In order to grow bamboo, the player has to equip a shovel and plant the stalks in a manner analogous to planting trees. The bamboo sprout will develop into a bamboo stalk once it has been in the environment for three days. When bamboo has reached its maximum size, it begins to develop shoots in the form of fissures that may be dug up with a shovel.
In Animal Crossing: New Horizons, in order to obtain bamboo and plant it, you must first obtain a Bamboo Shoot. Alternatively, you may obtain a fruit boost and dig up an entire bamboo plant. The only way to accomplish that, which is unfortunately the only option, is to go on a Mystery Islands Tour and cross your fingers that the island you go to has bamboo on it.
