The prepared cutting should be stuck into the medium up to the remaining leaves. Water thoroughly to settle the medium around the base of the cutting. The propagation medium should never dry out during rooting. Also, avoid excessive watering, which results in poor aeration and death of new roots. Since cuttings don't have a root system, high humidity must be maintained.
Low humidity allows wilting, scorch, leaf drop or death.
Enclosures help maintain high humidity. Monitor the plastic bags for condensate, and water the medium when condensate disappears. Never place plastic-enclosed containers in direct sunlight, because excessive heat will build up. For rooting large numbers of cuttings, use coldframes, hotbeds or greenhouses.
