White Cuckoo Bitter-CressCardamine dentata

Maintain consistently moist soil. Water thoroughly when the top centimeter of soil begins to dry out. Avoid waterlogged conditions, which can lead to root rot. In warmer weather, more frequent watering may be necessary.

Ensure good drainage to prevent standing water.

Prune after flowering to maintain a tidy appearance and prevent excessive self-seeding. Remove any dead, damaged, or leggy stems. Trimming can also encourage denser growth.

Regular deadheading of spent flowers can prolong the blooming period.

Easily propagated from seed sown in autumn or early spring, either directly outdoors or in a cold frame. Division of established clumps in spring or autumn is also effective.

Softwood cuttings can be taken in late spring or early summer.

Young plants may benefit from repotting annually or biannually in spring to provide fresh soil and more space. Mature plants are generally content in their pots and may not require frequent repotting, usually only when root-bound or the soil has degraded.
