Our magnolia tree is losing leaves and turning brown all over. Last fall about 2-3 semi large branches were affected by a storm. There are black spots on the leaves. We can we do to help it?? See picture attached.
Unfortunately this looks like typical winter damage, as it warms up it may get slightly worse but then this summer the tree should recover, we are at the very northern end of the Southern Flowering Magnolia's range so occasionally they do sustain significant damage through the winter months.
