Q&A - What kind of tree is this? Most limbs are dying or dead. What can we do?
Question:
What kind of tree is this? Most limbs are dying or dead. What can we do?
Answer:
This is either a blue spruce or Colorado spruce. Certified Arborist Wes Hopper says spruce trees commonly get rhizosphaera needle cast or cytospora canker which are both fungal infections. The problems appear when the trees get stressed. The fungus can be treated with a fungicide. Also, Wes recommends keeping the tree watered and fertilized with a low nitrogen fertilizer. This is a northern tree and growing outside its natural habitat will be a cause of stress.
