A clone is uniform material propagated from a single individual by vegetative means such as grafts, division or cuttings. For example, the Bartlett pear clone originated as a seedling and has been increased by asexual propagation since 1770. Back To Top Cutting Propagation Cutting propagation is the most common method of asexual propagation. It can include various types of cuttings such as stem cuttings, leaf cuttings, leaf-bud cuttings or root cuttings. Not all plants can be successfully propagated by cuttings, but the number that cannot seems to shrink each year as new techniques are used.
Most trees are difficult or impossible to propagate by cuttings.
Timing Propagation Cuttings may be successfully made at different times with plants such as forsythia or crape myrtle, while with some azaleas and lilacs there is only a very short time during the year when cuttings may be rooted. Softwood cuttings are difficult to root unless the plant can be kept from wilting by either misting the plant or by maintaining 100 percent relative humidity. Hardwood cuttings are stuck in late winter in a location where they can be kept watered in the summer. They will form roots as they begin to grow in the spring. Leafy hardwood cuttings are not as difficult to maintain as softwood cuttings but require more attention than deciduous hardwood cuttings.
