The leaves may be misted between soakings. Misting and any watering should be done in the morning. It is important to water the plant first then fertilize after. Pot size should be as small as possible. The distant from the center of the plant to the side of the pot should be less than two inches in average.
Plastic pots are good for keeping the moisture in the pot.
A regular clay pot is good for air circulation. A tall clay pot is good only if the plant has long roots. A shallow pot is good only if the plant has crawling roots or short roots. Be very careful if you choose to use a highly glazed clay pot, because sometimes air does not go through the glazed wall of the pot. Even though with several holes at the wall of the pot, these highly glazed clay pots do not allow much air circulation.
