It requires moderate to high humidity, and temperature ranges between 18-25 °C. The plant can be propagated through seeds or by dividing the rhizomes during early spring or late fall.
Watering needs
The watering needs for Sopubia filiformis are moderate. It needs consistent moisture in the soil, but it should not be waterlogged. Under watering can cause the leaves to wilt, and overwatering can lead to root rot. It is best to water the plant when the top inch of soil feels dry to the touch.

Water the cutting regularly and keep it in a shaded area. It takes about 4-6 weeks for the cutting to develop roots.
Propagation of Sopubia filiformis through stem cuttings is more reliable and quicker than propagation through seeds.
