Bitter WintercressBarbarea vulgaris

Bitter wintercress prefers consistently moist soil but can tolerate some dryness once established. Water regularly, especially during dry spells, to maintain soil moisture.

Avoid waterlogging, as this can lead to root rot. Deep watering is more beneficial than frequent shallow watering.

Pruning is mainly done to remove spent flower stalks, diseased or damaged foliage, and to control the plant's size and shape. Regular deadheading can encourage a longer blooming period.

Cut back stems to just above a leaf node or the ground.

Bitter wintercress can be easily propagated by seeds sown directly outdoors in early spring or late autumn. It also readily self-seeds.

Division of established clumps in early spring or autumn is another effective method for propagation.

Repotting is rarely necessary for bitter wintercress, as it is often grown as a perennial or annual from seed and can naturalize. If grown in containers, repot when the plant becomes root-bound, typically every 2-3 years, in spring or autumn.
