clematis

Clematis durandii should be watered regularly throughout the growing season. Water the plant deeply at least once a week, providing 1 to 2 inches of water. To ensure an adequate amount of water is reaching the roots, aim to saturate the soil about 8-10 inches deep. Be sure to avoid waterlogging, though, as this can cause excessive stem and root rot. During extreme heat waves, Clematis durandii may require additional water for optimal health. Water the plant more frequently if dry conditions persist. In the winter months, when the plant is dormant, watering can be reduced to once every 2 weeks.

Clematis durandii, commonly known as stonemason's clematis, needs 6-7 hours of direct sunlight in order to grow and flourish. To be in optimum health, it should get at least 4 hours of sunlight each day, with 2-3 hours of full direct sun and the remaining day in the morning and afternoon or in filtered light. However, if placed in a very sunny spot, Clematis durandii should be acclimated to the light by providing partial shade for a few days, as too much direct sunlight can harm it. This species prefers full sun to partial shade, with some afternoon shade in areas with intense summer sun. Temperatures should not go below 45 degrees Fahrenheit for it to grow properly, so it should be sheltered during colder seasons.

Hardiness zone 5–9.

Clematis (Clematis durandii) should be pruned twice a year for optimal growth and health. During the first pruning in early spring, remove any dead, damaged, or weak stems. Cut back the other stems to a length of 18-24 inches or to the desired shape. If desired, leave 4-6 buds on the end of each stem. During the second pruning in late summer, reduce the length of each stem by a third or to the desired shape. This pruning encourages more vigorous flowering in the next season. If desired, leave 3-4 buds on the end of each stem.
