Light
Bright filtered light works well. If winter daylight is weak, supplemental light can support growth, but do not interrupt the long dark period used to initiate buds.
Watering
Water thoroughly when the mix begins drying and let excess drain. Do not leave the roots sitting in water.
Soil
Use a light mix with good drainage and root-zone aeration rather than dense heavy soil.
