Care Instructions
Helianthemum nummularium is relatively easy to care for. It prefers full sun and should be watered sparingly, allowing the soil to dry out between waterings. The plant thrives in moderate temperatures and average humidity levels. It is well-suited for rock gardens and other sunny, well-drained locations.Soil
This plant prefers well-drained, loamy soil. It can tolerate poor soil conditions but performs best in moderately fertile soil. Good drainage is essential to prevent root rot, so a soil mix with sand or gravel can be beneficial.Fertilizer
Helianthemum nummularium does not require heavy fertilization. A balanced fertilizer with a composition of 5-10-10 can be applied in the spring to promote healthy growth and flowering. Fertilize sparingly to avoid overfeeding.Repotting
Repotting is generally not necessary for this plant, as it is typically grown outdoors in garden settings. However, if grown in containers, repotting can be done in the spring when the plant outgrows its pot. Use a well-draining soil mix and ensure the new pot has adequate drainage holes.Propagation
Propagation can be done through seeds or cuttings. Seeds can be sown in the spring, while cuttings can be taken in the summer. For cuttings, select healthy, non-flowering shoots and root them in a well-draining soil mix.Pruning
Pruning is beneficial to maintain the plant's shape and encourage bushier growth. Prune after flowering by cutting back the stems to promote new growth. Remove any dead or damaged stems to keep the plant healthy.Toxicity
Helianthemum nummularium 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
Helianthemum nummularium is a great choice for rock gardens, borders, and ground cover. It is drought-tolerant once established and can attract pollinators such as bees and butterflies to the garden.REVOLUTIONIZE YOUR PLANT CARE
