PLANTING & AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Geranium ‘Sweet Heidy’ in spring when soil is naturally warming, helping the plant establish strong roots before its long flowering season begins.
• Autumn: Planting in early autumn allows time for root development before the plant enters its resting period.

Site Selection

• Sunlight: Geranium ‘Sweet Heidy’ flourishes in full sun to partial shade. Choose a bright position to encourage abundant blooms and compact, healthy growth.
• Soil: Ensure the soil is moist yet well-drained. Geranium dislikes heavy, saturated soil, so improve drainage with compost or organic matter if needed.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width of the root ball and the same depth. This gives Geranium ‘Sweet Heidy’ plenty of room for root expansion.
2. Soil Preparation: Blend compost or organic material into the planting area to enrich the soil and improve drainage.
3. Planting: Set the plant into the hole so the top of the root ball sits level with the surrounding soil. Backfill gently and firm the soil around the base.
4. Watering After Planting: Water thoroughly to settle the soil and support early root establishment.

Watering Requirements

• Growing Season: Geranium benefits from moderate watering, especially during prolonged dry spells. Allow the soil surface to dry slightly between watering sessions.
• Dormant Season: Reduce watering significantly, providing moisture only when the soil becomes very dry.

Feeding

• Spring: Apply a balanced fertiliser in spring to boost new growth and support generous flowering.
• Mid-Summer: A light feed mid-season helps Geranium ‘Sweet Heidy’ maintain its impressive flowering display into late autumn.

Pruning

• Deadheading: Remove spent flowers regularly to prolong blooming and maintain a tidy plant. Geranium responds well to this, producing even more flowers.
• Autumn Pruning: After flowering ends, cut the plant back to ground level to encourage vigorous regrowth the following year.

Mulching

• Spring: Add a mulch layer around Geranium ‘Sweet Heidy’ to keep moisture in, prevent weeds, and stabilise soil temperature.
• Winter: Applying mulch in winter offers additional protection for the roots and helps the plant overwinter successfully.

Supporting the Plant

Geranium typically maintains a compact and sturdy growth habit. In exposed or windy areas, light support can be added, although staking is rarely required.

Final Tips
