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. |
Cooking Notes | All dahlia flowers are edible. I use the petals scattered over salad and to decorate a range of puddings. |

Lovely dahlia
Reviewed 22nd September 2018 by Penny Calthrop Bought just one of these and should have got more-lovely upright not too tall dahlia that I planted at the front of a border. Beautiful to look at from my kitchen window! Unfortunately the recent gales blew some petals off before their time....only thing I would say is that it produced few flowers. |
