Care Guide

Watering

Water deeply and regularly, especially during dry spells. Clematis prefers 'feet in the shade, head in the sun', so keep the roots cool and moist.

Sunlight

Ensure the foliage gets at least 6 hours of sun daily, while shading the base with mulch or companion plants.

Soil and Fertilizer

Plant in rich, well-draining, neutral to slightly alkaline soil. Feed in early spring with a balanced, slow-release fertilizer.

Pruning

Prune according to your clematis variety's specific group (Group 1, 2, or 3) to ensure optimal blooming.

Propagation Methods

Cutting

Take stem cuttings in late spring or early summer from healthy shoots, dip in rooting hormone, and place in a propagating mix.

Layering

Bend a low-growing stem to the ground in spring, wound it slightly, bury a section in soil, and detach once rooted.
