Japanese Maple- Coloring
Q: I have a five year old Japanese maple. When I set it out the leaves were a dark crimson red color. For the last few years the leaves have been green all spring and summer. Is there any way to get the crimson color back?
A: Japanese maple leaf color can be affected by too much heat, too much shade, too much sun and too little water. Although I see Japanese maples growing in full sunshine, they color up better and seem happier when given direct morning sunshine followed by shade after 2:00 p.m.
Consider the factors I mentioned and then make a hard decision: move it or enjoy where it is.
