Care Instructions
Helianthus mollis thrives in full sun and requires moderate temperatures. It prefers soil that dries out almost completely between waterings. Ensure the plant receives plenty of direct sunlight and maintain moderate humidity levels. Regular pruning helps maintain its shape and encourages healthy growth.Soil
This plant prefers well-draining loamy soil. It can tolerate a range of soil types but performs best in nutrient-rich, slightly acidic to neutral soil. Good drainage is essential to prevent root rot.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season to promote healthy growth and vibrant blooms. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.Repotting
Repot Helianthus mollis when it outgrows its current container or every 2-3 years. Choose a slightly larger pot with good drainage. Gently remove the plant from its old pot, loosen the roots, and place it in the new pot with fresh soil.Propagation
Propagate Helianthus mollis through seeds or division. Sow seeds in early spring or divide the plant in late spring to early summer. Ensure the new divisions have a healthy root system and plant them in well-prepared soil.Pruning
Prune Helianthus mollis in late winter or early spring before new growth begins. Remove any dead or damaged stems and cut back the plant to encourage bushier growth. Regular deadheading of spent flowers can also promote continuous blooming.Toxicity
Helianthus mollis is not known to be toxic to pets or humans. However, it is always advisable to keep plants out of reach of pets and children to prevent any accidental ingestion.Additional
Helianthus mollis is a great addition to pollinator gardens, attracting bees and butterflies. It is also relatively drought-tolerant once established, making it a low-maintenance choice for sunny landscapes.REVOLUTIONIZE YOUR PLANT CARE
