These are the tools you should have already embraced.
Adelgids. Kinda like a fuzzy aphid from asia. Not a crazy plant killer; but, a eyesore. Although, it could be spidermites… shake the needles over a white sheet of paper and look for teeny specs moving… Treatment is the same.
If your a rabid eco-ist, insecticial soaps; or pluck n crush. Your favorite bug spray should work, with a drop of dish soap for dispersion. Otherwise, NUKE em with acephate. It is a folier and can be absorbed through the roots. It spreads inside the plant–systemic. Be aware, it will kill honeybees if used on flowering plants… It’s not real good for you either… safety first.
Watch the videos. Do your research.
The surface treatment videos will answer that question. Used with organic fertilizer, it grows moss real well. The trees and microbiom will be happier! It does keep the pot wetter. Just don’t over water, the pines especislly.
