PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Agapanthus ‘Nocturnal Horizons’ in early spring when the soil is warming, allowing roots to establish before the flowering season.
• Autumn: Alternatively, planting in autumn helps the roots settle before the colder months, ensuring a strong start to the growing season.

Site Selection

• Sunlight: Agapanthus ‘Nocturnal Horizons’ prefers full sun for optimal blooming. Ensure it receives at least 6 hours of direct sunlight daily to promote vibrant flower production.
• Soil: This variety flourishes in well-drained soil. To prevent waterlogging, especially in heavy soil, amend the planting area with grit or compost to improve drainage and soil structure.

Planting Instructions

1. Preparing the Hole: Dig a hole twice as wide and as deep as the root ball of Agapanthus ‘Nocturnal Horizons’ to allow ample space for the roots to spread.
2. Soil Preparation: Mix organic matter, such as compost, into the soil to enhance fertility and drainage.
3. Planting: Position the plant in the hole so that the top of the root ball is level with the surrounding soil. Fill in around the root ball, firming the soil gently to eliminate air pockets.
4. Watering: Water thoroughly after planting to help settle the soil and initiate root establishment.

Watering

• Growing Season: Agapanthus ‘Nocturnal Horizons’ requires regular watering during the growing season. Keep the soil evenly moist but not waterlogged. Water more frequently during dry periods to maintain healthy growth and flower production.
• Dormant Season: Reduce watering in late autumn and winter. The soil should remain slightly moist but not saturated, as excessive moisture can cause root rot.

Feeding

• Spring: Apply a balanced fertiliser in early spring to support new growth and enhance the development of Agapanthus ‘Nocturnal Horizons’ flower buds.
• Mid-Summer: A second, lighter feeding in mid-summer will encourage continuous blooming throughout the season.

Pruning

• Deadheading: Remove spent flowers regularly to promote prolonged blooming and keep Agapanthus ‘Nocturnal Horizons’ looking tidy.
• Autumn: After the final bloom, cut back the stems and foliage to ground level to prepare the plant for its dormant period.

Mulching

• Spring: Apply a layer of mulch around the base of Agapanthus ‘Nocturnal Horizons’ in spring to retain moisture, suppress weeds, and regulate soil temperature.
• Autumn: Add an additional layer of mulch in autumn to protect the crown and roots during the cooler months.

Supporting the Plant

Agapanthus ‘Nocturnal Horizons’ generally has sturdy stems, but in areas prone to strong winds, staking may be necessary to prevent bending or breakage of flower stems.

With proper care, Agapanthus ‘Nocturnal Horizons’ will thrive and deliver beautiful displays for many years.
