Identify my clematis

Clematis montana has white flowers of 10 cm with four petals and anthers of cream color. Its leaves are composed of 3 lanceolate leaflets, and it blooms in June.

Plant my clematis

The clematis appreciates to have its head in the sun and its foot in the shade, facing South or West. Plant in late autumn or winter, in unfrozen soil, during the dormancy of the plant. Plant in a hole at least twice as big as the root ball. Soak the roots in water before planting, it should improve the chances of recovery. Keep a hollow around the base, it will serve as a water reserve during the first months. Tamp the soil well around the roots (do not hesitate to use all your bodyweight). Water until the hollow is full, and the level decreases very slowly (at least two watering cans). Clematis prefers to have shade at their base, shelter it with a flat tile Also cover the base with a small mound of soil, which will promote the emission of shoots from the stump. Provide the clematis with a small support pole to bring it to its final support. Clematis easily reaches 5 m despite a regular trimming, so use a sturdy support.

Water my clematis

Water twice a week if you have planted early in season during the first month, and possibly all summer in case of drought. Some varieties bloom very early, in this case they do not need watering during flowering - but as early as May, watering can be useful. Water copiously but infrequently to encourage the root system to seek water deep underground. It's therefore suitable to water until the planting basin is full and only empties slowly.

Trellise my clematis

If the new stems aren't twisting and attaching to the support by themselves or if the plant "collapses", rehang them.

Mulch my clematis

Mulch the clematis to limit the challenge of "weeds", and evaporation. Spraying a layer of 5-10 cm mulch of bark or wood is recommended.

Fertilize my clematis

Mulch you clematis with compost or well-decomposed manure in February or March.

Prune my clematis

Cut your clematis montana after flowering, either in the summer or in the fall - it will not blame you! You must know that the more you cut the Clematis montana, the more it flowers! You should shorten the stems without pruning too harshly. Cut short only dead branches and fragile stems.
