Description

PLANTING and AFTERCARE GUIDE

Best Planting Time

The ideal time to plant Erysimum ‘Winter Light’ is in spring, as this gives the root system ample opportunity to settle before its flowering period. Alternatively, early autumn planting also works well, allowing time to root in comfortably before the growing season begins.

Site Selection

For the best results, choose a sunny spot. Erysimum ‘Winter Light’ performs at its peak when given full sun, which promotes abundant flowering and helps maintain its compact shape. Additionally, ensure the soil is free-draining, as Erysimum dislikes sitting in moisture. Adding compost or grit can improve soil texture and prevent waterlogging.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and of equal depth. This gives Erysimum ‘Winter Light’ plenty of space to establish.
2. Improve the Soil: Work in organic matter to boost fertility and drainage.
3. Position the Plant: Place Erysimum ‘Winter Light’ so the top of the root ball sits level with the surrounding soil.
4. Backfill and Firm: Gently firm the soil around the plant, removing air pockets.
5. Water Thoroughly: Water well immediately after planting to settle the roots, ensuring the soil drains effectively.

Watering Requirements

Once established, Erysimum is naturally tolerant of drier periods. Water during prolonged dry spells, allowing the soil to dry slightly between waterings. Avoid overwatering, as excessive moisture can cause root stress.

Feeding

A balanced slow-release fertiliser applied in spring will support strong, healthy growth. Feeding again in midsummer can help maintain its vigour throughout its lengthy flowering period.

Pruning

Deadhead spent blooms regularly, which encourages fresh flowers and keeps Erysimum ‘Winter Light’ looking tidy. After flowering has finished for the season, lightly trim back to maintain its shape and promote new growth.

Mulching

Mulch around the base in spring to retain moisture, suppress weeds and create a more stable soil environment. Organic mulches, such as compost or bark, work particularly well. A winter mulch can also help protect the root system during colder spells.

Supporting the Plant

Erysimum ‘Winter Light’ typically forms a neat, bushy habit and rarely requires staking. However, in very exposed areas, a light support may prevent wind-related damage.

Final Tips

Erysimum ‘Winter Light’ is a rewarding, low-maintenance perennial that brings brightness and perfume to borders, gravel gardens and containers. By ensuring it receives full sun, well-drained soil and consistent seasonal care, this Erysimum will provide a long-lasting display of cheerful blooms from spring through summer.
