Dying Flowering Plum Tree #870658

Asked May 29, 2024, 8:02 PM EDT

We have been enjoying this flower plum tree we planted 3 years ago. Over those years it has grown several feet and has been seemingly happy. This last February it flowered (see attached picture) although it did not produce as many as it has in the past. The tree now in May had no leaves and the branches are quite brittle and break off easily like they are dead (see attached pictures for tree and up close of the branches). We did apply Mr. Jimz about two weeks ago in efforts to give it some nutrition it naught be lacking. Curious to learn any insight of what could have happened or if this tree is salvageable. Thank you very much!

Brittle stems are dead stems. Why did it die? A tree fails to establish for a number of possible reasons. Possibly if you dig it, you’ll find an answer, but it is not always evident. Maybe you’ll see rotted roots, girdling roots, maybe twine left tied in the roots. Perhaps it was planted too deep, or over or under watered last summer?
This, EC 1438, is the OSU app/publication about choosing, planting and caring for new trees. Compare the recommendations to what you did and that might help you determine or make a good guess about your plum.
You know, as a last look at your photo, is there a deep trunk injury part way up? Is the tree alive below that? You’ll still want a new tree rather than growing a new top on this one, but knowing what happened is still a way to avoid a repeat.

Good morning, 

Thank you very much for your response. 

I tried attaching a more up close photo of the injury, but the file was too big. It does appear to be an injury, although, I don’t know when that happened or if we purchased the tree with it. How can I tell if the tree is alive below that? Still unsettling to not know why it would flower in February and then not produce leaves come the spring. 

Hope you’re enjoying the sunshine!

Scratch the bark a bit to see if moist and alive.
Plants will form the flower cells in the fall, and a dying plant might have just enough energy in the roots to flower. It is disconcerting, but not unusual.
