5 for 1 - purchase plants for early January finish 5 plants for each one purchased. 12 for 1 - purchase plants early November finish 12 plants for each one purchased. Small cuttings 1-2 inches in length can be spaced about 2 x 2 inches. Larger cuttings will need more space. Generally flower buds must be removed during propagation to prevent botrytis problems.
Direct rooting uses more space, but reduces transplant time and transplant shock.
Media temperature 70-75. Reduce light by a layer of cheese cloth until cuttings become turgid. May need to reduce sunlight at end of crop to prevent sunburn on flowers. Carbon dioxide is not generally used during propagation. Generally put at finished spacing at time of potting up or moving from propagation.
