How to Grow
Planting: Plant 'Kelvin Floodlight' dahlia tubers in spring after the risk of frost has passed. Choose a sunny, sheltered spot with well-drained, fertile soil. Position the tubers about 10-15cm deep with the “eye” or growth point facing upwards, and space them around 60cm apart to allow for their large size and spread.
Watering: Water thoroughly after planting to help the tubers establish. Once shoots appear, water regularly to keep the soil moist but not waterlogged. During dry or hot weather, deep watering once or twice a week is beneficial for promoting large, healthy blooms.
Feeding: Feed with a high-potassium fertiliser, such as tomato feed, every two weeks once flowering begins. This will support the large blooms and keep the plant healthy and vigorous throughout the season.
Staking: Due to its large flower heads, 'Kelvin Floodlight' benefits from staking to keep the stems upright and prevent bending. Insert sturdy stakes at planting time to avoid disturbing the tubers, and loosely tie the stems to the supports as they grow.
Deadheading and Maintenance: Remove spent blooms regularly to encourage continuous flowering. This will also keep the plant looking tidy and healthy. After the first frost, cut back the foliage, and either lift and store the tubers or apply a layer of mulch if you prefer to leave them in the ground over winter.
Overwintering: In colder UK regions, it’s best to lift and store dahlia tubers after the first frost. Allow them to dry, then store them in a cool, frost-free place in slightly damp compost until replanting in spring. In milder areas, you may leave the tubers in the ground with a protective layer of mulch.
With its show-stopping, giant yellow blooms and easy-to-grow nature, Dahlia 'Kelvin Floodlight' is a fantastic choice for adding drama, warmth, and vibrant colour to UK gardens. Perfect for garden displays and impressive cut flower arrangements, this variety brings spectacular beauty and cheer to any outdoor space from summer to autumn.
