Mugo pine disease
Two of our mugo pines have needles that are yellowing and turning brown. I'm afraid that I've lost the two plants already. I notice what seems to be white fungal growth on all the needles about 1/2 inch from the attachment to the branch. Is this what killed the pines or just an opportunistic fungus attacking an already compromised plant? Does anyone have any idea what might have killed the pine in the first place if not the fungus? There are no signs of worms or other predation. I don't want to lose any more pine that we have in the yard. Thanks for any help.
