Rockcress is fairly disease-resistant and is generally unlikely to suffer from illnesses. However, it can still be vulnerable to pests and diseases found in its surroundings. Such infections are usually mild. Carewise, this plant requires a moderate level of maintenance. It should be pruned regularly to preserve an attractive appearance and healthy growth. Fertilizing can also encourage flowering. Rockcress is appropriate for anyone with outdoor space, such as a garden or patio, and does not demand extensive care experience. It may need more attention if cultivated indoors.
How to keep Arabis Nova.
Light
Rockcress comes from bright, open habitats where it does best in full sun. It can tolerate some partial sun but prefers direct sunlight for its best growth. This annual and biennial plant is noted for its sun-loving nature.
Water
Native to rocky alpine regions, rockcress prefers well-drained soil and is drought-tolerant. For optimal growth, it is recommended to water it twice a week. When grown indoors, rockcress thrives with consistent light and careful watering to prevent root rot. It also favors cooler temperatures and increased moisture during the spring.
Fertilizer
Resume fertilizing once most of Rockcress’s blooms have opened fully. Around the period when blooms are at their peak, apply fertilizer every three to four weeks, weather permitting. Then, when Rockcress begins to produce fewer new blooms, stop fertilizing; there is no need to feed the plant when it can no longer produce additional flowers.
Pruning
Rockcress is a hardy perennial known for its vibrant blooms and ability to serve as ground cover. To encourage bushy growth, prune the plant after it finishes flowering in late spring. Remove any spent flowers and leggy stems, but avoid cutting into old wood. Regular pruning not only enhances air circulation but also reduces the risk of disease and promotes vigorous growth.
