Plant Edda® Clematis in well-draining soil with full sun to partial shade. Ensure the roots are shaded while the top receives sunlight. Water regularly, keeping the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced fertilizer. Provide a trellis or support for climbing. Prune lightly after the first flowering to encourage a second bloom, and perform a more thorough pruning in late winter or early spring to remove dead or weak stems. Protect from strong winds and ensure good air circulation to prevent disease.
