Most important thing is not to overwater it. Dont let it stand in water. Just water it when the compost feels dry or the pot feels light. If it needs water you will notice that the leaves and flowers begin to droop. But if you overwater it the symptoms are the same, but you wont get it to revive.

i keep mine in bright but indirect sun light. water as cinders says. I give mine a baby bio feed monthly during the active growing period and nothing in the less growth period.

If you have hard water, or mechanically softened water, it will also appreciate rainwater or purified water instead, as it is somewhat sensitive to excess minerals.
