PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Dianthus ‘Red Carpet’ in spring to give roots time to establish before flowering begins.
Autumn: Early autumn planting is also effective, allowing the plant to settle and prepare for vigorous growth the following season.
Site Selection
Sunlight: Dianthus ‘Red Carpet’ flourishes in full sun, producing the brightest blooms and strongest fragrance. Choose a location that receives at least 6 hours of direct sunlight per day.
Soil: Well-drained soil is essential. If your soil is heavy or clay-like, mix in compost or grit to improve drainage and prevent root rot.
Planting Instructions
Prepare the Hole: Dig a hole twice the width of the root ball and the same depth to give Dianthus ‘Red Carpet’ ample room for root expansion.
Soil Preparation: Enrich the planting soil with compost or organic matter to improve fertility and drainage.
Planting: Place the plant so that the crown sits level with the surrounding soil. Backfill gently and firm the soil around the roots to remove air pockets.
Watering After Planting: Water your Dianthus thoroughly after planting, ensuring excess water drains away.
Watering Requirements
Growing Season: Water during dry periods, allowing the soil to dry slightly between sessions. Avoid overwatering, as Dianthus prefers well-drained conditions.
Dormant Season: Reduce watering in colder months, only adding moisture if the soil becomes very dry.
Feeding
Spring: Apply a balanced fertiliser in early spring to encourage strong growth and prepare Dianthus ‘Red Carpet’ for flowering.
Mid-Summer: A light feed in mid-summer extends the flowering period and enhances colour and fragrance.
Pruning
Deadheading: Remove spent flowers regularly. Deadheading your Dianthus encourages continuous blooms and maintains a tidy appearance.
End of Season: After flowering, lightly trim back foliage to preserve shape and prepare the plant for the next season.
Mulching
Spring: Apply a thin layer of mulch around the base to conserve moisture, suppress weeds, and enrich the soil. Avoid covering the crown to prevent rot.
Winter: A light mulch can also protect the roots during colder months, helping Dianthus ‘Red Carpet’ remain healthy and hardy.
Supporting the Plant
Dianthus ‘Red Carpet’ has a compact and sturdy growth habit, so staking is rarely needed. In exposed areas, a small support may prevent wind damage.
Final Tips
Dianthus ‘Red Carpet’ is a low-maintenance perennial that brings vibrant crimson blooms and a wonderful scent to borders, beds, and containers. Plant in full sun with well-drained soil, feed lightly, deadhead regularly, and enjoy a continuous display of colour and fragrance throughout the summer.
