Choosing the Right Pot
You need not worry if you don’t have an extensive garden. Star Anise does pretty well in pots. Start the seeds in a 12-14-inches pot. Transplant it to a bigger pot once you find the roots spreading out of the drainage hole.
If you have bought a plant from a nursery, then move it to a one size bigger pot than the current one. Do it once the plant has acclimatize your environment.
