Water regularly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as Fumaria parviflora prefers slightly moist conditions and can be susceptible to root rot if waterlogged.

Ensure good drainage in pots.

Prune lightly after flowering to maintain a tidy appearance and encourage reblooming. Remove any dead or leggy stems. Pinching back young plants can promote bushier growth.

Propagate by sowing seeds in spring or autumn. Seeds can be sown directly into the ground or in pots. Germination may take several weeks. Division of established clumps is also possible in spring.

Repot young plants annually in spring before new growth begins. Mature plants can be repotted every 2-3 years or when they become root-bound. Use a well-draining potting mix.
