Care Instructions
Maximilian sunflower thrives in full sun and requires moderate temperatures. It prefers soil that dries out almost completely between waterings. The plant can tolerate a range of humidity levels but does best in moderate humidity. Regular pruning helps maintain its shape and encourages more blooms.Soil
This plant prefers well-draining loamy soil. It can tolerate poor soil conditions but performs best in moderately fertile soil. Ensure the soil has good drainage to prevent waterlogging.Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant once in the early spring and again in mid-summer to support its growth and flowering.Repotting
Repotting is generally not necessary for outdoor plants. However, if grown in containers, repot every 2-3 years to refresh the soil and provide more space for root growth. Repot in early spring before new growth begins.Propagation
Maximilian sunflower can be propagated by seeds or division. Sow seeds in early spring or divide the root clumps in late fall or early spring. Ensure the new divisions have adequate roots and replant them immediately.Pruning
Prune the plant in late winter or early spring before new growth starts. Remove any dead or damaged stems and cut back the previous year's growth to encourage new shoots. Regular deadheading during the blooming season can also promote more flowers.Toxicity
Helianthus maximiliani is not toxic to pets or humans. All parts of the plant are considered safe.Additional
Maximilian sunflower is a great addition to wildflower gardens and naturalized areas. It attracts pollinators such as bees and butterflies, making it beneficial for the ecosystem. The plant can also be used for erosion control due to its extensive root system.REVOLUTIONIZE YOUR PLANT CARE
