Helenium Planting and Care Guide
Quick Facts About Helenium
Helenium is a perennial native to North America that produces pleasant blooms that are great for cutting. It is effective at attracting pollinators, and can survive for many years.
Planting Time
Helenium seeds should be started indoors 8-10 weeks before the end of frost season, or directly outdoors after all frost danger has passed.
Planting Location
Plant Helenium in an area of full sun in average soil that drains well.
How to Grow Helenium
- To start indoors, use trays or small pots filled with a seed starter mix. Surface sow 3-4 seeds per plant, and lightly press into soil without covering.
- If sowing directly outdoors, first prepare a seedbed by breaking up soil and removing weeds.
- Keep seeds moist until germination, maintaining a temperature of 65-70F degrees. Under proper conditions, these seeds should germinate in 2-3 weeks.
- Once indoor seedlings have their first few sets of true leaves, they can be transplanted outdoors after all frost danger has passed.
- Before transplanting seedlings into the garden, it's essential to "harden them off". This involves acclimating young plants to outdoor conditions by placing them in a sheltered outdoor area for about a week. Initially, shield them from strong winds and direct sunlight. If there's a risk of frost overnight, either cover the plants or bring them indoors, then return them outside in the morning. This hardening off method helps strengthen the plant's cell structure, minimizing transplant shock and sun damage.
Care And Maintenance
- Keep weeds under control during the growing season. Weeds compete with plants for water, space and nutrients, so control them by either cultivating often or use a mulch to prevent their seeds from germinating.
- Mulches play a vital role in preserving soil moisture and ensuring consistent soil temperatures. When it comes to annuals, using organic mulch made from shredded leaves not only enhances the appearance of the bed but also enriches the soil as it decomposes over time. Remember to keep mulch away from the plant stems to avoid potential rot issues.
- Helenium should be watered consistently, not allowing the soil to dry out between waterings.
- Perform a balanced application of slow-release fertilizer at the beginning of the growing season.
- Pinch plants in the spring to encourage sturdier growth, and regularly deadhead spent blooms during the growing season to encourage further flowering.
