Prepare the suitable ground for bamboo growing.

Bamboo is a fast-growing perennial evergreen tree. The root system is very concentrated and dense. So Warm humid climate is necessary for bamboo growing. The annual average temperature should be 15-25°C.The annual precipitation should be 1200-1800mm.

What’s more, Bamboo needs a great deal of sun, so you should usually pick a yard that receives 8 or more hours of sun daily. Shade can be especially important during winter. The combination of frost and direct sunlight can dehydrate the plant quickly. As such, if you live in an area that receives frost during winter, you should opt for a spot that receives partial shade instead of one with direct sun.

The suitable ground is the valley terrace at an altitude of 800 meters, slope piedmont gentle slope under 25°. Select the Leeward Sunning dale, good drainage and irrigation, soil layers deep seedbed.
