The hibiscus has many different grades. Some can quite grow in soil and even perfectly transfer winters in the Russian mid-latitudes. However is also such which demand special conditions in cold time of the year.
What types of hibiscuses need the shelter for the winter?
It is very important to know that not all hibiscuses need to be covered for the winter. "it is better to perebdet the rule, than to overlook" in this case does not work. If to overdo with care – it is also possible to ruin plant. And therefore the owner of this strange plant first of all needs to understand it has got what grade and respectively to understand how to look after him in the winter including. For example, hybrid (grassy) hibiscuses are rather resistant to frosts therefore in the conditions of quite mild climate (such as in the center of Eurasia) they do not need to be covered. The Syrian grades should be warmed for the winter. Especially it concerns terry hibiscuses. One more feature of hibiscus: together with its sizes also the frost resistance grows.
Specialists in cultivation of hibiscuses just recommend hybrid plants to cut off in the fall up to the height of stalk about 10 cm, to pritrusit the earth or to privalit leaves. However it is necessary to remember that too big use of foliage can be the reason of rotting of plant as during the periods of warming rerotten layer will be formed there.
Certainly, if for the winter predict temperature to - 30 wasps below, all plants need the shelter. And very gentle hibiscuses need to be put simply for this time in pot or other capacity and to bring to the room.
Basic methods of concealment of hibiscus
It is the best of all to begin to prepare hibiscuses from the middle of November. Key indicator is air temperature – it has to reach 5 OS of frost, but not fall below yet - 10 wasps. To save plants from frosts, it is possible to cover them with the fitted frameworks. Fabric has to be nonwoven (for example, agrotex, spunbond, lutrasit). However at very low temperatures you should not put them not to allow perishing. Branches of coniferous plants, so-called fir twigs are considered the most suitable for concealment of hibiscus. It is good the fact that it holds snow on itself(himself). Thus, plants are well protected from frosts, but also do not overheat. Build of branches small shalashik. The fir twigs are connected among themselves and wound with rough fabric from rigid fibers. Covering hibiscus with branches of evergreen trees, it is necessary to think of that there rodents did not get in advance. For this purpose it is possible on area perimeter where flowers grow, to place devices for catching of mice. Or to impregnate forage for rodents with special poison and to put it under the covering design.
