Sowing, Seeds, Planting | 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 |
