rock cress

Rock cress is a relatively drought tolerant plant that does best when watered thoroughly once or twice a week. To ensure that the soil remains moist but not oversaturated, it is best to water only when the top 2–3 inches (5–7 cm) of soil feels dry to the touch. If the weather is especially hot, then it may need to be watered more frequently. Make sure to water deeply, as this will encourage the roots to grow further down into the soil and will help the plant to establish itself.

Rock cress should be planted in full sun, which means 6-8 hours of direct sunlight per day. It prefers cool weather and can tolerate temperatures as low as -30°F. To ensure optimal growth, prune the plant as needed so that it does not become overly bushy. The soil should be moist and well-draining, and some shade should be provided during the hottest hours of the day when temperatures become exceptionally high. With its semi-evergreen foliage, it is best to water rock cress every few days, allowing the soil to dry out slightly between waterings.

Rock cress should be pruned once a year in late winter or early spring. Depending on the size and location of the plant, you may need to prune and shape more often. It is best to remove up to 1-third of the previous season's growth. Prune rock cress back to encourage bushy growth and keep plants from becoming leggy. Be sure to remove any flowering shoots, as this will encourage more blooms in the next growing season. Regular pruning also helps to keep plants healthy by removing any diseased or dead material.
