Japanese Maple Not Turning Red
2 too much or not enough sun.
Japanese maple not turning red. Red japanese maples will tend to green a little more during the heat of summer especially if they only get filtered sun. Some do some don t. Direct morning sun with afternoon shade or filtered sun will provide for the darkest red color. Red japanese maples do appreciate a few hours daily of direct sun.
As a result the leaves can no longer produce chlorophyll which normally gives the leaves their bright green color. Perfect for adding year round color. Japanese maples stay small in size and are low maintenance trees. In autumn the leaves of sourwood sumacs dogwoods and some maples often turn red or purple like the brandywine maple.
But what is the reason when two seemingly identical trees act differently. Weather is the primary factor on why your maple tree leaves are not turning red in fall. Japanese maple s fall foliage appears dull and burnt not vibrant red. The tree may need more nitrogen or iron or just new mulch.
