Provide support for this vine. Plant it against a fence, wall or arbor. Place latticework or trellises by the plant. The plant twines its leaves around these supports and climbs up them.
Give the sweet autumn clematis at least one inch of water per week during dry weather.
Spread a thick layer of manure or compost mulch around the plant in the fall. This helps the soil to retain moisture as well as provide the plant with nutrients.
Every spring fertilize the vine using a general purpose fertilizer. Make sure to fertilize before the plant starts to flower.
This plant requires extensive pruning in order to control its growth. Never prune it during its first blooming season. After the first season, prune the vine extensively during the winter. Cut it down to 12 inches. Prune as needed during the summer.
