How to cover hibiscus?

If in your area there is no frost above -15 ° C, then it is enough to build a frame around the bushes and cover it with agrotex, lutrasil or spunbond. A more severe winter requires a different shelter; spruce branches are perfect for these purposes. It allows air to pass through and traps snow, thereby creating comfortable conditions for hibiscus wintering.
The bases of small bushes can be wrapped in burlap, and the branches can be covered with a hut made of spruce paws. It is advisable to bent the weaving varieties to the ground, wrap them in burlap or non-woven material and cover them on top with the same spruce branches.
To prevent the plants from spilling out in the spring, remove the shelter with the onset of warm days. If perennials do not wake up for a long time, do not despair, this is normal. For example, the Syrian varieties may start developing in May or even June.
