Dahlia, 'Duet' is a fabulous bicolour variety with deep red petals toward the heart of the bloom against crisp white at the tips. These are large, double flowers that are up to 5-6 inches wide. 'Duet' dahlia blooms in mid-summer and will produce flowers through the fall until frost! It's a vigorous grower with many blooms throughout the season. They look fantastic as part of a border and make exceptional cut flowers. By planting Dahlia 'Duet', you can expect butterflies and other pollinators flying around your garden or patio this Summer!

- 10 cm of soil on top of the bulb.
- Spacing 40 cm.
- Flowers from July until the first frost.
- Height 80 cm.
Half-hardy. Perennial. These bulbs cannot withstand freezing conditions or sitting in water. It is best to start the tubers in pots first, pot size needs to be around 4 ltr. Place the pots either in the greenhouse or somewhere that is frost-free. Once growing and free from cold weather then plant out into the garden. If you have well-drained soil, plant them deep and cover in the winter with mulch. Feed well throughout the growing season with a slow-release fertilizer. If your soil is heavy it is best to lift the tubers at first frost, cut the stems back leaving an inch. Store upside down in a frost-free environment, replant in April. Propagation: Divide the bulbs every couple of years.
There's no need to water the soil until the dahlia plants appear; in fact, overwatering can cause bulbs to rot. After dahlias are established, provide a deep watering 2 to 3 times a week for at least 30 minutes with a sprinkler (and more in dry, hot climates).
