Product Information

While you may have a perception of dahlias as being old-fashioned, and something that your grandad grew when you were younger, they have actually been enjoying a renaissance over the last few years, mainly because they provide such stunning colour and value for money in the late summer and autumn.

So easy to grow, Dahlias are supplied as tubers, packed full of energy to burst into growth in spring. Plant in pots or in the garden and they will get away quickly from May, producing a mass of bright colours which will fill your garden as summer turns to autumn.

Our collection of cactus dahlias will give you large, double blooms with narrow, spiky petals and each pack provides 5 mixed colour tubers, which will reach around a metre tall, and produce plenty of flowers each. These can be cut for the house, or left to enjoy outdoors. Dead-heading will prolong flowering well into autumn. Plants will survive milder winters, but we recommend lifting the tubers and storing somewere dry and frost-free over winter, or left in pots if that's how you choose to grow them.

These blousy Dahlias make a great addition to any autumn garden and their blooms will bring colour as everything else starts to fade.

Top Tips

  • When the plants flower, you will notice one large central bud and two, smaller side buds.
  • You can either remove the side buds to get one large flower or keep them to get three flowers which will be smaller.
  • Dahlias are fairly hardy, although frost-tender perennials and during mild winters they will overwinter successfully under a heavy mulch.
  • However, we do recommend where possible that tubers are lifted in the autumn and dried upside down before storing in a frost-free place over the winter.
  • Stored tubers can then be started back into growth the following spring before planting back out.
  • If you find that earwigs are a problem, the organic way to control them is to position pots filled with straw upside down on canes spaced around your dahlias.

Care Information

  • Dahlias are tender tubers and do best when potted up initially in March or early April, into large pots (2 - 3L) filled with multi-purpose compost.
  • Placed in a light, frost-free place and kept moist, they'll quickly form bushy plants by the time the frosts have ended, ready to be planted out into the garden.
  • In the garden, dig a hole at least 30cm wide x 30cm deep for each one, spacing each tuber 75cm apart.
  • If you donít have anywhere to start them in pots, you can put the tubers straight into the ground when the frosts are nearly over.
  • Once a fortnight, feed them with a liquid feed such as our Blooming Fast Superior plant feed. During dry periods, water at least once a week.
  • Dahlias should be deadheaded regularly to encourage more blooms and you will need to stake the plants to prevent the flowers from breaking the stems.
