Dahlia Gallery Leonardo

Plant your dahlias during the warm 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 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 growth. Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost will blacken the foliage, signaling the time to dig them up. Carefully remove the tubers, taking off as much soil as possible. Allow the foliage to dry so that the tuber can replenish its reserves. Once 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 place.
