Improving Fall Color on Maples in Eastern Oklahoma

Poor fall color (yellow/brown, early drop) often stems from excess shade or nitrogen. Maples in partial shade color earlier. High nitrogen prolongs green chlorophyll, masking pigments.

Fertilize with 10-10-10 at 1 lb per inch of trunk diameter in spring and midsummer. Test soil via your county Extension office—pH or micronutrient imbalances may also affect color. Full sun and balanced nutrition maximize autumn display.
