Greenland Rockcress

Greenland Rockcress likes moist but well drained soil, so it should be watered deeply but moderately. Water it about once a week, and always let the soil dry out completely between waterings. In periods of drought or hot weather, it can be watered twice a week. Make sure not to overwater the plant, as this can lead to root rot.

Greenland Rockcress (Braya thorild-wulffii) require full to partial sunlight to thrive and bloom. The plant does best in locations that have 6 to 8 hours of direct sunlight every day. This amount of sunlight allows the plant to photosynthesize energy from the sun, ensure efficient growth and development, and promote flowering. If the plant does not have access to sufficient sunlight, it can suffer physiological damage and can become chlorotic. For Greenland Rockcress, the ideal time of day for sunlight exposure is 10am to 4pm.

Greenland Rockcress (Braya thorild-wulffii) can be pruned in late winter or early spring to shape and control their size. Pruning should be done before the new growth emerges, as new growth can be damaged by heavy pruning. To maintain an optimal size, remove any dead or spindly stems, and selectively prune individual shoots as needed. Prune lightly to avoid removing more than a third of the plant’s structure, and take care to avoid cutting off flower buds. For plants that are less durable, pruning can be done in late summer or early autumn to reduce the risk of frost damage. Avoid making drastic changes to the shape or form of a Greenland Rockcress plant, as it is not able to handle the stress of major pruning.
