Just planted red maple in shock
A month ago we planted a 12' red maple 'October Glory' tree purchased from a local nursery. Due to lack of experience, during planting we probably have exposed the root to the sun and wind for far too long. The leaves have changed color a few days after the planting:
The leaves looked much worse (more red) about a week ago, but has turned back green a little recently. No leaves have dropped. The newer, small leaves are still green as normal. Leaves that are shaded by others look significantly greener. Some additional information:
- The tree sits in the backyard that faces northwest.
- Full sun. Right after planting, we had a week of hot, windy days. Last week was also very hot.
- Soil is heavy clay with miserable drainage. For the planting hole, the composition was 7:3 of clay:black soil/garden earth. We planted it shallow so the tree's trunk flare is 4" above the ground. We also covered the 3' hole with 4" of red cedar mulch.
Just 25m from this red maple, there was a ~15' red maple on public property suffering from mild (~20%) chlorosis probably as a result of the heavy clay.
The nursery told us to keep waiting as the tree is shocked. We wonder what we can do to help the tree. Thanks.
