watering

Soft-Haired Rockcress should be watered regularly to keep the soil slightly moist but never soggy. Water your plant as soon as the top inch of soil feels dry to the touch. When watering Soft-Haired Rockcress, water at the base of the plant, avoiding the foliage. Avoid wetting the foliage as much as possible to prevent fungal diseases. During the active growing season (spring and summer) the plant should be watered once a week, or more frequently in hotter and drier conditions. During the dormant season (autumn and winter), water less often, approximately 1-2 times per month.

sunlight

The Soft-Haired Rockcress (Arabis adpressilis) plant species thrives best in direct sunlight for at least 6-8 hours a day. When the plant is grown outdoors in full sun, it will produce the best blooms. The sun should be strongest and brightest in the early morning and late afternoon, especially during the warmer summer months. This plant species does not do well in shaded areas and should not be grown in areas that do not receive ample amounts of direct sunlight. If the plant is not getting enough sunlight it can become weak and will struggle to produce flowers. In order to ensure that the Soft-Haired Rockcress grows healthy and productive, it is important to provide it enough direct sunlight.

pruning

Soft-Haired Rockcress is an evergreen perennial that prefers to be pruned in the spring. Prune back the stems lightly to shape and remove any dead or diseased growth. To keep the plant bushy and full, it is best to cut back the stems to the base, removing up to 1-third of the stems at a time. Light pruning may be done annually in the late winter or early spring to keep the plant looking healthy. This will help to prevent overgrowth and keep the plant in a neat and tidy shape.
