At a friend's place in CT. A bunch of his maples have leaves that are curling up and turning brown at the edges. The trees seem otherwise healthy. Has anyone seen the like?
Nope......I don't know where your friend lives or if he minds people stopping by......... Some leaves around here are turning brown but I think it may be a seasonal thing.
Ive not seen anything like it. Not every sugar maple on the farm is this way. But it is nearly the whole of every affected tree, not just a branch. Trees are pretty close to the same size.... Leaves turning brown in fall do the whole leaf at once, not just the outside edges...
It almost looks like leaf scortch. Except that leaf scortch is generally a branch, not a whole tree. I didn't ask it in the OP, but is there anything going around that's wide spread? Sca
While I was outside, I made notice of the maple trees here, saplings and mature trees. Mostly red maples. No sign of leaf distress. Some kind of localized environmental thing down there?
Kinda what im thinking. Its not lack of water, and with sandy soil, I doubt over watering is the issue. Looking at various blights and fungussses....nothing matches yet tho.
I'm seeing a lot of it near my work in Middletown, on the sugar maples. The red maples are looking sparse in a lot of areas too. I kind of assumed it was because of the early leaf-out this spring, followed by a cold snap. But I'm a simple firewood hack and not a dendrologist. I wouldn't doubt there might be a foreign fungus, nematode, etc. that could be attacking the maples. I've been on the lookout for spotted lanternflies but so far haven't seen any.
Can you post a pic? My app has the feature to tell you what's wrong with the plant, maybe it'll do a tree too.
Is it somewhat like the picture below? If it is, then it's most likely maple anthracnose. Anthracnose, Discula (Gloeosporium). This disease is widespread on maples, particularly Norway and sugar maples. Large irregular areas on sugar maple leaves turn reddish-brown, usually involving one or more lobes of the leaves. On Norway maples a purplish discoloration runs along the veins. On both, the fungus fruits abundantly in little pale pink masses. Petioles may also be attacked. From a distance, infected trees look scorched. Rake and dispose of fallen leaves to reduce the chance of infection in the following season and maintain vigor of the trees with adequate water during dry periods and fertilization in the spring. Since this disease is usually not a serious problem for the health of the trees, chemical controls are usually not necessary.
Yes it does look like that pic. Scorch Is what I was thinking. The Wood Wolverine soons I get a chance to get back to the farm I'll take a pic.
Eric Wanderweg I looked at maples in North haven, Durham, Middletown, Middlefield. I saw a couple trees with a limb or two with what looked like the same thing, but didnt see a whole tree affected. Eric, if you get a chance, the trackside diner in Middlefield is open again. Had a corn beef rueben that was awesome. Sca
It’s been a very wet summer here in Michigan. That typically means a good year for fungus like Anthracnose. I’ve seen a lot of it around, and have several clients that have been affected by it in its various forms. Most trees are perfectly capable of surviving a bout of it, but it is important to remove the affected leaves from the property after they have fallen.
