2. CULM It is used to describe the bamboo shoot itself. Each culm segment begins and ends with a solid joint called a node . The segment between nodes are called internodes .

3. Is the underground part of a bamboo stem (culm). However, rhizomes are not roots. RHIZOME

4. OFFSETS Are short, lateral shoots bearing clustered leaves at the tips and are capable of taking roots as plant daughter.

5. BAMBOO PROPAGATION

6. Any form of asexual reproduction occurring in plants in which a new plant from fragment of the parent plant or a specialized reproductive structure VEGETATIVE REPRODUCTION

7. Select culms from a healthy plant that is more or less two years of age; Cut the culms with atleast two nodes that has live dormant bud atleast 4 inches above the second node. Immediately soak the cut culm in a clean water to prevent dehydration During sunny days it is better to collect propagating materials in the morning when the culm is rehydrated; This can be done to bamboo species such as buddha belly, machiko bamboo, giant kawayan , killing and other species with similar culm structure. CULM CUTTINGS

9. Select branches from healthy plant that is more or less two years of age. Detach the branches from the culm then cut the branches leaving 2-3 nodes with live buds; It does not require a long branch cutting to propagate. Leave atleast 3-4 inches above the second node; Immediately soak the cuttings in clean water to prevent dehydration; Cutting with or without roots can be propagated from selected species such as killing, buddha belly, bayog and variegated bamboo. However, higher percentage of survival can be attained if the cuttings have roots; Some species such as the giant bamboo, machiko and spiny bamboo do not survive when propagation is done during the month of November to February; In both cases, soak cuttings in clean water for 24 hours; To facilitate rooting of the cuttings, a rooting hormone should be used. BRANCH CUTTINGS

11. There are bamboo species that can be propagated using rhizome. These species are those that have thin culm, e.g. bolo.; Dig the rhizome and plant them in a prepared container; When the rhizomes have developed roots and the shoots emerged, bring them out and cut them such that every shoot with roots will be propagated as an individual plant; Note: Bolo can also be propagated by using the young culms. The best age is approximately 6 months to one year; dig the culm, and cut it above the second node. Be sure that the roots are not detached. Plant immediately in a prepared pots. RHIZOME CUTTINGS

13. PREPARATION OF SOIL MEDIUM AND PLANTING

14. A good soil medium should consist a mixture of: One part vermi compost One part alluvial soil 2 parts of carbonized rice hull (CRH) (1:1:2) Mix the soil media thoroughly and pack in a desired size of polyethylene bag; Fill the bags up to ¾ and plant the collected cuttings/rhizomes; Cover one node with soil and press gently; Water the base in order for the soil to settle and adhere to the base of the cuttings PREPARATION OF SOIL MEDIUM AND PLANTING

15. POTTED CUTTINGS

16. In case when there is no nursery, place the propagated plants in a partially shaded area or provide a temporary shade; Direct exposure to full sunlight can harm the propagated cuttings that caused lower survival rate; Watering should be done as the need arise. PREPARATION OF SOIL MEDIUM AND PLANTING

17. MANAGEMENT OF CLUMPS

18. Bamboo clumps should be well taken cared in order to have a good bamboo stand; Branches at the base of the culm up to eye level should be removed; Matured small bamboo culms must be also removed in order to reduce competition on the uptake of nutrients, water, sunlight and space; Besides, a properly managed bamboo clump reduced the harborage of rats and insects; It also provides a better chance for growth of more and bigger shoots; If the shoots are harvested for food purposes, they should be covered with dried weeds so that they will remain soft until they are about a meter tall.
