Q.Little Leaf Linden Dryness Condition
The lower 1/4th of the branches, on the southern side (sun exposure), is very dry and browning, compared to the rest of this healthy 40′ Linden. Many Little internal twigs in this area are dead and dropping. The last 2 1/2 months in our Cleveland area have been dryer and warmer than normal. Any ideas for treatment? D. Z.

Are you providing supplemental water to your tree? If not, that should help. Also prune out any dead or dying branches and twigs. Check the leaves for fungal leaf spots as well as any pests.
