[CANUFNET] Pruning Wound Treatment

[via CANUFNET]

It looks like two distinct stems with included bark, i.e. a separation between them.  Rot may not penetrate into the healthy tree at all from the cut one as it rots away.

The tree owner has sent me an image of the tree. Clearly there were two large trunks and the cut is near the base. Is the cut angled sufficiently to let water run off? 

Thank you again for you help. 


Cheers

  I received the following inquiry to the Master Gardener Forum and am hoping to tap your collective expertise to know what the current standard is for pruning wounds.

    "We just had a 2 foot diameter limb of our 100 year old silver maple removed. It has been cut on a slope nearly to the ground. It has been suggested that the cut surface should be capped with sheet metal rather than painted with tar or whatever is often used. My question is, do we need to do anything to it or just leave it to "heal" over."

  Thank you for your assistance.
