Aesculus flava problems — and how to fix them
Aesculus flava (Aesculus flava) 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.
Leaf scorch / blotch
Leaf margins brown in hot, dry, windy weather or from Guignardia leaf blotch; both worsen on dry soils. Mulch and water young trees, and rake up fallen infected leaves to reduce fungal carryover.
Toxic nut drop
The smooth nuts and their husks are poisonous and litter the ground in autumn. Position away from lawns, paths and pet areas, and clear fallen nuts where dogs or children may pick them up.
Early leaf drop
In drought-stressed summers the tree may shed leaves prematurely as a survival response. It is rarely fatal; deep watering and a moisture-retentive mulch prevent recurrence.
Needs space
Often planted too close to buildings or smaller trees; the broad crown and heavy surface roots crowd neighbours. Allow at least 8-10 m clearance at planting.

Most aesculus flava issues are care-mismatch, not bad luck. Dial in the basics:
