Water consistently, allowing the soil to dry slightly between waterings. Fumaria agraria prefers well-drained soil and is susceptible to root rot if overwatered.

Reduce watering in cooler months when growth slows, but do not let the soil become completely arid.

Prune after flowering to maintain shape and encourage bushier growth. Remove spent flower stalks and any dead or leggy stems.

Light trimming can also be done to encourage a more compact form, especially if grown in containers.

Propagate by seeds sown in autumn or early spring. Seeds may benefit from a period of cold stratification.

It can also be propagated by division of clumps in spring, though this is less common and may be more challenging.

Repot young plants annually in spring, and established plants every 2-3 years. Use a well-draining potting mix.

Choose a pot only slightly larger than the previous one to avoid overwatering and encourage root development.
