How A Tree Heals

This clip from our how-to video Prune Like a Pro shows the way a tree heals a large wound over nearly eight years of observation. You can see the formation and growth of the cambium collar, which is how the tree closes off the wound and protects itself from insects, bacteria. fungi, water, and air, which can damage or kill the tree.

TreeCare has developed revolutionary new products to help your tree heal wounds that in the past could have been fatal.

Tree Guard and Tree Heal, our unique formulas of orange oil and orange oil/beeswax kill potentially hazardous organisms before they can penetrate the tree’s defense sys-tem, and seal the wound against water, which might otherwise provide an environment for decay, and air, which can kill the tree if it enters the vascular system. Unlike tar based sealants of the past, Knowlton’s TreeHeal treatments allow the wound to breathe, which is critical to good healing.

After years of testing in the field, we believe Knowlton’s TreeHeal products are the only reliable way to protect your trees’ wounds. When you watch this demonstration, we think you’ll agree, there is no better way to send your trees into the future.
