Special winter protection is only necessary for young plants. To do this, cover the ground around the shrub with bark mulch, dried leaves or fir branches.

As a summer bloomer, the hibiscus sprouts quite late, so that night frosts hardly damage the fresh shoots. Nevertheless, it can happen that individual shoots freeze to death in winter or late night frosts. You can simply remove them with regular pruning, the bush will sprout again in these places.

Hibiscus moscheutus

Another hardy species is the marsh marshmallow, bot. Hibiscus moscheutus. Unlike the common marshmallow, it is an herbaceous plant whose parts above ground die off in winter or are severely cut back before winter. Bark mulch, brushwood or dry leaves, with which you can cover the plant base, can also be used as protection against winter. In spring, the plant then sprouts from below.

Winter protection for the Chinese hibiscus in the bucket

The Chinese hibiscus or rose marshmallow is usually used as a tub or pot plant for the terrace. Hibiscis rosa sinensis, used from June to September

blooms in a sunny spot. The rose marshmallow is very sensitive and must therefore be brought into the house before the first night frosts appear.

The hibiscus can be pruned slightly before it is brought in, this encourages new growth in spring. The hibiscus needs a bright spot indoors. A room or stairwell with even temperatures between 12 and 15 ° C or a well-tempered winter garden is ideal. If the temperature falls below 10 ° C, the plant may die.

So that the hibiscus can keep its hibernation and bloom again vigorously next year, you should consider the following:

  • before retrieving for pest infestation, e.g. Aphids,

    check and fight if necessary

  • Remove faded and dead plant parts
  • water only moderately, the soil must not be too moist
  • The hibiscus does not need any fertilizer during hibernation
  • Regular ventilation prevents a possible infestation with spider mites

If the hibiscus begins to sprout in spring, you should water it again regularly. With a liquid fertilizer, the hibiscus can now be fertilized about every two weeks. Now is the right time to repot the plant in a larger container. From May the hibiscus can then be taken outside to a sunny and sheltered place.

Well meant and yet wrong

Even if it is meant well, many “hibernation measures” are exaggerated and only harm the plant. The ground around the marshmallow does not have to be covered with an additional film, this leads to rot and thus damages the plant. It is also not necessary to buy a fleece in the garden center, mulch (€ 213.00 at Amazon *) and brushwood are sufficient.

The hibiscus is still blooming and is therefore allowed to overwinter in the warm living room? Give your hibiscus a rest period in cooler rooms so that it can gather strength for the next budding.

Tips & Tricks

The hibiscus needs a bright room to overwinter. If it is too dark, it could lose all of its leaves. You should therefore only consider wintering in the basement if the basement has sufficient daylight.
