Shoots or bark do better when soaked for 24 hours prior to using. The extract obtained from the crushing of leaves and bulbs of coco-grass (Cyperus rotundus) is used as an excellent rooting of cuttings and seedlings of various plant species. Honey, though it does not contain any plant hormones, can also aid in rooting success through its natural antiseptic and antifungal properties. Cinnamon or an Aspirin tablet in water can also aid the rooting process. Types Many vegetative parts of a plant can be used. The most common methods are: Stem cuttings, in which a piece of stem is part buried in the soil, including at least one leaf node. The cutting is able to produce new roots, usually at the node. Root cuttings, in which a section of root is buried just below the soil surface, and produces new shoots. Scion cuttings are used in grafting. Leaf cuttings, in which a leaf is placed on moist soil. These have to develop both new stems and new roots. Some leaves will produce one plant at the base of the leaf. In some species, multiple new plants can be produced at many places on one leaf, and these can be induced by cutting the leaf veins. The leaf cutting method is commonly used with succulents. Although some species, such as willow, blackberry and pelargoniums can be grown simply by placing a cutting into moist ground, the majority of species require more attention. Most species require humid, warm, partially shaded conditions to strike, thus requiring the approach above to be followed. Particularly difficult species may need cool air above and warm soil. In addition, with many more difficult cuttings, one should use the type of cutting that has the most chance of success with that particular plant species. Improving results There are ways of improving the growth of stem cutting propagations. Intensifying light allows cuttings to root and sprout faster, though the heat thus generated could cause the propagation material distress. Azalea cuttings can be mildly heated in water to disinfect it from the fungus pathogen Rhizoctonia, and this could potentially be used for other plants. Soil Depending on the type of cutting (i.e. tree, shrub, succulent, cacti) different potting soil mixes can be used. Many commercial companies sell medium specifically for growing cuttings. Air and soil humidity Although several options can be used here, usually plastic is used to cover
