Place your bamboo into a large pot that permits at least two inches of distance between the edge of the roots and the edge of the pot. Fill your pot with nutrient-rich soil, thereby securing your bamboo plant. It is likely that your bamboo will come already planted in a suitable pot. However, as your bamboo grows, you may find it necessary to transfer your plant to a larger pot; use these same guidelines if repotting your bamboo.
Position your bamboo in a location that is exposed to natural sunlight. Water your bamboo with a mixture of plant food; mixing in a nitrogen-rich plant food with an N-P-K of 21-5-6 with every watering will help your bamboo thrive. Water your bamboo so that the soil is moist but not saturated. Bamboo is a type of grass and may die if overwatered.
Continue to water as needed. Let the soil be your guide -- it should be moist but never overly wet. In the winter, the amount of water necessary will decrease and your bamboo will lose its leaves. This is a natural development; the leaves will regrow when the amount of daylight increases.
Prune your tree as necessary -- usually no more than one major pruning a year and minor adjustments as needed. Being that your bamboo is indoors, you will want to keep it from outgrowing its living space.
