One of the most important aspects of cloning by taking cuttings is selecting an appropriate donor plant. The idea is to select a plant variety that has the traits a grower wishes to replicate. However, it is also very important to select a donor plant that is in good health. If the donor plant has diseases, pest insects, or other pathogens chances are good that any clones taken from that plant will have those same problems. Always inspect a potential donor plant carefully before taking cuttings.
Once a donor plant is selected, it can be prepared for the cloning procedure. One technique that helps to increase cloning success rates is to limit the donor plant’s exposure to intense light for 24 hour prior to taking clones. The plant does not need to be moved into complete darkness. Moving the donor plant to a shaded section of the greenhouse or removing the plant from direct horticultural lighting will help to prepare the plant for cloning purposes. It is also important that the donor plant is not showing any signs of environmental stresses. In other words, it is not wise to take clones from a donor plant that is wilted due to heat or lack of water. If possible, try to make sure the donor plant is at the highest level of health before taking clones.
