PLANTING and AFTERCARE GUIDE

Best Planting Time

Plant when the soil naturally begins to warm or retains gentle warmth, as this encourages strong early root establishment and supports vigorous growth before flowering begins.

Site Selection

• Sunlight: Choose a position with full sun or partial shade, as this helps Geranium pratense ‘Purple Ghost’ produce abundant flowers while maintaining its dark, dramatic foliage. Additionally, adequate light promotes sturdy stems and balanced growth.
• Soil: Geranium thrives in well-drained, moderately fertile soil. Improve compacted or heavy areas with compost or grit, which consequently boosts drainage and allows the roots to develop fully and healthily.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and equal in depth, ensuring Geranium pratense ‘Purple Ghost’ has ample room to establish its roots.
2. Soil Preparation: Mix compost or organic matter into the soil to improve fertility and structure, thus supporting better establishment and long-term growth.
3. Planting: Position Geranium pratense ‘Purple Ghost’ with the top of the root ball level with the surrounding soil, then gently backfill and firm to remove any trapped air pockets.
4. Watering After Planting: Water thoroughly to settle the soil around the roots and help moisture reach the root zone without creating waterlogging.

Watering Requirements

• Growing Season: Water moderately, allowing the soil surface to dry slightly between waterings. Since Geranium prefers good drainage, this helps prevent excess moisture and supports continuous flowering.
• Dormant Period: Water sparingly and only when the soil becomes noticeably dry, allowing the plant’s natural resting phase to continue without unnecessary root saturation.

Feeding

• Spring: Apply a balanced fertiliser to encourage strong early foliage and healthy flower production, setting up for a successful season.
• Mid-Summer: A light supplementary feed helps maintain vigour and supports ongoing blooms throughout the summer months.

Pruning

• Deadheading: Remove faded flowers regularly to promote continuous blooming and keep your Geranium looking tidy. Deadheading redirects energy into producing fresh buds.
• Seasonal Cutting Back: After peak flowering, trim back stems lightly to refresh the plant and encourage neat, compact regrowth.

Mulching

• Spring Mulch: Apply a thin layer of organic mulch to help retain moisture, suppress weeds and improve soil structure around Geranium pratense ‘Purple Ghost’.

Supporting the Plant

Growing to around 20 cm tall with a 40 cm spread, Geranium typically remains compact, although light support may be useful in more exposed sites to prevent stems from leaning.

Final Tips

Geranium pratense ‘Purple Ghost’ is a hardy, low-maintenance perennial offering strong colour contrast, elegant flowers and excellent seasonal performance. By planting it in a well-drained, brightly lit position, watering moderately and feeding occasionally, you will enjoy months of striking foliage and fresh white blooms. With minimal care, Geranium pratense ‘Purple Ghost’ becomes a stunning highlight in any garden year after year.
