Clean debris from your garden knife and dip the blade in household disinfectant for five minutes to disinfect it, then rinse the blade with water before using. Wipe the blade with disinfectant and rinse with water before each cut you make to avoid spreading disease. Make an angled cut on the attached part of the branch, as close as possible to the break but into tissue that has not yet dried. Make a similar cut on the broken piece, angled in the opposite direction so the two pieces will match up when placed together. Ensure that the cambium layers of both pieces, located between the bark and the light-colored inner wood, touch when the pieces are placed together. Make a small notch at the bottom of each cut piece and press the pieces together, joining them at the notches. Wrap the break with grafting tape, ensuring the entire break is covered.
