Blue Spruce Top Tip died

Asked July 6, 2017, 6:21 AM EDT

I cut off the tip and the row of branches below the dead part. There was a larvae in the center of the dead tip. What can I do to prevent further damage? Tree is about 10 feet tall. Will it start a new leader at the top? It is in full sun..

Based on your description you may be dealing with a type of weevil, possibly the white pine weevil but we cannot say for sure. Control involves pruning the affected terminals back to healthy tissue and discard in the trash. No sprays are recommended. You will have to select and train a new leader.

Keep the tree well watered during dry periods and make sure mulch is no thicker than several inches and away from the base of the trunk. Monitor the health of the tree.
