3 hiding method onto the winter
Without shelter roses, especially hybrid tea, do not spend the winter. It is best to cover the roses in dry weather. Universal way to cover roses do not exist. Each gardener must choose a method depending on the kinds of roses, and the area where they are grown.
How to prepare roses to the shelter
Begin to prepare roses to the shelter since mid-October. It is necessary to conduct sanitary pruning of shoots (old, broken branches), and then cut off all the lower leaves from the stems using secateurs.
Falling leaves (usually they can be infection) under the bushes need to remove a rake and burn.
Before shelter desirable to treat the copper sulfate rose bushes, Bordeaux liquid or mixture oksihom.
It is important not to overfeed plants, otherwise it will start to fatten, to develop green shoots in the autumn, which rarely hibernate. Besides overfed roses often suffer.
Starting from mid-July these crops can not be fed nitrogen fertilizer, can be used only phosphorus-potassium fertilization. The last making fertilizer in September.
Before the shelter you can wake up around the bushes ashes of roses. In the middle zone rose harbor until early November (depending on the weather, perhaps earlier).
The first way to the shelter. Spruce branches and okuchka
With this method applies spruce branches, and produce okuchku. Preparing the soil dry advance, which is stored in a safe place, a refuge. Then fall asleep bush land, as if okuchivaya plant. It is possible to use peat or compost, or a mixture of these materials with sand.
The shrub is enough to pour buckets of 1-3, depending on the age of the plant.
After hilling bush covered with spruce branches. Expose branches as shalashika and tied top. The main function of lapnika - a snow retention.
The first way to cover roses in the winter is the easiest, but not the most reliable. Upon the occurrence of damping-off of thaw can occur, which this culture is afraid too. Therefore, this option is suitable for areas where thaw is unlikely in the winter.
The second way cover. Using film
Roses also backfilled soil as in the first embodiment, but instead make lapnika frame top of wire or wooden chopsticks, which is covered film.
But in case of thawing damping-off may also occur due to condensation under the film material. Therefore, at positive temperatures need to slightly open ends of the cover.
Roses are cut by the frame height. If the shoots bend down to the ground without any problems, you can do without pruning, because duck shrubs tolerate cold better than the cut. Fix them to the ground, sheltered spruce branches, using slingshots from twigs, arcs of wire.
The third way. Application spunbond (lutrasila, AGROTEKS)
Nestle rose spunbond density of 60 c. 2 smooth surface top layer (rainfall will roll down the agrovoloknom, only a small fraction of them could get inside). This material is breathable in contrast to the film.
The second and the third method is well suited to cover hybrid tea roses and floribunda.
