Answer: Japanese maples need protection from hot afternoon sunshine or the leaf margins will look scorched. They prefer to grow in the filtered shade of larger trees, but full shade in the afternoon is acceptable, as well. Japanese maples provide all-year interest. Young spring growth is glowing red; summer leaves are soft green; fall foliage is scarlet, orange, or yellow. The color change you mention is perfectly normal for a Japanese maple. To lessen transplant shock, wait until this fall to move your tree to a more protected spot.
