Clematis

Plant Information

Culture: Clematis can be planted anytime the ground is workable. Because they are such long-lived plants, it is essential to site and plant them appropriately. Clematis require at least 5-6 hours of full sun, or all day filtered sun. They prefer rich, loose, well-drained soil. A cool root zone is essential, so use rocks, mulch or groundcover to provide shade. To support their climbing habits, always provide a shrub, tree or trellis for climbing. Pruning: Where flowers form determines how and when Clematis should be pruned. Those that bloom only on growth produced the previous year should be lightly cut back as soon as they finish blooming in May or June. Clematis that flowers in spring on last year's growth, and again in fall on this year's growth, should be lightly pruned in late February or March. Clematis that bloom in early summer to fall on the current year's growth tend to become quite leggy over time, with flowers occurring progressively higher, leaving much of the vine naked. These vines are well suited to being trained up into a tree where their growth habit works well. Another option is to aggressively cut back summer-blooming forms in late February or March to two strong sets of buds on each stem as close to the ground as possible. This will ensure a compact vine with flowers at eye level.
