Several of my cherry trees are pouring out sap from their trunks. It starts at ground level and goes about 8 feet up. Trying to figure out if we have a new invasive or what. The bigger trees 16"ish dbh and bigger seem unaffected. Some have huge pools of sap on the ground. I found a few other similar cases online but no answers.
Yes. I have that on several. Its jelly like stuff but it doesn't run down. It's only in spots of damage or disease.
Cant say that I have on black cherry. Wonder if big temperature fluctuations have something to do with it? I know wild cherry/choke cherry oozes jello like globs on wounds. Grossed me out as a kid.
Mention cherry syrup and all I think of is that nasty tasting "cherry flavored" cough medicine when I was a kid. Yuck!
I’m probably off base here, because I know nothing about cherry trees. But if I had to take a wild guess, I would think you may have some type of boring insect attacking your trees. That looks a lot like what happens when the pine beetles around here attack our pine trees. Here is a picture of a huge Limber Pine on my property, that got beetles in July of 23. I cut it down immediately, as pine beetles are a death sentence for a tree and spread to others quickly. I’m not sure what might be in your Cherries. Obviously not Pine beetles, but a similar looking effect in my opinion.
That's what I'm thinking. Hoping it's not some new invasive. I'm going to peel back some bark tomm and see if I can see any borer holes etc. With how much sap is coming from a few of these I feel like I'd notice an insect infestation but who knows.
Pretty sure that article lists the causes for it. One is bugs. My arborist friend also said Cytospora Canker can cause it.
I've seen black cherry do this but not to that degree. My peach trees would do that, usually after a heavy rain, usually out the branch tips and buds though, not the trunk. In the Spring. I'd be peeling some of those bark flakes off to see if there are boring holes. Although if they are boring in rather than out they are probably gonna be really tiny holes.
We had a few cherry trees that had that black globs on them when we moved to our house. One was in the yard and it was all over the ground and tree, the next spring it didn’t leaf out as well as some others and showed lots of small dead branches. It had already been marked for death as we were planning on expanding/opening up the yard. Had another one 14”-15” DBH that was 40’tall or so in our fruit tree area. I cut it down after some wind damage and noticed the very top was covered in the black globs as well. At the time I was blaming the sapsuckers as they were leaving rings of holes on all of the trees. They killed a couple basswood and two apple trees, I wanted to blame them for all of the tree damage that year. I’ve kept an eye out for it on the remaining cherry trees, but haven’t seen it in a few years.
