PLANTING and AFTERCARE GUIDE

Best Planting Time

The best time to plant Erysimum ‘Plant World Lemon’ is in spring when the soil begins to warm, allowing roots to establish before flowering. Alternatively, early autumn planting also works well, giving your Erysimum time to settle before the next growing phase.

Site Selection

Sunlight: Choose a spot in full sun to encourage abundant flowering and compact, upright growth. Because Erysimum thrives in bright conditions, a sunny location will enhance both its colour and its fragrance.

Soil: Provide free-draining soil to avoid moisture buildup around the roots. Incorporating grit or compost improves drainage and helps create the ideal growing environment for Erysimum ‘Plant World Lemon’.

Planting Instructions

1. Prepare the Hole
   Start by digging a hole twice as wide as the root ball. This gives Erysimum ‘Plant World Lemon’ plenty of room for strong root development.
2. Soil Preparation
   Next, enrich and aerate the soil by mixing in organic matter or coarse grit.
3. Planting
   Then place the plant so the top of the root ball is level with the surrounding soil. After positioning, backfill gently and firm the soil to secure the plant.
4. Watering After Planting
   Finally, water thoroughly to settle the soil. Once established, Erysimum prefers moderate moisture and copes well with short dry periods.

Watering Requirements

Water occasionally during prolonged dry spells, allowing the soil to dry slightly between sessions. During winter dormancy, reduce watering significantly to prevent excess moisture and maintain the health of Erysimum ‘Plant World Lemon’.

Feeding

Apply a balanced fertiliser in early spring to boost fresh growth. Additionally, a light midsummer feed helps Erysimum ‘Plant World Lemon’ maintain vigour and extend its flowering window.

Pruning

Deadhead regularly to encourage continuous blooming and keep the plant tidy. After flowering, lightly trim to encourage compact new growth and prevent legginess.

Mulching

Apply a thin layer of mulch in spring to conserve moisture and suppress weeds. However, avoid piling mulch around the crown. A light winter mulch provides added protection while still keeping the free-draining conditions preferred by Erysimum.

Final Tips

Erysimum ‘Plant World Lemon’ is a hardy, low-maintenance perennial that rewards gardeners with sweetly scented, colour-shifting flowers from early spring into summer. With its compact habit, reliable performance, and love of sunny, well-drained conditions, this Erysimum is an excellent choice for gardens needing long-lasting colour and fragrance.
