Simple layering is a proven means of propagating climbing roses, forsythia, grapes, wisteria, pyracantha and many other plants. Plants with a trailing or vining growth habit can typically be propagated this way. Choose a low branch and injure the bark about 1/2 to 1 inch along the stem and 8 to 15 inches back from the tip. Cover the injured area of the stem and anchor with a wire shaped like a hairpin. Rocks or bricks could also be used to hold the stem in place. Do not let the soil dry out. Before new growth begins in spring is the best time to do a simple layer, since the injured portion develops roots during summer. Spring layers can be cut from the parent and planted in early fall or left until the following spring.
