Light: Bright light, especially during the summer growing season. Full sun is preferable in the summer, with as much light as you can give during the winter.
Water: Keep the plants moist at all times during the growing season, and you might have to water larger plants twice a day in heat. During winter, reduce watering but don’t let them dry out.
Temperature: Warm in summer (household temperatures are fine) and colder in winter months (down to 50˚F at night). They are generally hardy, and even if they die back to the soil, they will likely recover next spring.
Soil: A rich, fast-draining mix is ideal.
Fertilizer: Fertilize adequately during the growing season, with controlled-release fertilizer and liquid fertilizer.
