Cuttings are pieces of plant material like stems, leaves, or roots that are used to propagate new plants. These cuttings are placed in conditions with appropriate temperature, humidity, light, and nutrients to develop roots and grow into full plants. There are different types of cuttings including stem tip cuttings, stem section cuttings, leaf cuttings, and root cuttings. Stem section cuttings can be further categorized as softwood cuttings taken from new, succulent growth, semi-hardwood cuttings from partially woody shoots, and hardwood cuttings from mature, woody stems. Proper tools and environment are needed for successful rooting of each cutting type.

- 2. CUTTINGS • Cuttings are pieces of vegetative material obtained from plant organs- stem ,leaf, or root. • These tissues are nursed under appropriate conditions temperature, humidity, light, moisture, and nutrients to develop into full-fledged plants • Place stem and leaf cuttings in bright, indirect light.
- 6. STEM-TIP(TERMINAL) CUTTINGS In stem-tip cutting the tip of the stem is cut and used to produce a seedling. The piece cut is about 3 inches long and has leaves Terminal cuttings may be obtained from herbaceous, softwood, semi softwood, and hardwood plants The cut may be made either the node or inter- node of the stem .
- 7. STEM- SECTION CUTTINGS Softwood cuttings Semi-hardwood cuttings Hardwood cuttings Deciduous wood Narrow- Leaved Evergreens Herbaceous
- 10. Softwood cutting • Softwood cuttings are prepared from soft, succulent, new growth of woody plants, just as it begins to harden, shoots are suitable for making them when they can be snapped easily when bent and when they still have a gradation of leaf size • For most woody plants, this stage occurs in May ,June ,or July. The soft shoots are tender, and extra care must be taken to keep them from drying out.
- 11. Semi –hardwood cuttings When cuttings are taken from partially mature, slightly woody shoots, they are known as semi-hardwood cuttings. Semi-hardwood cuttings are also succulent and tender in nature, and are usually made from growing terminal shoots. Shoots that snap clean when broken are considered to be ideal for semi-hardwood cuttings.
- 12. Semi-hardwood cuttings Large terminal leaves are sometimes trimmed to some extent to prevent wilting . The basal cut is given just below a node. Best result are obtained when the cuttings are collected during the cooler part of the day, preferably in the morning, while the material remains turgid.
- 16. HARDWOODCUTTINGS DECIDUOUS WOOD From leafless plant • Deciduous hardwood cuttings are made from plant part that are more hardened, woody, and mature enough to spring back when bent and released. • They are taken before the plants produce a flush of spring growth.
- 17. Deciduous wood • They are taken before the plants produce a flush of spring growth, in early spring growth, or late winter • The material are thus obtained from the previous summer’s growth . • They are best rooted in a well –drained, sandy medium • Some fruits (e. g., grape, fig, and etc..,),deciduous shrubs(e. g., rose, etc.. )
- 18. Narrow –leaved evergreens Conifers, narrow leaf evergreens, are commonly propagated by hardwood cuttings obtained from plants in early winter. These cuttings should have needles on the upper part . Conifer cuttings root slowly, sometimes requiring month to produce adequate rooting.
- 19. Narrow-leaved evergreen The preferable rooting environment is cool and humid . Sometimes a cold frame with high light intensity can be used to accelerate the rooting process. Example of plants in this category are juniper, hemlock, pine
- 21. Herbaceous cuttings • Herbaceous cuttings are made from non-woody, herbaceous plant such as coleus chrysanthemums, and dahlia. • A3 –to-5-inch piece of stem is cut from the parent plant. • The leaves on the lower one-third to one- half of the stem are removed. • A high percentage of the cuttings root, and they do so quickly.
