How to keep Aubrieta Canescens.
Light
Purple rock cress prefers intense sunlight but can tolerate somewhat shadier conditions that improve its growth and fertility. Its natural habitat features abundant sun. Excessive shading may lead to weaker foliage and reduced flowering, while too much sun can cause leaf burn.
Temperature
Purple rock cress originates from temperate regions and prefers temperatures between 68 and 95 °F (20 to 35 ℃). In every season, proper temperature regulation is important to recreate its native habitats. Extended exposure to extreme cold or heat should be avoided to preserve its health.
Fertilizer
The best time to fertilize a Purple rock cress is in early spring, as it emerges from dormancy and starts active growth. Fertilization supplies essential nutrients needed for healthy development. Although Purple rock cress has fairly low fertilizer requirements, applying fertilizer annually can improve its survival and encourage better, longer-lasting blooms.
Pot & Repot
When repotting Purple rock cress, choose a pot 1-2 inches (2.5–5.1 cm) larger with ample drainage. Use a well-draining potting mix. Repot in spring or fall, ensuring that the root ball is slightly lower than the rim of the flower pot. Water thoroughly after repotting and place in a warm spot with indirect sunlight.
