clematis

Clematis triternata 'Rubromarginata' should be watered on a regular basis, at least once every 4-5 days. During the midsummer, watering should be increased to twice a week in order to keep the soil moist. The soil around the plant should never be allowed to dry out completely, as this can cause the plants to suffer from die-back. In addition, the plant should be watered at its base, as wetting the foliage can cause mildewing. During hot weather, it may help to apply organic mulch, such as wood chips, around the root area to help retain moisture. When watering, use tepid water and do not fertilizer it until it is established.

Clematis triternata 'Rubromarginata' does best in full sunlight for about 6 to 8 hours each day. Although it can tolerate some dappled sunlight or partial shade, it will not flower as well in low light conditions. For optimal flowering, it needs to receive direct and bright sunlight during the early morning and mid-day. During the hottest parts of the day, the plant should receive some shade to prevent sunburn and wilting.

Hardiness zone 5–8.

Clematis triternata 'Rubromarginata' should be pruned twice a year for optimal growth. Pruning should occur early in the spring and late in the summer. Prune the stems in the spring to about 6 to 12 inches. Remove all dead or weak wood and prune back any side shoots that may have occurred. In the late summer, prune any additional shoots that have grown. Take care to remove any dead or weak wood, and also cut back any shoots that may impede the plant’s desired growth pattern. After pruning, use some kind of fertilizer to promote optimal growth.
