Learning Download: How to Grow Helenium
Helenium is also commonly known as Sneezeweed and blooms bright yellow flowers that resemble daisies. It is a perennial, but it will live for about four to five years.
Before Planting: Sow Helenium seeds indoors 8 to 10 weeks before the last frost. Transplant the flowers outside when the air is cool and there is still possibility of a frost.
Planting: Direct sowing can take place in the early spring or the early fall. When planting, barely cover the seeds with soil.
Watering: Keep the soil moist between watering.
Fertilizer: Feed Helenium once each spring with a balanced, slow-release fertilizer. Make sure you apply the fertilizer just before the new growth begins.
Days to Maturity: Helenium will bloom from the late summer to early fall.
Harvesting: Helenium can add to a bouquet’s appearance due to its clustered bloom and tall stems.
Tips: In the late June, cut the Helenium plants back to half of its height. This will make the foliage thicker and encourage more flowering the following spring.
