Silver Birch

My friend decided to prune a Silver Birch, out of the branches where h
cut is now a steady flow of what appears to be water. Does anyone kno why or what this is. He says the ground is quite wet, but no especially so. Is there anything he needs to do to stop the wate flowing out the end of cut branch

it's sap. the tree is 'bleeding'. it will stop when the tree is able to grow scar tissue over the pruning wounds. how long that takes depends on the tree, the time of year, etc. lee

Your friend just mistimed the pruning, birch and maple would be better off pruned late season (August) because as you have witnessed they bleed. Do not apply anything to the wound.

At this time of year the sap is rising, so that is what your friend i seeing. Probably best to leave it as is, any treatment of the cuts is likely t seal in disease
