Hello - new to forum, seeking help please! We live in New York City, have an old, large euonymous tree (I say tree b/c it's about 20 ft high - euonymous manhatten as far as I know) that was perfectly healthy until 1 week ago when it started dropping leaves like crazy. The leaves first turn from their normal bright, deep green to a pale yellow, have grayish tips on some and small brown spots on others, and fall off. I want to save the tree but also am concerned about other trees and my garden plants "catching" this. Can you tell me what it is? Am wondering if may be anthracnose or some sort of leaf spot? And what is the best control to save tree and keep it from spreading elsewhere?
Thanks so much,
e

Welcome!

Have you tried taking some leaves and photos to your Agricultural Extension office? Or your local (not BigBox) nursery? They might have better answers for you. They may be able to tell you of any diseases/fungus/pests that are effecting Euonymous in your area.

My only other thoughts: Has anything changed? Have you crawled under there and checked to see if the drip line/sprinkler is still working? Have you given it any fertilizer recently? (that doesn't mean you should run out and fertilize - never feed a plant that is struggling).

Thanks Daisy! That was an initial thought I had too, but unfortunately - this being Manhattan - I don't think there's an Agricultural Extension Office anywhere and the big box store employees...well, let's just say they know more about rodent extermination than anything related to plants :)

I haven't fertilized it (ever) or done anything different at all...I can't really check the roots though as they are buried underneath both my and my next door neighbors deck...in fact the tree trunk itself has completely woven itself into the fence.

We have had a pretty wet spring so far, so I'm wondering if it's more susceptible to a fungus because of that...but still not sure how to treat it/prevent it from spreading...

Thanks again!

Here in ga, our eunonymous will get a fungus, and then.... May as well take out the entire planting.
Hate it for you, but it sounds like an oppurtunity in disguise.... Time to look at some rhododendron or blueberry or something else nice that will give colour and or fruit.

Did you try Cornell, if they don't have someone there to answer your questions, they'll refer you to someone and it'll only take one phone call, not a whole morning -- there is agriculture in town, you know! Smiling Here's Brooklyn http://cce.cornell.edu/:

Just being anecdotal here, was it hurricane Irene, the hurricane before Sandy? I had a perfectly healthy and lovely hemlock tree, and right after that storm cleared, it looked weird to me, I couldn't put my finger on it, then it just started turning yellow and died -- turned out to be a parasite that came up from the south with the storm. Might be something similar with your tree, it's probably a combination of that and the fact that it's probably just too tired and constrained where it is. Shrug!

Thanks Garden10, didn't realize Cornell was down here! Smiling I would really rather do everything I can to try to save this tree rather than just take it out...it's been healthy til now, I want to give it at least give it a chance!

Thanks

They're in Manhattan, too, but their site didn't look like they pay that much attention -- good luck with it! Smiling
