Hibiscus hibernate - so he survives the winter - 7 tips: hibiscus

Behind the fairytale fullness of a hibiscus hides an unexpectedly muscular constitution that allows uncomplicated hibernation. The feudal genus of mallow plants brings us both hardy and frost-sensitive species of marshmallow, which accompany us through the summer with their picturesque flowers. If the origin and exact plant species are known, you can easily make the right arrangements for the cold season. These 7 tips give practical examples of how the exotic flower miracle as a garden shrub, room plant and perennial stands the winter.

Provide young garden fish with cold protection

As summer-flowering shrubs enjoy the magnificent varieties of Hibiscus syriacus a high esteem. Thanks to a robust hardiness of up to - 20 degrees Celsius, every hibiscus of this botanical classification can be planted in the bed and over many years transform the garden into a summery flower fairy tale. As the frost resistance builds up successively, young plants are dependent on winter protection during a three to four year start-up phase. With these precautions you do it right:
  • In late autumn, pile a thick layer of autumn leaves on the root disk
  • Fix the foliage with brushwood or pine fronds
  • In wind-exposed situations, protect the young shoots with reed mats
  • Remove cold protection in the spring in good time before budding
If winter temperatures in the garden are generally not below - 20 degrees Celsius, these measures can be dispensed with after the construction phase. The winter-resistant varieties of the hibiscus can now offer as a separate force clashing frost.

Garden mélange in the bucket never without a winter coat

Its hardy winter hardiness of up to - 20 degrees Celsius is sufficient for a garden hibiscus only planted in the bed to the advantage. If you cultivate the floral piece of jewelry in the bucket, significant losses must be accepted in this regard. The root ball is surrounded by a smaller volume of soil and does not receive any actual protection from frost from the vessel walls. The largest load in the pot are permanent changes between frost and thawing, which tug on the cell walls in the plant tissue so that they can rupture. With a winter coat keep your hibiscus from the winter strain. That is how it goes:
  • Put the hibiscus in the bucket in front of the south wall of the house before the onset of winter
  • The plant vessel encase with several layers of jute, fleece or foil
  • Put a few wooden slats or polystyrene plates under the pot
  • Layer leaves, straw or bark mulch on the substrate
In the end, wrap the bucket with a mat of coconut, bast or reed, which projects beyond the edge by 10 to 15 cm. With this bulwark against severe frost you arm your hibiscus every year, because it can not rely on its winter hardiness in pot culture even in advanced age.

Sunny, nutrient-rich location optimizes winter hardiness


In order for the garden fish (Hibiscus syriacus) to be able to rely on its winter hardiness, it must not be weakened in its growth. The successful overwintering thus already begins with the location selection. In these locations the best prosperity is guaranteed:
  • Sunny to sunny location
  • Protected from wind and rain in front of a house wall or under a canopy
  • Nutrient-rich, loose and deep soil
  • Fresh to moist without waterlogging
In order for a hibiscus to establish itself well on the site by winter, spring is the ideal planting season. In order to provide the fleshy heart-root system with sufficient space for vital growth, please raise a spacious plant pit with twice the volume of the root ball.

Room hibiscus to cool in a cool and sunny place

The silky calyx and evergreen leaves of Hibiscus rosa-sinensis spread glamorous ambience in living rooms and conservatories. Since the Chinese Roseneibisch is located in tropical warm regions, it already shivers at temperatures of 10 degrees Celsius. The exotic sunbather can theoretically spend the whole year at his usual location behind glass. In the meantime, it is more advantageous for a lavish floral splendor and a long life to spend a cool winter so that the room hibiscus can regain fresh strength. So he survives the dark season without damage:
  • From October to February spend in a bright, slightly tempered room
  • Ideal temperatures range between 12 and 16 degrees Celsius
  • Shadow on the south window and in the conservatory in bright sunlight
The recommended winter roost also comes from the Roseneibisch, which decorates the sunny balcony from May to September with its furious flower show. At the latest when the nightly temperatures near the 10-degree mark, please allow the Sommerfrischler.

Never water the evergreen rosé in winter and do not fertilize it

If your room hibiscus enjoys a cool and light breather in winter, the care will be modified accordingly. Now pour the plant every 2 to 3 weeks with lime-free water so that the root ball does not dry out. In the period from October to February please do not give fertilizer.
If you favor wintering in warm living space, more watering is required due to higher evaporation. In addition, you continue to provide nutrients at extended intervals. Every 4 to 6 weeks, add low-lime liquid fertilizer to the irrigation water to balance the energy consumption during a warm winter.

Increased humidity keeps pests away

In winter quarters, spider mites, woolly mealybugs and lice lurk on the evergreen leaves to extract their sap. There is an increased risk of infestation under the influence of dry heating air. By increasing the humidity in the room with the following precautions, keep the hibiscus from sucking pests off your hibiscus. This is how it works:
  • Spray the tops and bottoms of the leaves every few days with soft water
  • In heated rooms, attach water-filled humidifiers to the radiators
  • Alternatively, set up a commercial humidifier in the immediate vicinity of the hibiscus
Please check the leaves every 2 days for a thorough check for pests. With a magnifying glass, the tiny pests are to be discovered in the early infestation stage and can be combated with home remedies, such as the soft soap solution.

Cut perennial hibiscus near the ground in autumn


Among hibiscus lovers, the cultivated forms of hibiscus x moscheutos, which thrive as herbaceous perennials, make a name for themselves. With imposing flowers of up to 30 cm in diameter and a stature height of 120 to 200 cm, the perennials are in no way inferior to the flowering shrubs in beauty. The winter hardiness of the garden hibiscus even surpass it significantly with up to - 30 degrees Celsius. So hibernate a perennial hibiscus in the bed:
  • In late autumn, cut off all shoots until just above the ground
  • Protect the root disc with a layer of leaves from excess moisture
  • In March clear the earth, so as not to hinder the shootout
  • Place the bucket on the wood and cover with bubble wrap
On time with the beginning of the warm season, a rapid sprouting from the wintered rootstock begins. An organic fertilizer brings growth at the end of the winter time in addition to momentum.
No plant friend has to do without the fierce flower rush of a hibiscus, because he fears an elaborate and complicated hibernation. He survives the winter in the garden and as a houseplant without injuries, if these 7 tips are heeded. At a young age and in a bucket, the garden marshmallow is prepared with little precautions against frost, because it can build on a natural winter hardiness of up to - 20 degrees Celsius.
