PLANTING and AFTERCARE GUIDE

Best Planting Time

Plant Erysimum ‘Winter Passion’ in spring, when the soil begins to warm, allowing the roots to establish well ahead of flowering. Alternatively, autumn planting gives Erysimum ‘Winter Passion’ time to settle before its next growth cycle.

Site Selection

Sunlight: Choose a bright location, as Erysimum performs best in full sun. Generous light encourages stronger flowering and a more compact habit.

Soil: Erysimum prefers free-draining soil. Good drainage prevents root problems and keeps the plant healthy. Mixing in organic matter such as compost improves soil structure and promotes long-term growth.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and equal in depth, giving Erysimum ‘Winter Passion’ ample room to establish.
2. Amend the Soil: Work compost or other organic matter into the planting area. This supports nutrient availability and enhances drainage.
3. Planting: Set Erysimum ‘Winter Passion’ at the same soil level as it was in its pot. Gently firm the soil around the roots to eliminate air pockets.
4. Watering After Planting: Water well after planting to help the soil settle. Ensure the area drains freely so excess water does not remain around the roots.

Watering Requirements

• Growing Season: Once established, Erysimum is naturally tolerant of dry periods. Water during extended dry spells, but allow the soil to dry slightly between waterings.
• Dormant Season: Reduce watering significantly. Only water sparingly if the soil becomes very dry.

Feeding

• Spring: Apply a balanced fertiliser at the start of the season to boost new growth and flower production.
• Mid-Summer: A light feed mid-season helps Erysimum ‘Winter Passion’ maintain vigour and prolong its flowering performance.

Pruning

• Deadheading: Regularly remove faded blooms to encourage repeat flowering and maintain a tidy shape.
• Autumn Pruning: After flowering finishes, trim lightly to maintain its compact form and support healthy growth the following year.

Mulching

• Spring: Apply a layer of mulch around the base to retain moisture, buffer soil temperature, and help suppress weeds.
• Winter: Mulching also protects root systems during colder periods and helps maintain soil structure.

Supporting the Plant

Erysimum ‘Winter Passion’ has a naturally upright and bushy structure. Staking is rarely necessary, but in very windy locations, a light support can be used to prevent stem damage.

Final Tips

Erysimum ‘Winter Passion’ is a reliable, low-maintenance perennial that adds depth, fragrance, and bold colour to borders and containers. Plant it in full sun, ensure good drainage, and follow consistent aftercare, and it will reward you with a long, vibrant flowering display year after year.
