Soft-Haired Rockcress

Kamchatka Rockcress should be watered when the surface of the soil is dry to the touch, usually about twice a week. Water deeply rather than often, ensuring that the soil is evenly moist throughout the root zone. During active growth, you may need to water as often as 3 times a week. Allow the top inch of soil to dry out to the touch before watering again. Too little water can cause the soil to become compacted and impede drainage, so keep an eye on water levels.

Kamchatka Rockcress (Arabidopsis lyrata subsp. kamchatica) is best grown in full sun. The plants need a minimum of 6 hours of sunlight each day for optimal growth and flowering. During the spring and summer months, this plant species will thrive with 10 hours of direct sunlight daily. In cooler climates, it is best to provide the plants with a maximum 8 hours of direct sunlight per day. When planting this species, make sure to provide rich, moist, and well-draining soil to ensure maximum growth and health. When grown indoors, make sure to place the plants in a sunny location to achieve optimal growth.

Kamchatka Rockcress should be pruned lightly and often for best results. Pruning should take place in early spring and throughout the growing season in order to keep the plant bushy and promote vigorous flowering. Early spring pruning should focus on removing any dead and damaged material. During the growing season, prune to control the spread of the plant, remove long or congested stems, and reduce the number of flowers for larger plants. A yearly pruning helps to maintain an attractive shape and encourages the production of new flowers. It is best to prune in the winter or early spring just before new growth appears. Pruning off small amounts of the stem at the top and side of the plant will prevent the plant from becoming overgrown and will encourage bushiness and re-bloom.
