Can you feel how much easier it is to pull the codominant stems apart? Why is that? What does that say about pruning strategies? 2) Find a tree about 5 inches trunk diameter that you can mutilate. Remove a small branch that is less than half the trunk diameter from the trunk making an appropriate removal cut. Remove a codominant stem making an appropriate reduction cut. One year later remove about a six-inch-long section from the trunk centered on each crotch. , split the sample through the pith of the stem and trunk with a chisel).

Except for epicormic sprouts that form from superficial latent buds in the bark, a branch that is small compared to the trunk is usually deeply embedded in the trunk. That is what gives the branch union its strength. This deep embedding occurs when wood from the branch in the spring grows partially over last year’s trunk tissue at the base of the branch (Figure 3-8 left). Then the trunk wood on some trees overlaps the branch base later in the growing season. The annual overlapping of wood results in a strong union.

Twice as much load (56 kg) was required to split the small branch from the trunk than to separate the upper codominant stems (27 kg). Codominant stems can be fairly well secured to a tree provided there is no included bark in the crotch (Figure 3-5). One of the main objectives of pruning trees is to prevent included bark from forming, or to reduce growth rate on branches with included bark in the union. Codominant stems and large branches with included bark may be the single most dangerous condition (other than decayed roots) posed by trees in urban landscapes.
