Generally, the planting site should have well-distributed rainfall and it is better to avoid plantation waterlogged areas. Irrigation is essential for both bamboo nurseries and well as for plantations. Artificial irrigation improves the establishment and growth of bamboo and in case proper drainage is not available in the area, it has to be provided artificially. In dry spells, irrigation at 8-13 times with 10-12 litres per plant for the initial 2 years can be provided.
A drip irrigation system will be the best solution to optimize water use. Similarly, the use of a clay pot buried up to the neck in the root zone of the bamboo can be considered if the situation permits regular refilling of the water as it gets used up. The use of an inverted plastic bottle with a wick inserted in the neck to permit slow outflow of water is another simple option. Heap/mound the soil mixture around and over the base of the plant and prepare a trench (at least 50 cm radius) around the bamboo plant will help to retain water.
The quantity of water required and mode of irrigation are species-specific, for example, Dendrocalamus strictus is suitable for rainfed areas whereas D. hamiltonii and D. stocksii, Pseudoxytenanthera ritcheyi are the ideal species that require minimal irrigation is required.
