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.

What's blooming? What's chewing on my trees? What's that bug? When is the last frost? We'll explore timely horticultural happenings and observations of Nature in this blog. For the most part, these observations will be made in Southeastern Pennsylvania... with occasional notes from afar.Penn State Extension has tremendous resources related to much of what will appear here. I'll link you to sites that will provide more in-depth information.
