Coat the cut surface of the tip end of the scion with a protectant such as white glue, orange shellac or tree healing paint to prevent it from drying out (figure 11).
Loosely cover the taped area with a piece of household aluminum foil. This reflects sunlight and maintains a lower temperature at the graft union (figure 12).
Cut off the corner of a pint-size or quart-size polyethylene bag (freezer type) and carefully slip it down over the graft union with the scion protruding though a hole in the bag. Be careful not to knock the buds off the scion while positioning the bag (figure 13). Tie the cut corner of the polyethylene bag to the scion just above the aluminum foil wrap but below the first bud on the scion. Then tie the lower end of the bag at the bottom edge of the aluminum foil. (Do not leave exposed wood inside the polyethylene bag.) These ties may be made with any material that will stretch, such as plastic budding tape or rubber bands.
