This is a description for very-early-spring-flowering clematis cultivars - "group 1" - that sometimes bloom from January!
Common name : Early clematis
Scientific name : Clematis spp. 1
Family : Ranunculaceae
Category : Climbing plants
Type of plant : Perennial
Cultivars of this group need to be pruned right after flowering. Clematis are great climbers, with sometimes deciduous foliage, which means that in the winter their leaves and their stems dry. They get into dormancy, and when spring comes, they produce new stems at a breathtaking rate, and then leaves and flowers, in search of anything to hang on to!
This climber can reach 14 meters in height in good conditions.
Clematis is a genus of the family Ranunculaceae, which includes about 30 species of woody herbaceous perennials and climbers, semi-woody, evergreen or deciduous plants.
They are cultivated for their abundant and very decorative flowering! There are more than 40 cultivars, and because of the diversity of species, the appearance of clematis varies considerably.
Groww distinguishes 3 types of clematis, mainly according to the type of pruning to be made: this description concerns group 1 clematis, that is, those that are pruned, if necessary, just after flowering - which takes place very early for certain varieties, sometimes from January!
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.
Prune my clematis
Prune - if you feel invaded - after flowering. Remove dead or damaged stems, and shorten others if necessary to promote branching.
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.
