Growing Tips & Maintenance

Clematis grow best in a rich, moist to average, well-drained soil, in full sun. Protection from intense afternoon sun is beneficial. Large flowering bi-colours, reds and blues, may fade quickly if planted in direct sun. Roots need a cool environment to thrive; it is recommended to plant a ground cover or shallow-rooted perennial to shade the roots; mulching is suggested. Plant the crown 3-5 cm below the soil's surface. Clematis are slow to establish and initially need to be tied to a trellis or fence to begin climbing.

Note

Additional Notes

Clematis are grouped into three, different categories for pruning and maintenance:Group 3: Late Flowering - Flowers form on the terminal, 60-90 cm of the current season's growth. Some bloom as early as midsummer and continue into the fall. In early spring, prune each stem, leaving the lowest 2-3 buds. The new growth can be tipped back when it reaches about 30 cm, to induce better branching and flowering.
