DETAILS

Care Instructions
Heliopsis helianthoides is relatively easy to care for. It prefers full sun and moderate temperatures. Water the plant when the soil partially dries out, and ensure it has good air circulation. It can tolerate a range of humidity levels but prefers moderate humidity.
Soil
This plant prefers well-draining loamy soil. It can tolerate a range of soil types but thrives best in soil that is rich in organic matter. Ensure the soil is not waterlogged to prevent root rot.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant once a month during the growing season to promote healthy growth and flowering.
Repotting
Repot Heliopsis helianthoides every 2-3 years or when it outgrows its current pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repot in the early spring before the growing season begins.
Propagation
Propagate Heliopsis helianthoides through division or seeds. Division can be done in the spring or fall by separating the root clumps. Seeds can be sown in the spring after the last frost.
Pruning
Prune the plant in late winter or early spring to remove dead or damaged stems. This encourages new growth and helps maintain the plant's shape. Deadheading spent flowers can also promote continuous blooming.
Toxicity
Heliopsis helianthoides is not toxic to pets or humans. It is safe to grow in gardens where children and pets are present.
Additional
Heliopsis helianthoides is a great addition to pollinator gardens as it attracts bees, butterflies, and other beneficial insects. It is also deer-resistant, making it a good choice for gardens in areas with high deer populations.
