PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The best time to plant Dahlia ‘Clarion’ is in spring when the risk of frost has passed. This ensures strong root establishment before the blooming season.
Late Spring to Early Summer: If planting later, ensure soil temperatures are warm enough to encourage tuber growth and healthy foliage development.
Site Selection
Sunlight: Dahlia ‘Clarion’ thrives in full sun. Choose a location that receives at least 6 hours of direct sunlight daily for maximum flowering potential.
Soil: Well-drained, fertile soil is essential for Dahlia ‘Clarion’. Avoid heavy, waterlogged soil by incorporating compost or organic matter to improve drainage and fertility.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide and as deep as the tuber or root ball to allow proper root spread.
Soil Preparation: Mix in compost or well-rotted manure to boost nutrients. This promotes strong stems and vibrant blooms for Dahlia ‘Clarion’.
Planting: Place the tuber horizontally with the eye facing upwards about 10-15 cm deep. Backfill with soil, gently firming it around the tuber.
Watering After Planting: Water thoroughly after planting to settle the soil and kickstart growth. Ensure the area drains well to prevent rot.
Watering Requirements
Growing Season: Water Dahlia ‘Clarion’ deeply 2-3 times per week, allowing the soil to dry slightly between waterings. Overwatering can lead to root rot.
Drought Periods: Increase watering during prolonged dry spells but avoid soaking the soil excessively.
Feeding
Early Growth: Apply a balanced liquid fertilizer every two weeks as Dahlia ‘Clarion’ begins active growth.
Budding & Flowering: Switch to a high-potassium feed (such as tomato fertilizer) to encourage abundant flowering.
Pruning & Deadheading
Deadheading: Regularly remove spent flowers to prolong blooming and maintain the plant’s tidy appearance.
Mid-Season Pruning: Pinch back early growth to encourage bushier plants and more flowers throughout the season.
Mulching
Spring & Summer: Apply a layer of mulch around the base of Dahlia ‘Clarion’ to retain moisture and suppress weeds.
Autumn & Winter: In colder months, mulch with straw or compost to protect tubers from frost damage.
Supporting the Plant
Staking: Due to its height of up to 1m, Dahlia ‘Clarion’ benefits from staking to support stems against wind or heavy rainfall.
Tying: Use soft ties to secure stems to stakes without damaging the plant.
Overwintering
In Mild Climates: Leave tubers in the ground but cover with a thick layer of mulch for insulation.
In Colder Climates: Lift tubers after the first frost, dry them for a few days, then store in a cool, dry place over winter.
Final Tips
Dahlia ‘Clarion’ is a show-stopping addition to any garden with its bright yellow blooms and dark foliage. By providing full sun, well-drained soil, and proper care, Dahlia ‘Clarion’ will reward you with stunning flowers from summer to autumn. Whether grown in borders or containers, Dahlia ‘Clarion’ will enhance any outdoor space with its striking contrast and long-lasting blooms.
