Plant your tea tree where it can get a fair amount of sunlight but where it also can enjoy shade. Temperatures for a thriving tea tree are between 60 degrees and 68 degrees Fahrenheit. A tea tree should not be exposed to temperatures below 45 degrees Fahrenheit during the winter.
Water your tree about once every seven days--just so that the soil is moist--and fertilize it every two weeks from January until June. Any basic liquid fertilizer works well. If you have a natural manure fertilizer on hand, that also will work well.
Move your tea tree outside if it has been inside beginning in June. Reduce the water and bring it inside once the temperatures begin to fall. Your tea tree should be in a light-filled yet cool place in your house when you bring it inside.
Water your tea tree regularly during November and December as the flowers begin to bloom. This usually amounts to about once or twice every seven days. Keep in mind that your tea tree likely will get natural watering from rain, which is why you do not need to water it on your own more than once a week. You will want to keep the soil moist (even though tee trees can adapt to both moist and dry soils) but not overwatered to avoid root rot.
