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 somewhere 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.
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 don?t 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.
