Most of them come from tropical areas and prefer a sunny and warm room temperature (24 degrees Celcius).
Keep them away from heaters in winter because the air is too dry.
Watering should be done once a week, if the soil is dry or the pot is light weight when you lift it.
Make sure there is no water sitting at the bottom of the pot , to avoid infestations of insects, diseases and other pests that thrive in those conditions.
Fertilize with a 20-20-20 type to help them to produce and keep nice leaves. Follow manufacturer instructions. In winter, stop the fertilization because most of them are dormant and start again in March.
