1. Cuttings: Facilities: A cold frame is usually the most practical way to root cuttings, and consists of an airtight frame of the following dimensions Six feet wide and length desired; 18 to 24 inches high at the back, sloping to 12 to 18 inches at the front. The top is covered with a glass sash. The frame can be placed on the ground and the bottom should be covered with two inches of gravel to aid drainage and topped with 2 inches of sand to hold moisture and build up humidity. On top of the sand 1 by 1-inch garden stakes should be criss-crossed so that the flats will sit above the sand for better drainage and circulation of air. The frame should face south and be placed under lath or trees where filtered sunlight is available, as the protective care required when they are in the full sun, is excessive. If desired a heating device can be placed in the frame with a regulated temperature of 65 degrees to 70 degrees. Also, if available, cuttings, can be made on a bench in a glass house.
Bedding plant flats make the best containers for planting. Wash the flats and fill all cracks with sphagnum moss. Then fill the flat with thoroughly washed sand, and pack tight. Peat moss is sometimes mixed with the sand to be placedpage 84
