a need is disclosed. This can be determined by pressing a portion of the sand in the flat between the fingers. If the sand is moist, no water is needed, if not, water lightly with a fine spray.

It is recommended that the frames be aired once a week on a cool day, or early in the morning, for approximately one to two hours to prevent any danger of fungus. However, never open a frame on a very hot day with low humidity.

When the temperature reaches 75 degrees a covering of cheese cloth should be placed over the frame, and on a very hot day of 90 degrees or more a double covering may be advisable. Where the frames are in the full sun, a heavy covering such as burlap should be used.

Removal from Frame: In summer, cuttings will root in approximately four months, and in winter in approximately six months in an unheated frame. However, some varieties such as Alba Plena will take much longer.

To determine whether the cuttings are ready to remove and pot, loosen an occasional cutting throughout the flat. If the average root formation is 2/3 or better, remove and transfer to a 2 to 21 inch pot, with a soil mixture of ¼ sandy loam and ¾ peat moss. If the average root formation is less than 2/3 leave the cuttings in the frame. Cuttings taken from the flat with a good white callus, but no roots, can be replaced in a flat and returned to the frame. However, if the callus or the tip of the cutting is black, throw it away. The newly potted cuttings should be thoroughly watered with a solution of B-1 and protected from the hot sun for a few days, after which they can be exposed to the sun under lath or trees.
