Why Isn't My Red Maple Red

If fall temperatures are too warm, then red leaf color is inhibited. Additionally, a sudden cold snap below freezing will reduce red fall foliage. Trees with red leaves may fail to turn red if the soil is too rich and overwatered.

How long does it take for a red maple to turn red?

While it’ll take time for it to reach maturity, it won’t stay a leafless stick forever! Some trees are slow growers (20-30 years to reach full size) and some are fast (10-15 years). The good news is that red maples grow at medium speed; in the tree world, this equals about 12-18 inches of height a year.

Why are my red maple leaves green?

Red-leaved plants get their color from a pigment called anthocyanin. Anthocyanin is often displayed in the fall as chlorophyll (the pigment responsible for the color green) breaks down. Anthocyanin absorbs blue-green wavelengths of color, and reflects red.
