Maintain consistently moist soil for Woodland Bittercress, avoiding waterlogged conditions. Water thoroughly when the top centimeter of soil feels dry to the touch.

Reduce watering slightly during periods of slower growth or dormancy, but never allow the soil to dry out completely.

Pruning is typically not necessary for Cardamine flexuosa. Remove any dead or unsightly foliage as needed to maintain a tidy appearance.

If the plant becomes too leggy or spreads aggressively in an undesirable location, it can be trimmed back to encourage bushier growth or to manage its size.

Woodland Bittercress readily self-seeds and can also be propagated by division. In spring or fall, carefully divide established clumps, ensuring each section has roots and shoots.

Seeds can be sown directly into moist soil in fall or early spring, often germinating with cool stratification.

Repotting is rarely required for this groundcover species, as it prefers to naturalize. If grown in a container and it becomes root-bound, repot in spring into a slightly larger pot with fresh, well-draining potting mix.

Ensure good drainage to prevent root rot.
