PLANTING and AFTERCARE GUIDE

Best Planting Time

Spring: The best time to plant Agapanthus ‘Super Star’ is in spring, once the soil has warmed up. This gives the plant the optimal conditions for root development and growth.

Autumn: Alternatively, planting your Agapanthus in early autumn allows it to establish before winter and ensures it will be ready to thrive in the next growing season.

Site Selection

Sunlight: Agapanthus ‘Super Star’ thrives in full sun, needing at least 6 hours of direct sunlight per day. A sunny location will encourage the best flowering display and ensure healthy growth.

Soil: This plant prefers well-drained soil to prevent water logging, which can lead to root rot. Agapanthus is adaptable to different soil types but flourishes best in fertile, moderately moist soil with excellent drainage.

Planting Instructions

1. Prepare the Site: Start by digging a hole that is twice as wide and the same depth as the root ball of the plant . This ensures the roots have ample space to spread out.
2. Soil Preparation: To boost growth, mix in some compost or organic matter into the soil. This will improve soil fertility and structure, giving your Agapanthus a strong start.
3. Planting: Position the plant in the hole, making sure the crown of Agapanthus ‘Super Star’ sits at soil level. Fill the hole back in with soil and press down gently to remove air pockets.
4. Watering: Water thoroughly after planting to help settle the soil and begin the root establishment process.

Watering Needs

Growing Season: Agapanthus ‘Super Star’ is relatively drought-tolerant once established, but regular watering during dry periods is essential for promoting continuous blooming. Keep the soil moist but not waterlogged during its growing phase.

Dormant Season: In the dormant months, reduce watering to avoid soggy soil conditions. Agapanthus requires less moisture during this period, but make sure the soil doesn’t completely dry out.

Feeding

Spring: Feed Agapanthus ‘Super Star’ with a balanced, slow-release fertiliser at the beginning of spring to encourage healthy growth and vibrant blooms. A fertiliser rich in phosphorus will promote excellent flower production.

Mid-Summer: If the flowers start to slow down, you can apply a light feed mid-summer to boost its energy and encourage a fresh round of blooms.

Pruning and Maintenance

1. Deadheading: Remove spent flowers regularly to encourage further blooming and keep the plant looking tidy.
2. Autumn Pruning: After flowering finishes, cut back the foliage to help the plant conserve energy for the next growing season. This also keeps the plant neat throughout winter.

Mulching

Spring: Apply a layer of organic mulch around the base of the plant in early spring to conserve soil moisture, suppress weeds, and regulate soil temperature. This also helps to create the ideal environment for root growth.

Winter: In areas where frost is common, adding an extra layer of mulch in late autumn can protect the roots from cold damage, ensuring that Agapanthus ‘Super Star’ survives the winter months.

Supporting the Plant

Agapanthus ‘Super Star’ generally does not require staking, as its stems are quite sturdy. However, if grown in windy areas or where the soil is particularly loose, providing a little support may help prevent the tall stems from bending or snapping.

Final Tips for Success

Agapanthus ‘Super Star’ is a low-maintenance perennial that rewards minimal effort with a long season of beautiful, deep blue blooms. Ensure your Agapanthus receives full sun, is planted in well-drained soil, and gets adequate water during the growing season. With the right care, Agapanthus ‘Super Star’ will continue to thrive, adding striking colour and texture to your garden year after year.
