Plant Sarah Elizabeth® Clematis in well-drained soil with full sun to partial shade. Ensure the roots are shaded and cool. Water regularly, especially during dry spells, but avoid waterlogging. Support the plant with a trellis or fence. Prune in late winter or early spring, cutting back to strong buds about 12 inches above the ground. Fertilize in spring with a balanced fertilizer. Protect from strong winds and ensure good air circulation to prevent disease.
