WaterRock cress requires moderate watering, especially during dry spells. It is important to allow the soil to dry out slightly between waterings to prevent root rot. Generally, water rock cress with about one inch of water every week, but adjust this amount during periods of heavy rainfall or drought. Overwatering can lead to fungal diseases, so it's best to lean towards underwatering rather than overwatering. During the growing season, ensure the plant receives a consistent amount of water for optimal growth and flowering.
LightRock cress thrives in full sun but can tolerate partial shade. For best flowering results, plant it in a location where it will receive at least six hours of direct sunlight daily. Adequate light ensures vibrant foliage and abundant blossoms. Rock cress can suffer in too much shade, where it may become leggy and produce fewer flowers.
TemperatureRock cress is hardy and can withstand a wide range of temperatures, generally surviving winters as cold as -20°F and thriving in summer temperatures up to 85°F. The ideal temperature for rock cress during its active growth is between 60°F and 75°F. Sudden extreme temperature changes can impact the plant's health, so it's best to plant it in a location with some shelter from harsh weather.
PruningPrune rock cress to maintain its shape and encourage thicker growth. After the plant has finished flowering, usually in late spring or early summer, trim back about a third of its growth to prevent it from becoming leggy. Regular pruning promotes a second bloom and keeps the plant compact and healthy. Pruning is also the time to remove any dead or damaged foliage.
CleaningAs needed
SoilRock Cress requires well-draining soil with gravelly or sandy characteristics, mixed with compost for fertility. Preferred soil pH is slightly alkaline, ranging from 6.5 to 7.5.

Life cycleAubrieta gracilis 'Kitte', commonly known as Rock Cress, begins its life cycle with seed germination, typically occurring in spring when temperatures are favorable. Upon germination, the seedlings establish themselves and develop a rosette of hairy leaves close to the ground. As the plant matures, it enters the vegetative growth stage, during which it spreads out to form a low, mat-like ground cover. Following vegetative growth, Rock Cress enters the flowering stage in late spring to early summer, producing small, purple to violet flowers that attract a variety of pollinators. After pollination, seeds are produced and dispersed, allowing the cycle to begin anew. During winter, Rock Cress experiences a period of dormancy, with the foliage often persisting but growth significantly slowing down until the return of warmer weather.
PropogationPropogation time
Spring-Early Summer
For the plant Aubrieta gracilis 'Kitte', commonly known as rock cress, the most popular method of propagation is by seed. Sowing seeds can be carried out in the spring or autumn. In spring, scatter the seeds over a well-draining soil mix, barely covering them with a fine layer of soil, and maintaining a consistent moisture level without waterlogging. Germination typically occurs within two to three weeks at temperatures of 65-75°F (18-24°C). Once seedlings have developed several sets of true leaves, they can be carefully transplanted to individual pots or their final location in the garden, ensuring they have full sun to partial shade and good drainage to thrive.
