Bamboo is usually very hardy, and can be grown in plain water. To move it into a dirt setting, make sure it is getting the same amount of light it was getting in water, and the dirt should be very moist, but not flooded.
1) Consider a planting pot quite big enough as bamboo grows fast and its roots need space. 2) Plant bamboo in the pot and fill it with dirt and soil. 3) Make sure soil remains moisten for good growth of bamboo, for this keep watering the soil every two days.
