watering

Colewort should be watered regularly to ensure its roots stay adequately moist. Depending on your climate and the potting soil you're using, the Colewort may need to be watered once or twice a week. During times of warmer weather or intense sunlight, the Colewort may need more frequent watering. Use your finger to check the top 2 inches of the soil to determine if it is dry. If the soil is dry, it needs to be watered. Avoid overwatering and instead allow the soil to dry out between waterings.

sunlight

Colewort (Crambe cordifolia) requires full sun to grow and develop properly. It is particularly sensitive to extended periods of shade and will suffer from stunted growth if it does not receive enough sunlight. While the exact amounts of sunlight needed may vary depending on the specific climate, it should receive at least 5-6 hours of direct sunlight per day in order to thrive. Direct sunlight during the early hours of the day is most beneficial to this species as it typically will help it to develop properly. In addition, Colewort may also benefit from receiving some indirect light during the later hours of the day.

pruning

Colewort should be pruned in late winter or early spring. Pruning should be done selectively, removing any dead, diseased, or damaged stems and branches. This will improve the overall form and health of the plant. Young plants can be pruned harder than mature plants; this helps to promote dense, bushy growth. Mature plants should be lightly pruned to control their size and maintain symmetry. At least 1-third of the stems should be removed with each pruning. The remaining stems should be pruned to their desired shape and size. Colewort should never be pruned too severely as this could kill it.
