Planting Helenium ‘Moerheim Beauty’

Proper planting is key to getting Helenium ‘Moerheim Beauty’ established in your garden. Follow these tips when siting and planting your Helenium:

Site Selection

  • Select a site with full sun exposure. Helenium ‘Moerheim Beauty’ thrives in a sunny spot and produces the most prolific blooms when grown in full sun. At least 6 hours of direct sunlight per day is ideal.
  • Choose a location with well-draining soil. Helenium does not tolerate wet, soggy soil and is susceptible to root rot if overwatered. Make sure your planting site has soil that drains well.

Soil Preparation

  • Prepare the soil by mixing in 2-3 inches of compost or other organic material. This will improve drainage and provide nutrients for strong root growth.
  • Test the soil pH. Helenium grows best in slightly acidic to neutral soil, with a pH between 6.0-7.0. Adjust the pH if needed.
  • Loosen the soil and remove any weeds or debris before planting. Helenium has long taproots and requires deeply worked, loose soil.

Planting Depth and Spacing

  • Dig holes 12-18 inches apart and 12-18 inches deep. Helenium has a long central taproot and needs adequate depth.
  • Place the root ball in the hole and backfill with your prepared soil mix, firming the soil gently around the base.
  • Water thoroughly after planting to settle the soil and eliminate any air pockets.
  • Allow 12-18 inches between plants to give them sufficient room to reach maturity.

Watering After Planting

  • Water thoroughly after planting and allow the soil to drain.
  • Continue watering 2-3 times per week for the first 3 months while your Helenium establishes.
  • Provide at least 1-2 inches of water per week by rainfall or supplemental irrigation.
  • Avoid overwatering, as too much moisture can lead to root rot in Helenium.

Caring for Helenium ‘Moerheim Beauty’

Once established, Helenium requires minimal care to thrive. Follow these guidelines for ongoing maintenance:

Watering Requirements

  • Provide at least 1 inch of water per week during the growing season. More water is needed during hot, dry periods.
  • Check the soil moisture before watering. Water when the top few inches become dry.
  • Avoid allowing the soil to completely dry out between waterings. Drought stress can cause leaf scorch.
  • Reduce watering in the fall as the plant enters dormancy. Resume normal watering when growth starts in spring.

Fertilization

  • Apply a balanced fertilizer once in early spring when new growth appears. Look for a 10-10-10 or similar formula.
  • Supplement with occasional liquid feedings every 3-4 weeks during the growing season for a boost. Use a dilute fish emulsion or seaweed extract.
  • Discontinue fertilizing by late summer so the plant can harden off for winter dormancy.

Deadheading

  • Deadhead spent flowers by pinching or cutting off the faded blooms. This encourages continuous reblooming.
  • Cut each flower stem down to the nearest set of healthy leaves or lateral bud.
  • Deadhead frequently, at least twice a week during peak flowering.

Pest and Disease Control

  • Helenium is pest and disease resistant when provided good growing conditions.
  • Avoid overcrowding to allow for good air circulation and prevent mold or mildew.
  • Treat aphids, spider mites, or other common pests with insecticidal soap as needed.
  • Remove any diseased foliage immediately and destroy it (do not compost it).
  • Improve drainage and reduce irrigation if you notice crown rot.

Propagating Helenium ‘Moerheim Beauty’

Helenium ‘Moerheim Beauty’ can be easily propagated by division, stem cuttings, or seed:

Division

  • Divide established clumps every 2-3 years in early spring before new growth begins.
  • Carefully dig up the plant and separate it into smaller sections, ensuring each division has some roots and shoots.
  • Replant the divisions 12-18 inches apart. Water well until established.

Stem Cuttings

  • Take 4-6 inch cuttings from healthy stems in early summer. Remove the bottom leaves.
  • Dip the cut end in rooting hormone to stimulate root growth.
  • Plant in pots with well-draining potting mix. Keep consistently moist until roots form.

Seeds

  • Collect dried seed heads and remove the seeds in late summer or fall. Store in a cool, dry place over winter.
  • Start seeds indoors 6-8 weeks before your last spring frost date. Barely cover with soil and keep moist.
  • Transplant outdoors once frost risk has passed and seedlings have 2-4 true leaves.

Designing With Helenium ‘Moerheim Beauty’

With its bold yellow colour, Helenium ‘Moerheim Beauty’ makes a big statement in the garden. Here are some tips for incorporating it into your landscape design:

Companion Planting

  • Combine it with cool blue flowers like Ageratum, Rozanne Salvia, or Russian Sage. The blue creates a nice contrast against the golden yellow.
  • Underplant it with lower growing perennials like coral bells, catmint, or lavender. This highlights the tall flowers.
  • Grow it alongside other late summer bloomers like echinacea, rudbeckia, and sedum.

Placement in the Garden

  • Use Helenium ‘Moerheim Beauty’ as a thriller plant in borders or cutting gardens. It draws the eye with big, bold colour.
  • Plant it 2-3 feet from walkways or seating areas so the flowers can be admired up close.
  • Place it towards the back or middle of beds so it doesn’t overshadow other plants.

Use in Containers

  • Plant one Helenium in a medium to large planter alongside other flowers and foliage. It works well in mixed containers.
  • Choose wide, sturdy containers that can support the mature height of the plants.
  • Use a quality potting mix and provide consistent moisture when grown in pots. Monitor soil moisture closely.
