Dahlia Frost Nip

Plant your dahlias during the warm days in a deeply worked soil enriched, 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 the planting, pour a liter of water. Water regularly for the first 6 weeks to help with rooting. 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. Remove 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 10 cm (4in) from the tuber. Spread your bulbs in a crate on newspaper. Store away from frost in a dry, cool, and dark place.
