Can you advise what needs to be done for this tree

[HersheyBB]

I try to figure out if there is anything to make this tree healthier. (Thank you for commenting)

[Mick Dempsey]

Cherries do that a lot, I don’t know if it’s something to do with the graft.

I would just leave it be.

[Steve Bullman]

Those bulging columns of lighter bark is the tree doing what it can to fix itself. There’s nothing more to do on your part at this stage 

[HersheyBB]

Maybe making sure that there isn't any insect activity within..?

[Mick Dempsey]

As a general rule the insects are only interested in the already dead wood.

Someone might contradict me there with a greater knowledge.

 

People are often surprised at the very shot life span of ornamental cherries 25/30 years and they’re already in serious decline.

 

Plant another one nearby.

A simple help for that tree is mulch soil underneath to stabilise soil moisture ( inch or two of chip or gravel) after you have hand weeded it or used geotextile mat before putting chip on. The damage is already there but the canopy is vigourous and will keep feeding the tree growth, giving it a chance of staying ahead of that decay. K

Thank you very much for all advises.

Instead of geotextile and gravel, mulch it with a layer of brown cardboard topped with rotting seaweed (if you live near the beach).

Chop it down.

Cherries do that, I knocked one over a couple of weeks ago that was absolutely rooted inside and the crown was held on by what might as well have been polystyrene. Only a diddy one so no dramas. Wouldn’t want to find a larger tree in that state though, I wouldn’t know where to start [emoji23]
