  • Dahlia are upright growing, easy to grow bushy Summer flowering herbaceous perennial tubers. These half hardy impactful growing plants are popular in UK gardens because of their long flowering period, flowering from July until early November. With their vast range of colours and shapes these decorative Dahlia are loved by pollinating insects, in particular bees and butterflies. Dahlia are perfect for planting with other late flowering plants like Salvia and ornamental grasses.

  • These low maintenance, easy to grow Summer flowering plants are perfect for growing in pots or containers but can be planted up in borders and beds. They can be used as cut flowers allowing you to enjoy them in your home and garden. Dahlia tubers will provide a show all Summer and should be lifted, stored and replanted again the following year. Lifting them should take place before the first frosts, ideally mid Autumn. A light frost wont cause too much damage but leaving it too late in the season can damage the plant.

  • If you are not ready to plant bulbs now, then store them in a cool, dry, frost free, well ventilated location. A garage, shed, loft or cupboard are ideal. Open the paper bag to allow air to circulate round but leave the bulbs in their bags until ready to plant. Just make sure mice or other rodents cant get access to them. Keep an eye on your bulbs while in storage, if they are showing signs of going soft, it's best to get them planted before they deteriorate any further.

    Watering Water thoroughly after planting to settle the soil around the bulbs. During active growth, water in prolonged dry spells so the soil stays lightly moist but never waterlogged. Once the foliage naturally dies back, reduce watering and allow the bulbs to rest more dryly.

    Best Growing Conditions Plant in multi-purpose compost in sun or partial shade. Choose a position that does not stay waterlogged in winter, as good drainage helps bulbs return reliably. Allow the foliage to die back naturally after flowering so the bulb can store energy for the following season.

    Top tip

    Allow the foliage to die back naturally after flowering so the bulb can store energy for the following season. In colder parts of the UK, give it a sheltered position and provide winter protection during prolonged frost.
