Mixed dahlias for cutting are a hand mixed selection of dahlia tubers, perfect for growing your own cut flowers. There are 70,000 named dahlia varieties, ranging from very small bedding to the extremely large flowers of dinnerplate dahlias. Within our selection we have a collection of the main groups of dahlia. These are categorised as Decorative dahlia, Ball Dahlias, Pompom dahlia, Cactus dahlia and Single Dark Leaved dahlia.

The dahlia tubers are mixed in our warehouse from this season’s collection. We don’t use the bedding dahlias for the cutting mix as they can be too short.

You can use this collection as a mix and plant the tubers around the garden for an array of summer long colours. Or if your garden is carefully curated then many people choose a hidden section of the garden to grow cutting mixtures, a space purely designated for growing flowers for indoors.

Dahlias are the perfect plant for cutting. Cutting the flowers actively promotes the growth of more flowers.

Caring for your mixed dahlias for cutting

A few doses of low nitrogen fertiliser can also make a difference to the yield of flowers. Make sure the tubers are planted in a sunny and warm position and keep them well watered, they require a lot of water and a nice rich soil to flourish. The taller varieties will need staking once they reach a certain size. The stems, although strong, carry a lot of foliage and some of the larger flowers can be quite heavy. When planting out the tubers remember to position them around 40-50cm apart to allow for them to grow.

Many people choose to plant the tubers in pots from March and place them in a green house to protect from frosts and get an early start on the flowering time. Dahlias are not frost resistant, so they young plants are transferred to the garden in April or May after the tulips have finished.
Mixed dahlias will provide flowers from July to the first frosts,  continuously creating new flowers. They regenerate very quickly, so if a plant is damaged by aphids or slugs you can cut them back and they will return to splendour in a matter of weeks.

Lifting dahlia tubers

Lift the tubers in November and cut the stem down leaving 2 inches. Place in a well ventilated, dry and frost free environment ready for planting out the next year. You can attach a label with a rubber band to identify it, I have also seen people writing directly onto the tuber with a marker pen.
