Care: Fertilize with Proven Winners® Continuous Release Plant Food in spring and midsummer. Requires well-draining soil. Prefers fertile soil that is neutral or a bit alkaline. Best in full sun or light shade, keep base and roots completely shaded. "Feet in the shade, head in the sun" is a saying you may have heard for successfully growing clematis, so plant it where the vine gets sunshine but the roots stay cool. You can accomplish this with mulch, or by shading the root zone with a nearby shrub or perennial. Benefits from staking, cages, or neighboring plants for support. Each spring, they can be trimmed down to 2-3' tall, but not required.
