Q: I have 8 Dwarf Alberta Spruce that are about 7 feet tall...they have bad bagworm damage. I have sprayed them and Killed the bagworms.
Now what do I do about the dead parts? Some of them are about 40% defoliated. Should I trim out the dead limbs at the trunk ?
Thank you very much
However, it will take a very long time for the bare areas to fill in because the average growth rate for dwarf Alberta spruces is only 2-4" per year, usually closer to 2" than 4".
