In early spring, do not rush to remove protection from rose bushes covered for the winter. But the difficulty is that even a long stay of the plant under protective material is fraught with consequences.
Here are some tips on how to solve this problem without harming the shrub.
Even if it is an air-dry shelter, this does not mean that the bush can sit under it for half of March.
Such frame structures provide good protection from wind and bright sun, but not from frost. In spring, their main drawback is the lack of air circulation, which is fraught with the development of fungal diseases and plant damping off, which happens more often than freezing.
Where to start
They start with the planned ventilation of the shelter, when the protective material is raised on both sides. At this time, the air temperature should be within 5 degrees Celsius during the day.
It is important to inspect the bush at this time. Even if white mold appears, you can leave the plant in the sun for 20-30 minutes, and it will disappear.
After this, the shelter is returned to its place.
It is important to prevent shoots from rotting, which often happens in spring. To do this, the material is raised from the north side so that the sun's rays do not fall on the bush.
In March, it is too early to remove the protection, and until the soil has completely thawed, the roses are kept under cover.
At this time, you can remove the layer of humus or peat that was used to cover the roses for the winter.
Airing continues until mid-April or later – until the temperature rises above +15 degrees Celsius and the threat of night frosts disappears. When it gets warmer, roses can be placed under a spunbond frame – it lets in air and light, but protects against burns and cold wind.
