rowan tree

Question

The leaves on my rowan are going yellow. It has only been planted about 6 months. What’s wrong?

Answer 1

This is still a fairly new planting, so it could be suffering from a bit of shock, likely heat stress. The roots have not had enough time to fully establish, making it more difficult for the tree to withstand the high summer temps. Newly planted trees also require lots of water, so you may want to up its irrigation some.
