Hardwood cuttings are a reliable method of propagating deciduous and evergreen trees such as Prunus incisa. Take cuttings mid-autumn to late winter, using current season’s growth. Cuttings taken early or late tend to root best. For evergreen cuttings the same principles apply but make sure you remove any leaves from the end of the shoot that will be inserted into growing medium.
Raising trees from hardwood cuttings (RHS, The Garden, December 2017, p.22):
- Cut shoots into sections 4-8 inches (10-20 cm) long with about 4 buds.
- Make a horizontal cut below a node at the base of each cutting, and a sloping cut away from a bud at the top.
- Dip each cutting into rooting gel or hormone, then insert cuttings, upper buds above the soil, into a 6 inch pot of loam-based composted mixed with grit.
- Place in a cold frame or unheated greenhouse.
- Cuttings will root better if the soil is improved with organic matter. Make a channel using a spade and fill in with sharp sand to improve drainage.
- Insert cuttings 2 inches apart.
For Roses & Currants Etc.
- Take hardwood cuttings of roses, red & white currant bushes…
- For red & white currant bushes, take cuttings 12 inches long; remove all buds except the top 3 or 4 to ensure bare stems.
- use 50/50 soil and grit
