If rapid multiplication is desired, the soft and growing shoots may be layered during the summer. This opera- tion is variously known as "summer," "her- baceous," "green" and "soft" layering.

Pot-layerage. shoots are sometimes layered in pots instead of in the earth ; and the same is often done with strawberries in the field, giving the "pot-grown plants" of the nursery- men. The French have "layering-pots,'' with a slot in the side (Fig. 33) for the insertion of the shoot. In one style of pot, the slot extends from the rim down the entire length of the side and half-way across the bottom (Fig. 36.) Pot-layering, circumposition, air-layering and Chinese layering are terms applied to the rooting of rigid stems by means of surrounding them, while in their natural position, with earth or moss, or similar material. The stem is wounded—commonly girdled—and a divided pot or box is placed about it and filled with earth (Fig. 34). The roots start from above the girdle, and when they have filled the pot the stem is severed, headed back, and planted. Pot-lay- ering is practiced almost exclusively in greenhouses, where it is possible to keep the earth uniformly moist. But even there it is advisable to wrap the pot in moss to check.
