To seal or not to seal

I have a flowering cherry Tree which has two trunks, it was in the garden when we moved into the house some years ago. I want to cut one of the trunks off to get more light in the area. Question is do I seal after cutting it or leave it to nature to heal.

 

I think its recommended to summer prune and not seal.
But that is just off the top of my head.

 

Thanks for replies I maybe keep an eye on it see how it gets on, any signs of it being ill I will give it
'Intensive care' .

 

Do not be tempted to do this now. Wait until late winter, when the tree is dormant. Then cut away to your hearts content, and there is no need to seal.

 

Well I got round to looking it up.
And the RHS seem to say sealing is good.

And prune in summer to avoid silver leaf, I knew I'd come across summer pruning somewhere.

good information from rhs thanks glad you remembered it, Isn't it wonderful what our memory box can cough up when we need it, wish mine would cough up names of plants that labels have disappeared from

 

I have a problem with that one, my spouse is clueless he's very good at digging up weeds but they're usually my plants, he don't know the difference

 

Sounds like me then.

 

For me no seal. And prune only in summer so wouldnt prune now
It must be confusing though and the accepted "wisdom" seems to change from time to time. Logically, for me, summer pruning and naturally quick healing open wounds

 

@Joyce Esau , you have the classic GC answer to your question . Yes , No , Maybe

 

Definitely clear from me.....no seal
