Can You Trim Branches on Maple Trees in the Summer
If you're trimming heavy tree limbs, you have to be extra conscientious not to impairment the bark or interfere with the tree's natural healing response.
Doing information technology correct is really no more than difficult than doing it wrong, especially if you think ahead to how much piece of work information technology would take to remove a dead tree!
Hither's how to cut large tree limbs in your yard in three simple steps.
How Trees Heal
The truth is, trees don't actually heal as we exercise. When yous cut off a tree branch, the tree forms a special callous tissue (like a scar) that covers over the wound to continue out illness and disuse.
That scarred part of the tree volition be there forever, sealed off so that the rest of the tree can keep growing. It's very of import to prune trees correctly and then that we don't interfere with this process – incorrect pruning volition leave the tree weak and vulnerable to disease.
In the top photo, you lot can encounter the evidence of several big pruning cuts. The bumps evidence well-healed pruning scars, virtually of them completely covered over.
The "donut" shaped scar is normal, too. The callous tissue grows from the outside edges toward the middle, so it'south still in the procedure of sealing over.
How to Cut a Tree Limb
Proper pruning of large tree limbs involves iii cuts:
- Cut #1, Notch Cut: Cut a small notch in the bottom of the limb, 2-3 feet abroad from the trunk, and about a quarter of the style through. This notch volition keep the bark from splitting when you make the next cut.
- Cut #2, Relief Cut: But outside the notch, make a relief cut completely through the co-operative. This removes the weight of the co-operative and then that yous can make your final cutting without the branch splitting and falling.
- Cut #3, Final Cutting: This is the one that matters! Your final cut should exist correct where the branch collar (that swollen bump) transitions to shine branch bark. Follow the slant of the branch collar. If y'all tin can't fit your saw into the crotch at the right angle, and so cut it from the bottom up.
Common Tree Trimming Mistakes
Cut the Branch Besides Curt: Nosotros used to think that branches should be cut off flush with the trunk – boy, were we ever incorrect! The branch collar is responsible for forming the scar tissue. If you lot cutting into the branch neckband, the tree will have a very difficult fourth dimension recovering. When yous run across rotten holes in tree trunks or seeping wounds, you're looking at the aftermath of cut off the co-operative collar.
Leaving the Co-operative Too Long: The branch neckband on the trunk tin can only do its job of assuasive the wound to heal if all of the branches that it has to cover over have been removed while leaving the branch collar itself intact. In the photo on the right, yous tin can see how the branch stubs that were left besides long are interfering with and actually preventing the healing process from taking place.
Failure to Brand the Relief Cuts: If you fail to make the relief cuts and remove nigh of the weight of the limb earlier trimming the branch back to the trunk, you run the risk of having the branch split up off. This can cause substantial damage to the trunk, equally seen in the photo at right. This can make the wound on the trunk susceptible to disease and insect infestation and take much longer to heal.
