New hemlock losing needles- advice?
The nursery planted a hemlock and supposedly used root stim. I follow instructions on care with watering etc. The weather has been hot but it is dropping needles. I can't call the store back as this was a replacement for the one last year that did not survive. Awaiting a tree service to inspect next week. Meantime should I put some fertizer around it? I do not see signs of insects.
