Wilson® BLOCK OUT Pruning Paint

Pruning is an important part of protecting your property: to remove dangerous overhanging limbs; to get rid of diseased branches; and to shape shrubs and trees into pleasing forms. In previous generations, it had been common practice to apply pruning paint to virtually every cut, on the premise that this would help keep out noxious insects and fungi. Recent research has shown this may not be as true as once thought, and in fact, pruning paint can interfere with natural healing and may help seal in rot.

However, our pruning paint has real value in specific situations. For example, in protecting trees such as oaks and elms that are extremely susceptible to fungi carried by certain beetles. Or fruit trees that are vulnerable to bacterial infections. Not to mention for trees that have suffered from the actions of Mother Nature, equipment, kids or animals, leaving large areas debarked. These areas are so large that a proper callous can never be created, leaving them vulnerable to infestations and dry rot. In these cases, pruning paint can be extremely helpful in keeping the exposed wood from drying out and cracking.
