Help needed w/ sick magnolia (yellow leaves)
Hello - First of all, thank you to anyone who can help me with my question! This is my first spring in my first house, and one of my favorite things about the house was the large Southern Magnolia right in the backyard.
Well - the leaves have started turning yellow and falling off - significant loss of leaves. Also, there are brownish/black spots on the underneath of the leaves. There is some new growth at the very ends of each of the limbs - but overall, the tree is looking very sick. I've been trying to give it extra water over the past 2 weeks, and have fertilized with miracle-acid once. Any idea what is wrong with the tree?
