Care Instructions
Rock Candytuft thrives in full sun and prefers moderate temperatures. It is relatively drought-tolerant and should be watered sparingly, allowing the soil to dry out between waterings. The plant does well in average humidity and can tolerate a range of temperatures, making it easy to care for.Soil
Iberis saxatilis prefers well-draining soil, ideally a loamy mix. It can tolerate poor soil conditions but thrives best in moderately fertile soil. Good drainage is essential to prevent root rot.Fertilizer
Fertilize Rock Candytuft with a balanced fertilizer, such as 5-10-10, in early spring before new growth begins. This will help promote healthy blooms and foliage. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.Repotting
Repotting is generally not necessary for Rock Candytuft, as it is typically grown outdoors in garden beds or rock gardens. However, if grown in containers, repot every 2-3 years to refresh the soil and provide more space for root growth.Propagation
Iberis saxatilis can be propagated by seed, cuttings, or division. The best time to propagate is in late spring or early summer. For cuttings, take a 3-4 inch stem cutting, remove the lower leaves, and plant in a well-draining soil mix. Keep the soil moist until roots develop.Pruning
Pruning is beneficial for maintaining the plant's shape and encouraging new growth. Prune back the stems after flowering to prevent the plant from becoming leggy. Remove any dead or damaged stems to keep the plant healthy.Toxicity
Iberis saxatilis is not known to be toxic to pets or humans. It is generally considered safe to grow in gardens where pets and children are present.Additional
Rock Candytuft is a low-maintenance plant that is perfect for rock gardens, borders, and ground cover. It attracts pollinators such as bees and butterflies, making it a great addition to any garden focused on supporting local wildlife.REVOLUTIONIZE YOUR PLANT CARE
