Dahlias are a beautiful addition to your garden and they are one of the UK’s favourite plants.
Originating from Mexico and Central America, the exquisite Dahlia is named after the 18th century Swedish botanist Anders Dahl, who originally intended to grow these luxurious flowering plants as a food source!
Today they are favoured for their bounteous blooms rather than for their flavour. The sheer range of Dahlia varieties provides our summer borders and pots with such a wealth of textures, colours, heights and sizes that the display and arrangement possibilities are endless.
Caring for and growing Dahlia tubers:
Whichever Dahlia variety you choose to have in your garden this summer, satisfaction is guaranteed. Dahlias are easy to grow from tubers and represent excellent value for money. The tubers, when properly looked after, can be re-used year on year. We have put together a short step-by-step guide to planting and caring for Dahlia tubers to get you started:
• On safe arrival of your chosen Dahlia tubers in the post, soak overnight in a bucket of water. This hydrates and softens the tuber, ready for planting once all signs of frost has passed- around May to early June.
• If planting the tubers in a pot, we recommend placing Leca (Hydroleca) at the bottom for drainage. Fill with compost and place the tuber so it’s held firmly at 10-15cm depth, tip facing upwards and peeping out, just above the soil-line. Insert the cane (if required) for support carefully, so as not to damage or pierce the tuber.
• After potting, place in your chosen sunny location and water well. Keep the pot moist but not waterlogged as the tubers will rot. Add liquid feed during growing season and be sure to offer protection from slugs who particularly enjoy Dahlias.
• Once flowering is finished, carefully lift the tubers before the late autumn frosts set in. Remove soil from the tuber and place in the sun until the skin hardens before storing in a dry and well-ventilated location. You could pack tubers in a pot with dry compost and place in a greenhouse or dry shed for safekeeping.
