Among the wide variety of plants for vertical gardening, the most advantageous option is clematis. Once planted, you can enjoy bright, carpet blooms for many years. Clematis is quite docile and not whimsical in care, but has one weakness – it can hardly endure frosts. In this article, you will learn how to prepare clematis for winter and make a safe shelter for them.
Top dressing and pruning in front of the shelter – needed
In autumn, like other wintering plants, clematis prepares for hibernation, but without human help it is much more difficult for them to do this. Without proper care and preparation in cold winters, they can die. Before sheltering, clematis will need:
- top dressing;
- treatment for diseases;
Mineral dressing for clematis is given by the end of the growing season, approximately from the end of September. They are strengthening in nature – phosphorus and potassium contribute to the ripening of shoots, help the plant prepare for winter, and accumulate nutrients.
Clematis are susceptible to certain soil fungi that can kill the plant. Autumn is the best time to cultivate plants and soil before pruning. Prepare a 3% Bordeaux liquid solution (or 2% Fundazole solution), sprinkle soil around the plant within a radius of 0.5 meters and spray the shoots. The root zone can be sprinkled with a mixture of sand and ash at the rate of 10: 1, this will help keep the root system intact.
Clematis are cut in groups.
- I – only the tops of the heads are cut off by 20 cm, since clematis of this group bloom on the shoots of the previous year. These vines must be preserved.
- II – pruning is carried out twice a season, at the beginning of summer after the first wave of flowering and in autumn, at the end of the second wave of flowering. In the first case, the old branches are completely removed, in the second, the faded shoots are cut off by a third.
- III is the easiest group to trim. In autumn, the shoots are cut off completely, leaving only small stumps, 20-30 cm high.
Regardless of the pruning group, diseased, dry and thickening shoots are removed every fall. We wrote in detail about the autumn pruning of clematis in this article.
Preparing clematis for shelter
A winter shelter should be reliable and protect the plant not only from frost, but also from wind and dampness. The best protection option is to use a dry, air method.
Shelter timing directly depends on the air temperature. Optimally, when the ground begins to freeze, and the thermometer is set at -5 degrees. But you need to prepare clematis for shelter earlier – water (no more than 1 time a week), spud the base of the bush, mulch the root circle by 10-15 cm with humus or ordinary garden soil.
Shelter clematis by groups
Clematis of the first and second groups of pruning go into the winter with shoots, which means that they will have the same shelter method.
On the ground, you need to build a substrate of brushwood or spruce branches. It is unsafe to use dry foliage, as it can serve as a wintering place for insect larvae and a breeding ground for pathogens. Lianas, twisted into arcs, are laid on a substrate and wrapped in any agrofiber. Cover the top again with spruce branches, dry grass or straw and fix everything with a piece of slate or roofing material (they will protect against moisture penetration). It is undesirable to use the film, it interferes with air circulation.
Covering clematis of the third group is much easier. The base of the bush must be mulched with 2-3 buckets of humus, covered with a wooden box upside down on top, covered with dry grass and wrapped in burlap.
Clematis hibernate well, but most often it is improper preparation that is the reason for the lack of flowering and poor development. Do not test them for endurance, take care and cover correctly so that the luxurious vine can only bring you pleasant surprises.
