Common Name | Dahlia |
Border Position | Cutting Garden |
Bulb Size | I |
Soil Type | Broad Tolerance |
Scent | Unscented |
Site | Full Sun |
Moisture | Moist but Well-drained |
Height | 1.2m (4ft) |
Spacing | Plant just under the soil surface, 75cm (30in) apart. |
Sowing, Seeds, Planting | Plant just under the soil surface after the last frosts. Alternativley pot them up undercover March or early April in a generous pot (at least 2 litre) filled with multi-purpose potting compost. Place them in a light, frost-free place and keep the compost moist. Pinch out their growing tips when they have reached about 8" tall. They will have formed bushy plants by the time the frosts have ended and will be in flower by the beginning of July. If you don’t have anywhere to grow the potted tubers, you can put them straight into the ground when the frosts are nearly over, mulching them or protecting with a cloche or protective horticultural fleece if the foliage appears before the frosts are over, but this will delay flowering. |
Care Tips | Support with a stout stick, tie in every couple of weeks. In the south you can mulch deeply and overwinter them in the ground, alternatively, lift and overwinter your dahlias frost free undercover. |
Flowering | July - November |
Vase Life | Only pick dahlias in full flower. Recut the hollow stem ends under water to avoid airlocks. |
Harvesting | Flower production 5 months |
Cooking Notes | All dahlia flowers are edible. I use the petals scattered over salad and to decorate a range of puddings. |

Reviewed 11th August 2019 by Andrew sale item so didn't expect too much but only 2 of the 5 germinated, but they are great |
Reviewed 5th August 2019 by Susan I’ve given the Rubens Dahlia Collection 3 stars as only 3 out of the 5 tubers germinated. I started them off in pots and followed all instructions. I have planted my 3 Dahlias into the ground now and they are doing really well and seem very healthy. I've a few buds so will hopefully see some flowers very soon |
Reviewed 5th August 2019 by Anna Again not all have come up, but better than WM. |
Reviewed 5th August 2019 by Lara Planted all five in a new bed with mixed success. One (Café au Lait?) just never made an appearance. Two had their buds decimated by earwigs, one has flowered beautifully (Linda's Baby) and another is on its way to blooming. Bit disappointing as a nice collection. |
Reviewed 1st August 2019 by Janet All the dahlias are growing and flowering well. Very pleased |
Reviewed 31st July 2019 by Erica The dahlias are fabulous. Strong healthy plants with lots of flowers. I have tied them in twice now. We hammered in big stakes and neighbours. Must have thought we were crazy. Most of them are up to the top of the stakes now. Except the singles |
Reviewed 31st July 2019 by Penelope Good quality tubers and now lovely plants |
Reviewed 31st July 2019 by Tracy My delivery came when expected and was securely, but more importantly not over packaged. I am absolutely delighted with my dahlia. Each plant is strong, healthy and thriving. We’ve an absolute abundance of flowers. We are keen gardeners and have decided to purchase the bulk of our next season’s purchases from Sarah Raven. I’m so delighted that I’ve chosen Christmas gift ideas from the new Sarah Raven catologue, which is an absolute pleasure to use. |
Reviewed 31st July 2019 by Lee Look better in the photos and further discounts in the year after purchasing - |
Reviewed 31st July 2019 by Ildiko The tubers were on the small side, but viable, and once growth started there was no stopping them. Sarah's collections are really well thought out and put together. I love them. It is the end of July now and all five dahlias have been flowering beautifully since mid July. |
Reviewed 31st July 2019 by Lin All grew. I had forgotten that I had bought two lots the previous year, all of which came up again, despite being left all winter. Bonus! |
