It's June... why are my tree's leaves falling?

No, it's not normal for tree leaves to begin falling in late Spring.... but it happens. If you've been observing sycamore trees lately you'll see what I mean. A fungal leaf disease called anthracnose causes stem cankers and leaf disease that results in premature leaf drop.



Should you be concerned? Think about it. Those big old sycamore trees have probably had anthracnose many times. They survived it. So although it looks bad now, obviously they can tolerate this. Why? When summer temperatures arrive the disease stops and trees re-foliate. Certainly the trees have been stressed but they usually recover.
