Dahlia Red Devil

Plant your dahlias in the springtime in deeply worked soil enriched, for example, with bonemeal. Place your tuber and crumble the soil well to fill without any air pockets. Your dahlia should be covered with 6 cm (2in) of soil. At the end of planting, add one litre of water. Water regularly during the first 6 weeks to aid in root development. Dahlias are sensitive to cold. They need to be overwintered. In November, the first frost 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 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 newspaper. Store in a frost-free, dry, cool, and dark location.
