How to grow the Rudbeckia ‘Goldsturm’

Soil and Feeding

Rudbeckia ‘Goldsturm’ thrives in well-draining, moderately fertile soil. While it can adapt to various soil types, it prefers a slightly acidic to neutral pH (6.0-7.0). To improve drainage and fertility, incorporate organic matter such as compost into the planting area.

Feed ‘Goldsturm’ annually in spring with a balanced, slow-release fertiliser. Avoid over-fertilising, as this can lead to excessive foliage growth at the expense of flowers. In poor soils, a light top-dressing of compost in spring can provide additional nutrients.

Watering

While established plants are relatively drought-tolerant, regular watering during the first growing season is crucial for developing a strong root system. Water deeply once or twice a week, depending on rainfall and soil conditions. Once established, Rudbeckia ‘Goldsturm’ can tolerate short dry spells but benefits from consistent moisture during hot, dry periods.

Avoid overwatering, as this can lead to root rot and fungal diseases. Ensure good air circulation around plants to prevent foliar diseases.

Pruning

Pruning Rudbeckia ‘Goldsturm’ serves several purposes: maintaining plant shape, encouraging reblooming, and preparing for winter.

  1. Deadheading: Remove spent flowers regularly during the flowering season to encourage continued flowering and prevent self-seeding.
  2. Mid-season pruning: If plants become leggy, cut them back by about one-third in midsummer to promote bushier growth and a second flush of blooms.
  3. Winter preparation: In late autumn or early winter, cut back the stems to about 10-15 cm above ground level. Alternatively, leave the seed-heads for winter interest and bird food, cutting back in late winter or early spring before new growth emerges.

Propagation

The most common method of propagating Rudbeckia ‘Goldsturm’ is through division. Here’s a step-by-step guide:

  1. Divide plants in early spring or autumn.
  2. Water the plant thoroughly the day before dividing.
  3. Dig up the entire clump, preserving as much of the root system as possible.
  4. Gently separate the clump into smaller sections, ensuring each division has several healthy shoots and roots.
  5. Replant the divisions at the same depth as the original plant, spacing them 45-60 cm apart.
  6. Water well and keep the soil consistently moist until new growth appears.

Common Problems & Solutions

  • Powdery mildew: White, powdery coating on leaves. Improve air circulation and avoid overhead watering. Apply fungicides if severe.
  • Leaf spot diseases: Dark spots on leaves. Remove affected foliage, improve air circulation, and avoid overhead watering.
  • Verticillium wilt: Yellowing and wilting of leaves. Remove and destroy affected plants, as there is no cure.
  • Aphids: Tiny insects that suck plant sap. Control with insecticidal soap or a strong spray of water.
  • Japanese beetles: Chewing damage on leaves and flowers. Handpick beetles or use pheromone traps.
  • Slugs and snails: Holes in leaves, especially on young plants. Use beer traps or organic slug pellets.
  • Aster yellows: Stunted, yellowed growth and deformed flowers. Remove and destroy affected plants to prevent spread.

By following these guidelines, you can successfully grow and enjoy the vibrant beauty of Rudbeckia ‘Goldsturm’ in your garden.
