PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The ideal time to plant Coreopsis ‘Sunstar Rose’ is in spring when the soil has started to warm. This allows the roots to establish before the peak blooming season.
Autumn: Alternatively, planting in early autumn gives the plant time to settle before dormancy, leading to stronger growth the following year.
Site Selection
Sunlight: Coreopsis ‘Sunstar Rose’ thrives in full sun, requiring at least six hours of direct sunlight daily for optimal flowering.
Soil: Well-drained soil is essential for Coreopsis ‘Sunstar Rose’ to prevent root rot. Enhance the soil with organic matter such as compost to improve fertility and drainage.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide as the root ball and the same depth to allow room for root expansion.
Soil Preparation: Mix compost or well-rotted manure into the soil to enhance nutrients and aeration.
Planting: Position the plant so the top of the root ball is level with the surrounding soil. Backfill gently, firming the soil around the base.
Watering After Planting: Water thoroughly to help establish the roots, ensuring the soil is moist but not waterlogged.
Watering Requirements
Growing Season: Once established, Coreopsis ‘Sunstar Rose’ is drought-tolerant. Water occasionally during prolonged dry spells, allowing the soil to dry out slightly between watering sessions.
Dormant Season: Reduce watering in colder months, only providing moisture if the soil becomes excessively dry.
Feeding
Spring: Apply a balanced fertiliser at the start of the growing season to promote strong growth and abundant flowering.
Mid-Summer: A light feed mid-season supports continuous blooming and plant vigour.
Pruning & Deadheading
Deadheading: Regularly remove spent flowers to prolong the blooming period and encourage fresh growth.
Autumn Pruning: After flowering has finished in late autumn, trim the plant back to ground level to prepare for winter dormancy.
Mulching
Spring: Apply a layer of organic mulch around the base to retain moisture, suppress weeds, and regulate soil temperature.
Winter: A protective mulch layer helps insulate the roots against colder temperatures and prevents frost damage.
Supporting the Plant
Coreopsis ‘Sunstar Rose’ has a naturally bushy and compact habit, reducing the need for staking. However, if grown in particularly windy locations, providing light support may help prevent stem breakage.
