If the needles are healthy, you don’t have to remove them.Quick question, Assume I follow the recommendation here.
Copper + Daconil (alternate every week) + Systemic (Spring and another after 2 weeks after decandle).
Do I need to remove "All" the needle with needle cast ? (1-2 year needle?).
Or I dont need to remove all since all the new needle have protection already?
thanks

On my pines, I tend to remove the old needles because it looks tidier. And it opens up the canopy for sunlight.
