PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The optimal time to plant Allium schoenoprasum (One Series) ‘Purple One’ is in the spring when the soil begins to warm. This timing helps the roots establish firmly before the blooming season, resulting in a robust and healthy plant.
Autumn: Alternatively, you can plant Allium schoenoprasum (One Series) ‘Purple One’ in early autumn. This allows the plant to settle before dormancy, encouraging better growth in the following spring.
Site Selection
Sunlight: Allium schoenoprasum (One Series) ‘Purple One’ thrives in full sun. Select a location that receives at least 6 hours of direct sunlight each day. This exposure promotes vigorous growth and enhances flower production.
Soil: Choose well-drained soil for Allium schoenoprasum (One Series) ‘Purple One’. This plant does not tolerate waterlogged conditions, so ensuring proper drainage is essential for preventing root rot. Incorporate organic matter like compost to improve soil quality and drainage.
Planting Instructions
Prepare the Hole: When planting Allium schoenoprasum (One Series) ‘Purple One’, dig a hole that is twice the width and the same depth as the root ball. This space allows the roots to spread and grow comfortably.
Soil Preparation: Mix compost or organic matter into the soil to enhance fertility and drainage. Allium benefits from nutrient-rich soil, promoting vigorous growth and abundant blooms.
Planting: Place the plant into the prepared hole, ensuring that the top of the root ball is level with the surrounding soil. Gently backfill the hole, firming the soil to remove any air pockets.
Watering After Planting: Water your Allium thoroughly after planting. This helps to settle the soil and encourages the roots to establish. Ensure the area drains well to avoid waterlogged conditions.
Watering Requirements
Growing Season: Once established, Allium schoenoprasum (One Series) ‘Purple One’ is drought-tolerant. Water moderately during dry spells, allowing the soil to dry out slightly between sessions. Avoid overwatering, as excessive moisture can lead to root problems.
Dormant Season: During the dormant season, reduce watering significantly. Only water if the soil becomes excessively dry, as Allium requires minimal moisture during this period.
Feeding
Spring: In early spring, apply a balanced fertiliser to give Allium schoenoprasum (One Series) ‘Purple One’ a strong start to the growing season. This will support healthy new growth and vibrant flowers.
Mid-Summer: A light feeding in mid-summer can encourage continued flowering and ensure that your Allium maintains its vigour throughout the blooming season.
Pruning
Deadheading: Regularly deadhead Allium schoenoprasum (One Series) ‘Purple One’ by removing spent flowers. This practice prolongs the blooming period, keeps the plant tidy, and encourages new flower production.
Autumn Pruning: After the last flowers have faded in autumn, cut back the plant to ground level. This prepares the plant for winter dormancy and promotes healthier growth in the following year.
Mulching
Spring: Apply a layer of mulch around the base of the plant in spring to retain soil moisture, suppress weeds, and regulate soil temperature. Use organic materials such as bark chips or compost for best results.
Winter: In winter, adding mulch around your Allium helps protect the roots from cold temperatures and prevents frost heaving, ensuring the plant survives through to the next growing season.
Supporting the Plant
Staking: Allium schoenoprasum (One Series) ‘Purple One’ typically has sturdy stems and a compact growth habit, so staking is rarely necessary. However, in particularly windy locations, consider staking to prevent damage.
Final Tips
Allium schoenoprasum (One Series) ‘Purple One’ is a low-maintenance perennial that offers vibrant colour and attracts pollinators throughout the growing season.
