Success is also correlated to the amount of wood that is still attached -- if a thin strip of bark is all that is hanging on, chances of survival are low. Wound Dressings Research indicates that wound dressings materials such as tar or paint do not prevent decay and may even interfere with wound closure.
Be on the alert for downed power lines and dangerous hanging branches that look like they're ready to fall. For smaller branches, follow the pruning guidelines shown in the illustration so that you make clean cuts in the right places, helping the tree to recover faster see Illustration D1.
