Also question is, why are the ridges important in a branch collar?
The branch bark ridge is slightly raised bark between the branch and the trunk that extends in a line to each side of the trunk. When the branch collar is difficult to identify, the branch bark ridge can help us decide where to make our pruning cut.
Furthermore, what is a tree whorl? The terminal buds on trees such as pines, spruces and firs include a central bud surrounded by a whorl of side buds. Each of these becomes a new branch. The center bud grows upward as the leader or future trunk. The others spread out like spokes on a bicycle wheel, becoming the lateral branches.
Then, what is a lateral tree branch?
Lateral branches collectively created the full, rounded canopy of a tree. Scaffold branches are the main, muscular arms that grow off of the trunk. A lateral branch is any secondary branch that grows off of the main trunk or scaffolds; all scaffolds are lateral branches that were once thin young twigs on the trunk.
What does a branch collar look like?
A branch collar is the often visible swelling in a woody plant that forms at the base of a branch where it is attached to its parent branch or to the tree's trunk. The top of the branch collar consists of dense interlocking wood grain, which provides mechanical support to the branch attachment.
