Dahlia Fireworks Collection

Plant your dahlias in the springtime in deeply worked soil 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 liter of water. Water regularly during the first 6 weeks to aid in rooting. Dahlias are sensitive to cold, so they need to be overwintered. In November, the first frost will blacken the foliage, signaling it's time to dig them up. Carefully unearth the tubers, removing as much soil as possible. Let the foliage dry so the tuber can replenish its reserves. Once the foliage is dry, cut the stems to 10 cm (4in) from the tuber. Spread out your bulbs in a crate on newspaper. Store in a frost-free, dry, cool, and dark place.
