Prune out infected limbs, disinfect tools, and avoid replanting maples in affected soil.
Slow establishment
Grafted full moon maples are slow and resent root disturbance. Plant in autumn or spring, water consistently, and be patient through the first few seasons.
Leaf-edge browning in containers
Pots dry and overheat faster than open ground, browning the pale foliage. Use a large container, mulch the surface, and protect roots from extreme heat and freezing.
Prevent full moon maple problems before they start
Most full moon maple issues are care-mismatch, not bad luck. Dial in the basics:
