Have 2 large hollies but one has been loosing many leaves this spring and continues to drop them while the other does not. Ants are all over the tree as well. the tree is getting crowded by other bushes on one side. The fallen leaves are hindering the plants under it. Would appreciate any thoughts on how to help out the old girl.
Need to find out why before you can take measures. More information needed to determine cause. Down here you could try Cooperative Extension, don't know what is available up there.
