Roses and frosts.
Roses - heat-loving plants that require careful shelter from the cold. Growers develop their own methodology for hiding roses with the features of the site and local climate.
Many ways to cover roses can be divided into two groups:
- Hilling rose bushes, followed by warming of different materials (spruce branches, leaves, peat, sawdust, etc.).
- Hilling rose bushes and then air-dry the carcass shelter.
By the winter roses are beginning to prepare in advance, creating the conditions for a good aging shoots in the second half of the summer stop fertilizing with nitrogen fertilizers, reduce watering and hoeing. Also prepare all necessary to cover roses ground sand for insulating materials and store them on demand in a dry place.
The first light frosts do not bring harm roses, promoting hardening shoots. Before the onset of significant frost to the base of a rose bush spiked sand and then spud bushes Stored ground to a height of 10 cm (dwarf roses) to 40 cm (tall rose). This is important, since even a slight long frost (-3 degrees) is already able to damage the tissues of the shoots.
After some time, when you install frost (roses stand short frosts down to -15 degrees) and topsoil promÑ‘rznet a few inches, held the final cover roses. To protect the roses from diseases before shelter shrubs can be sanitized trÑ‘hprotsentnym Vitriol.
Shrub Roses shelter before cut (leaving stems about 30 cm long) were removed nevyzrevshie shoots, leaves and burn them. Shrubs draped spruce branches and poured on top of a thick layer of insulated material. Using twigs to cover roses especially recommended: it has antibacterial properties and repels mice. Also practiced over the insulation lay branches and bushes around the boards to arrange for snow retention.
Stems and pletistyh polupletistyh, standard roses to cover neatly ties it all together with synthetic cord (cord of moisture absorbent material can be a source of infection) and bends to the ground before the frost-resistant, yet shoots retain elasticity (otherwise when handling may crack the crust).
For shelter and pletistyh polupletistyh roses their stems removed from the support; if more than 10-12 stems, then cut shoots over three years, as well as the weakest unprospective (if you shoot less, then leave everything until the spring). Shoots linked and placed on okuchennoe and nestled lapnikom base bush or bends to one side and fixed in an inclined position connected by an angle and stuck in the ground with wooden stakes. Top shoots are covered with spruce branches and covered with leaves. In regions with relatively mild winters and climbing roses are covered with spruce branches polupletistye directly on the support, fixing the spruce branches on the stems and support with a cord.
Stam roses without leaves untie the reference peg, break ground on the other side, which will be tilted shtamb slightly tilted it gently bends to the ground, fixing stakes, straps, and spears; trunk shtambovoy roses need to impose spruce branches and secure the cord and the base of the bush and the crown covered with soil (especially carefully locked place shots). Top can sketch spruce branches and leaves everything to fall asleep.
Another way to cover standard roses: roses from the trunk in the direction of inclination dig a trench depth of about 20 cm, and for the crown - a deepening of the appropriate size, which rose stack stam all entirely, falling asleep on top of her land and spruce branches; top set orientation pegs. In regions with relatively mild winters stam roses are not tilted to the ground and draped their trunks and crowns of spruce branches and fix the cord.
Air-dry shelter, when over okuchennymi previously bushes in determining frost and freezing of the soil a few inches set frames (wood, metal), which pull the covering material (also used mats, paper, etc..) And then placed on top of a polyethylene film ( on which you can then sketch spruce branches and leaves) gives the best results wintering roses with severe winter.
For separate rose bushes can be made scaffolds roofing material in the form of two different sizes of cones with an air gap between them, fixing them with stakes and pushing from below the ground by metal straps. When the air-dry method is needed shelter frame such a height that between circumcised or weighed down with roses and top cover had a free air space of at least 15 cm.
Air-dry shelter provides a favorable climate for the winter and protect rosebushes not only from low temperatures, but also from the high humidity, because the greatest losses roses come from waterlogging and decay shoots. Used to cover roses frames must be strong enough to withstand the snow cover; soundly constructed and robust frames can be reused from year to year.
However, experienced growers warn in damp areas under the air shelter collects condensate, which leads to damping-off of roses; in this case it is better to use the first way to shelter high hilling bush land and then a thick layer of insulation shelter materials.
In some years, in the spring and fall are frequent thaws (causing an increase in temperature and humidity under the frame, causing the kidneys start to grow ahead of time and shoots lose frost), and winter passes without severe frosts, rose in the first method the shelter saved better than second.
