Planting Conditions

Plant n a sunny, but sheltered spot and rich, fertile soil. It's not too fussy, provided the soil is moist, but well-drained. Add some sand or grit when planting if your soil does not drain that well. You can tell if your soil is healthy if there is plenty of underground activity such as plant growth, earthworms and fungi. Alternatively, purchase a soil testing kit which will let you know what type you have.

Watering & Feeding

Watering correctly is important to keep your Dahlia healthy. Check if it needs watering by handling the soil, if the soil feels moist but not wet, it does not need watering. If the soil feels soggy or wet, it needs some time to dry out. If the soil feels dry, then it’s time to water. Water evenly at the base as watering the flowers and leaves can cause rotting. If planted in a container it will be saturated when moisture begins to seep from the drainage holes, while ground watering should stop when the ground begins absorbing slower than you're watering.

General Care

As the flowers start to fade, cut back the stems to a leaf joint as this will encourage the plant to produce new buds. At the end of the season you can leave the Dahlia tuber in the ground if you live in a warmer part of the UK and your soil is very free draining. If overwintering outdoors you will also need to cover with at least 6 inches of mulch like bark chippings etc… If you want to give your Dahlia the best chance of coming back the next season it's best to dig it up before the winter, do this when the foliage has started to die down. Dig around the clump and the lift the tuber with a fork, take great care not to damage it with the fork. Shake off the excess soil and using secateurs, remove both the stems and leaves. Rinse the tuber with water, then hang it up to dry. Once it has dried wrap the tuber in newspaper and store it in a dark, dry place for winter - this needs to somewhere cool, but frost free. The following spring plant the tuber in the ground once the risk of frost has passed.
