What are the details of the rooting medium?
Properties of rooting medium needed: The medium must support plant pieces so that they remaining particular positions. It should minimize water loss from buried parts and provide a moist but well-aerated bed for root initiation and development. Bed Preparation: Usually a three-layered structure is prepared (Figs. 2,4).The bottom layer should be gravel and large size sand; the middle, medium sized sand; and the top, fine sand. Each layer should be 7–10 cm deep. Beds are normally ca.1.2 m x 12 m in size but length can vary. They are held in place by making a boundary of bricks. Sand used in preparing the bed should be clean. If the area is well-draining, the layered structure can be replaced by one type of sand: medium to fine. Beds should be on level ground to maintain uniform moisture throughout. Advantages of Sand: Sand is inexpensive, often readily available locally, can be washed and reused, provides good drainage, enables rooted plant parts to be dug up easily and maintains a reaso
