Water thoroughly during the active growing season, typically spring and summer, allowing the soil to dry out slightly between waterings.

Reduce watering significantly during the dormant period in autumn and winter, keeping the soil barely moist to prevent bulb rot. Overwatering is a common cause of failure.

Pruning is minimal for Drimia altissima. Remove any dead or yellowing leaves as they appear to maintain a tidy appearance and prevent potential disease.

Cut back the flower stalk after blooming if desired, but this is not strictly necessary for the plant's health.

Propagate primarily by offsets, which are small bulbs that form around the base of the parent plant. Carefully separate these offsets during repotting in spring and pot them individually.

Seed propagation is possible but slower and less common for home growers.

Repot Drimia altissima every 2-3 years, or when the pot becomes crowded with offsets. This is best done in spring before new growth begins.

Use a well-draining potting mix, such as a cactus or succulent blend, and a pot with drainage holes.
