Why the bark is splitting?
About a month a ago, while pruning the lower branches of this conifer, I think the gardener managed to damage the bark (presumably when cutting and pulling the branch out).
It is looking like as shown in photo. Do I need to apply anything to prevent infection or cover it up with something? I'm based in London, UK and it has been raining like forever since last November! Not sure whether too much water would prevent the wound to heal properly?
Any suggestions are appreciated!
