Dahlia Glow Collection

Plant your dahlia in spring in deeply worked and enriched soil, for example with crushed horn or dehydrated blood. Place your tuber and crumble the soil well to fill it without any air pockets. Your dahlia should be covered with 6 cm (2in) of soil. At the end of planting, pour one litre of water. Water regularly for the first 6 weeks to aid in root development. Dahlia are sensitive to cold. They need to be overwintered. In November, the first frosts will blacken the foliage, which is the time to dig them up. Carefully remove the tubers, taking off as much soil as possible. Let the foliage dry out so that the tuber can replenish its reserves. When the foliage is dry, cut the stems to 10 cm (4in) from the tuber. Spread your bulbs in a box on a newspaper. Store in a frost-free, dry, cool, and dark place.
