Water
Water consistently during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in fall and winter when the plant is dormant.
Avoid waterlogging, which can lead to root rot.

Watering, pruning, propagation, and repotting details from plant data
Water consistently during the growing season, allowing the soil to dry slightly between waterings. Reduce watering significantly in fall and winter when the plant is dormant.
Avoid waterlogging, which can lead to root rot.
Remove spent flower stalks once blooming is finished to encourage further flowering and maintain a tidy appearance. Cut back yellowing foliage in late fall or early winter before dormancy.
Dispose of diseased or damaged parts promptly.
Tuberose is primarily propagated from offsets (daughter bulbs) that grow from the main bulb. Separate these offsets during repotting in spring. Allow them to dry for a day or two before replanting in well-draining soil.
Repot tuberose every 2-3 years in spring before new growth begins. Choose a pot that is only slightly larger than the bulb and ensure it has good drainage. Use a well-draining potting mix, such as a sandy loam.
