PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The best time to plant Crocosmia x crocosmiiflora ‘Harlequin’ is in spring when the soil is beginning to warm. This allows the plant to establish strong roots before the growing season, ensuring healthy growth and vibrant blooms.
• Autumn: Alternatively, planting Crocosmia in early autumn gives it time to settle into the ground before the colder months. This encourages robust growth when the plant emerges in the spring.

Site Selection

• Sunlight: Crocosmia x crocosmiiflora ‘Harlequin’ flourishes in full sun to partial shade. Choose a location that receives at least 6 hours of direct sunlight each day for optimal growth and flower production.
• Soil: This crocosmia variety prefers well-drained soil, as it does not tolerate waterlogged conditions. Enrich the soil with organic matter like compost to improve drainage and fertility, ensuring healthy root development and robust blooming.

Planting Instructions

1. Prepare the Hole: Dig a hole that is twice the width and depth of the root ball of Crocosmia x crocosmiiflora ‘Harlequin’. This provides ample space for the roots to spread out.
2. Soil Preparation: Incorporate compost or organic matter into the soil to boost its fertility and drainage. Crocosmia thrives in nutrient-rich soil.
3. Planting: Position the plant in the hole so that the top of the root ball is level with the surrounding soil. Backfill gently, firming the soil to eliminate air pockets.
4. Watering After Planting: Water the plant thoroughly to help settle the soil around the roots. Ensure the soil drains well to prevent waterlogging.

Watering Requirements

• Growing Season: Crocosmia is moderately drought-tolerant once established. Water during dry spells, allowing the soil to dry out slightly between watering sessions. Avoid overwatering, as excess moisture can lead to root rot.
• Dormant Season: During the dormant period, reduce watering significantly. Only water if the soil becomes excessively dry, as Crocosmia x crocosmiiflora ‘Harlequin’ requires minimal moisture in winter.

Feeding

• Spring: In early spring, apply a balanced fertiliser to encourage strong new growth and vibrant blooms for Crocosmia x crocosmiiflora ‘Harlequin’.
• Mid-Summer: A light feed in mid-summer helps promote continuous flowering throughout the growing season and supports the plant’s overall health.

Pruning

• Deadheading: Remove spent flowers regularly to extend the blooming period and prevent the plant from diverting energy into seed production. This also keeps your Crocosmia x crocosmiiflora ‘Harlequin’ plant tidy.
• Autumn Pruning: After flowering, cut the plant back to ground level. This will prepare it for the dormant season and promote healthier growth in the following year.

Mulching

• Spring: Apply a layer of mulch around your Crocosmia x crocosmiiflora ‘Harlequin’ in spring to help retain moisture, suppress weeds, and regulate soil temperature.
• Winter: Adding a layer of mulch around the base of the plant during winter helps protect the roots from frost and ensures the plant survives the colder months.

Supporting the Plant

• Staking: Crocosmia x crocosmiiflora ‘Harlequin’ typically has sturdy stems, but if grown in windy locations, consider staking to support the plant and prevent wind damage.
