Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as Sonchus bulbosus prefers slightly drier conditions once established. Reduce watering during its dormant period in summer.

Prune back spent flower stalks to encourage further blooming or to maintain a tidy appearance. Remove any yellowing or dead foliage as needed. Heavy pruning is generally not required.

Easily propagated by division of its tubers during dormancy or early spring. Seeds can also be sown in autumn or early spring. Ensure good drainage for seed starting.

Repot every 2-3 years in spring, just as new growth begins. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current root ball.
