PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Agapanthus ‘Darkest of All’ in early spring, when the soil begins to warm. This allows the roots to establish well and supports robust growth during the active growing season.
• Autumn: Alternatively, plant in autumn to give Agapanthus ‘Darkest of All’ time to settle before the dormant period. This will help the plant start strong in the following spring.

Site Selection

• Sunlight: Choose a location that receives full sun for at least 6 hours daily. Agapanthus ‘Darkest of All’ thrives in sunny conditions, which promote abundant flowering and healthy growth.
• Soil: Well-drained soil is essential for Agapanthus ‘Darkest of All’ to prevent water-logging, which can lead to root rot. Although it adapts to different soil types, good drainage is crucial for its longevity and performance.

Planting Instructions

1. Preparing the Hole: Dig a hole twice as wide and the same depth as the root ball of Agapanthus ‘Darkest of All’. This provides enough space for the roots to expand and establish.
2. Soil Preparation: Improve soil quality by mixing in compost or organic matter. This enhances drainage and provides essential nutrients to support healthy root development.
3. Planting: Place Agapanthus ‘Darkest of All’ in the hole, ensuring the top of the root ball is level with the surrounding soil. Backfill gently, pressing the soil to remove any air pockets.
4. Watering: Water thoroughly after planting to help settle the soil around the roots and encourage establishment.

Watering

• Growing Season: Once established, Agapanthus ‘Darkest of All’ is relatively drought tolerant. Water moderately during dry periods to maintain healthy growth and vibrant flowers.
• Dormant Season: Reduce watering as the plant enters dormancy, ensuring the soil remains slightly moist but not waterlogged to prevent root damage.

Feeding

• Spring: Apply a balanced fertiliser in early spring to support new growth and enhance the flowering of Agapanthus ‘Darkest of All’.
• Mid-Summer: A light mid-summer feed will provide additional nutrients, promoting prolonged blooming and healthy foliage.

Pruning

• Deadheading: Remove spent flower stalks regularly to encourage continuous blooming and to keep Agapanthus ‘Darkest of All’ looking tidy and attractive.
• Autumn: After the final bloom, cut back the foliage to ground level. This will help the plant conserve energy and prepare for dormancy.

Mulching

• Spring: Apply mulch around the base of Agapanthus ‘Darkest of All’ to retain soil moisture, suppress weeds, and regulate soil temperature.
• Winter: Mulch again in winter to protect the roots from colder temperatures and provide extra insulation.

Supporting the Plant

• Staking: Agapanthus ‘Darkest of All’ generally has sturdy stems but may benefit from staking in exposed or windy areas to prevent bending or damage.
