Dahlia Gallery Art Nouveau

Plant your dahlias during the beautiful days in soil that has been deeply worked and enriched, for example, with crushed horn or dehydrated blood. Place your tuber and crumble the soil well to fill in 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 during the first 6 weeks to help with rooting. Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frosts will blacken the foliage, which is the time to dig them up. Carefully unearth 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 box on newspaper. Store away from frost in a dry, cool, and dark place.
