How to plant Helianthus?
Helianthus are easy plants to grow in the ground in a natural garden. We recommend planting them in spring, once all risk of frost has passed. Choose a sunny spot with well-drained soil. Helianthus prefer nutrient-rich soil, but avoid using chemical fertilisers to encourage natural growth.
Before planting helianthus, loosen the soil by working it with a spade or fork. Dig holes about 30 cm apart and plant the young plants at the depth at which they were potted. Water generously after planting to help the roots establish.
If you want to transplant existing helianthus, do so in spring by dividing the clumps with a spade. Be sure to replant the divisions quickly and water them well afterwards.
If you want to transplant helianthus that are already in place, do so in spring by dividing the clumps using a spade.
By following these simple tips, you'll be able to enjoy beautiful helianthus in your garden, without the use of chemical fertilisers.
