PLANTING and AFTERCARE GUIDE

Best Planting Time

The ideal time to plant Erysimum ‘Rysi Moon’ is in spring when the soil begins to warm, helping the roots establish before flowering. Alternatively, early autumn planting works well, allowing time to settle and prepare for next season’s growth.

Site Selection

Sunlight: Choose a position in full sun to encourage abundant flowering and strong, compact growth. Since Erysimum thrives in bright, sunny sites, this helps enhance its creamy bloom colour and delicate scent.

Soil: Ensure free-draining soil to avoid excess moisture around the roots. Incorporating grit or compost improves structure and creates ideal conditions for Erysimum ‘Rysi Moon’, promoting healthy and long-lasting performance.

Planting Instructions

1. Prepare the Hole
   Start by digging a hole twice the width of the root ball. This gives Erysimum ‘Rysi Moon’ plenty of space for robust root development.
2. Soil Preparation
   Next, mix organic matter or coarse grit into the soil to improve aeration and drainage.
3. Planting
   Then place the plant so the top of the root ball is level with the surrounding soil. After positioning, gently backfill and firm the soil around Erysimum ‘Rysi Moon’.
4. Watering After Planting
   Finally, water thoroughly to settle the soil. Once established, Erysimum prefers moderate moisture and can tolerate short periods of dryness.

Watering Requirements

Water occasionally during extended dry spells, allowing the soil to dry slightly between watering sessions. During its quieter growth periods, reduce watering to maintain the free-draining conditions that Erysimum prefers.

Feeding

Apply a balanced fertiliser in early spring to encourage fresh new growth. Additionally, a light midsummer feed helps maintain vigour and extend its flowering season.

Pruning

Deadhead regularly to encourage continuous blooming and to keep the plant neat. After flowering, lightly trim your Erysimum to promote compact new growth and prevent the stems from becoming leggy.

Mulching

In spring, apply a thin layer of mulch to help retain moisture and suppress weeds. However, avoid piling mulch directly against the crown. A light winter mulch can protect the roots while keeping soil conditions free-draining for Erysimum ‘Rysi Moon’.

Final Tips

Erysimum ‘Rysi Moon’ is a hardy, low-maintenance perennial that offers months of elegant, scented blooms from April to September. With its compact form, refined colouring, and preference for sunny, free-draining soil, ‘Rysi Moon’ is a perfect choice for gardens seeking soft seasonal beauty and reliable, long-lasting floral displays.
