How to Graft Crab Apple Trees

Overview

Commercial apple trees, such as crab apples, do not produce the same variety of seed as the fruit themselves. In order to ensure a new crab apple tree produces these delicious and tiny apples, a different form of propagation is required. Grafting is the process of combining a twig or branch of a crab apple tree with the branch or root of an established locally grown tree.

Step 1

Select young twigs from a crab apple tree that are roughly 6-8 inches in length. Cut them from the tree and place the cut end into a bucket of water.

Step 2

Prepare the stock branches by cutting them to a length of 12 to 18 inches in length. Cut a 2-inch-deep slice directly down the center of the branch for insertion of the scion.

Step 3

Cut the end of the scion so that it forms a 2-inch wedge at the bottom.

Step 4

Insert the wedge end of the scion into the cut on the stock branch.

Step 5

Wrap the entire graft with rubber electrician's tape. The rubber tape will stretch and eventually fall off as the graft heals and grows.
