Simple layers (Fig. 55) are made by bending and covering the branches with more or less soil. In general, a shallow and short trench or a small hole is made in the earth and the branch pegged or weighted down in it prior to being covered with soil to the depth of two or three inches but with 6 to 12 inches of the extremit}- of the shoot uncovered to draw sap and elaborate plan

To hasten root formation the stems are often wounded. FIG. 55—LAYERING OF VARIOUS KINDS A, ordinary layering; a, layering pegs; B, continuous layer; C, serpentine layer (alternate nodes pegged down). D, mound or stool layer. at the points to be covered, ^^'ounding may be done by scraping the bark or cutting through the cambium layer on the lower side of the branch below the bud or shoot to grow, or it may be by severely twisting the branch at this point. Hacking with a knife near the node is also often done. These woundings tend to form adventitious buds on which root growth in asexual propagation depends. So man}' species and varieties of shrubs may be prop- agated by simple laj'ering that it seems probable an}' woody plant capable of being bent to the earth can be thus propagated. (Currant, gooseberry, golden bell.) Black raspberry canes and shoots cannot be made to root well when covered at more than their tips. (Fig. 56.) When the tips are about ready to take root they.
