A very common mistake in training trees is to allow narrow crotch angles to form. If the fork of a tree is too sharp or narrow, bark will be trapped between the two limbs causing a very weak connection. Along comes snow, wind or a heavy fruit load and the crotch will tear apart resulting in the loss of an entire limb. In this video I show a bark inclusion on a broken Madrone tree and then demonstrate several ways to train against or fix narrow branch angles. This is a serious problem that should be understood by anyone training fruit trees. A little attention early on will insure the tree grows well for the rest of it's life.
