PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Rudbeckia hirta ‘Enchanted Cosmic Eye’ in spring as the soil begins to warm. This gives roots time to establish ahead of the flowering season.
Early Autumn: Alternatively, plant in early autumn, giving the plant time to settle before entering dormancy, leading to vigorous growth in the next season.
Site Selection
Sunlight: Rudbeckia hirta ‘Enchanted Cosmic Eye’ thrives in full sun. Choose a spot that receives at least 6 hours of direct sunlight daily for optimal flower production.
Soil: Ensure moist, well-drained soil. Avoid waterlogged conditions, which can cause root rot. Adding compost or organic matter helps improve drainage and soil fertility.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide and equal in depth to the root ball of Rudbeckia hirta ‘Enchanted Cosmic Eye’.
Improve Soil: Mix compost or organic material into the planting area to boost nutrients and drainage.
Position the Plant: Place the plant in the hole with the top of the root ball level with the surrounding soil.
Backfill and Water: Fill in the hole, gently firming the soil to eliminate air pockets. Water thoroughly after planting to help roots establish.
Watering Requirements
Active Growth Season: Water regularly during dry spells, allowing the top layer of soil to dry out slightly between watering.
Dormant Season: Reduce watering significantly. Only water if the soil becomes very dry, as the plant needs little moisture during dormancy.
Feeding
Spring: Apply a general-purpose fertiliser in spring to support early growth and encourage strong stems and flower buds.
Mid-Summer: A second light feeding mid-season can prolong blooming and maintain plant vigour.
Pruning and Deadheading
Deadheading: Regularly remove spent blooms from Rudbeckia hirta ‘Enchanted Cosmic Eye’ to promote continuous flowering and a tidy appearance.
Autumn Cutback: Once flowering is complete, cut the plant back to the base to prepare it for winter and stimulate fresh growth next season.
Mulching
Spring: Apply mulch such as bark or compost around the base to conserve moisture, suppress weeds, and regulate soil temperature.
Winter: Mulch again in winter to insulate roots and prevent frost damage.
Supporting the Plant
While Rudbeckia hirta ‘Enchanted Cosmic Eye’ generally maintains a sturdy structure, you may choose to stake taller plants in exposed areas to prevent wind damage and keep stems upright.
