Watermelon pink petals with a blush of apricot. Big cactus type blooms that are sure to impress.

Big is beautiful! Giant Dahlias are BIG! I measure them against my grandchildren’s smiling faces and their grins are sometimes eclipsed by the petals! Very impressive. The stems are strong but the blooms are heavy so they should be staked.
Dahlias are an absolute delight. They are easy to care for and bring you masses of vibrant flowers. What’s more, they can be left to colour your garden or bought inside to decorate your home. In fact, Dahlias have so many flowers, it is easy to do both! Dahlia flowers bloom summer to autumn or, from around December to April.
Dahlias take around eight weeks from planting to flowering. It is best to plant Dahlias in a sunny spot, morning sun is best and they will need around six hours sun a day to flower well.

Plant Dahlias into moist, humus rich, well drained soil. We recommend digging well rotted manure though the soil prior to planting. Plant the tuber around 10cm deep, and it is a good idea to stake tall varieties at the time of planting, this avoids root disturbance later on. Allow for good air flow between the plants.

You don’t need to water your Dahlias in, just keep them moist once they start to grow. Add a slow release tomato fertiliser in early summer and some Sulphate of Potash, then mulch for best results.

Dahlia flowers are excellent for cutting, and last well in a vase. By cutting the flowers you will also encourage more blooms. When you cut the flowers, it is a good idea to do it in the morning as they have a higher moisture content and so will last longer. Cut the stems so you are taking at least two leaves, this prunes the plant back far enough to encourage more flowers and bushy growth. Any spent flowers left on the plant should be removed as they brown in a similar method to encourage more blooms.

Dahlia tubers don’t really need to be lifted, if the soil is well drained and you don’t live in areas where the soil will freeze. But they should be dug and divided every couple of years to keep them flowering at their best.

Dahlias were discovered in Mexico in the 1700’s. They were named after the Swedish botanist, Anders Dahl.
