Garteneibisch / hibiscus does not bloom - causes + special care: causes

A flowering hibiscus is a true adornment - whether it's planted in the field or graced with a bucket. Therefore, it is particularly annoying if the well-known as garden lemon plant does not bloom. However, as numerous as the causes may be, they can usually be eliminated quickly and the flowering strength can be strengthened again.


Sunny or at least partially shady should be the location for the garden marshmallow. If it is too dark, the hibiscus loses its flowering power. Even if roots have formed, they are often thrown off in wrong site conditions before they can open.
In addition, care must be taken very carefully to drafts and temperature fluctuations. The location may be airy. However, the garden fish reacts very sensitively to cold drafts. It is therefore ideal to plant or place it in a wind-protected position. The south side near walls is optimal. On the balcony or the terrace, the plant should rather stand on the wall of the house than on the parapet.
Tips: In the case of a hibiscus, which is cultivated indoors, attention must also be paid to drafts. On leaky windows and doors or even in the middle of the train in the middle of the train, the garden fish should not stand. In addition, he should change the location as rarely as possible, because he tolerates bad.


Also, the substrate may be a reason that the hibiscus does not bloom. It should meet the following requirements:
  • Potted or potting soil
  • Weakly acid or neutral
  • Neither clay nor clay
  • Not tending to compaction
  • Moderate to high nutrient content

High quality and nutrient-rich potting soil is recommended. For older substrates, adding mature compost and, if necessary, some sand can provide the optimum conditions. In fact, a mixture of mature compost and some sand can also be used directly.

to water

The water content of the soil and the moisture play crucial roles for the flowering joy of the garden marshmallow. If there is a constant change in humidity, this can already bother the sensitive bud. Even worse are the effects of wrong casting. The following factors should be considered:
  • Do not use cold water, it should be stale and at least correspond to the outside or room temperature
  • Casting takes place only when the uppermost layer of the substrate has dried
  • The watering should be done regularly to avoid extreme fluctuations
  • Waterlogging is urgently to be avoided so that no root rot occurs


A sufficient supply of nutrients is crucial for the garden marshmallow to produce buds and flowers. If they are absent, the plant inevitably weakens and has no strength left for the formation of leaves and flowers.
The hibiscus should therefore be taken care of. Advisable are among others:
  • liquid fertilizer
  • pond water
  • Vegetable or vegetable seep
  • compost
  • Patentkali
Liquid fertilizer, pond water, and plant sud and manure may be administered during growth and flowering every two weeks. Compost should only be spread once a month on the ground and easily incorporated into its surface. Patent potassium is administered only once a year, between August and September.
Tip: A clear sign of a nutrient deficiency is an overall poor growth but also withered or discolored leaves may indicate.


Hibiscus syriacus - Straucheibisch - garden hibiscus

The garden marshmallow can be wonderfully cut in shape - be it as a high stem or shrub. However, buds can also "fall victim" to the measure. The best time is therefore in the late winter, so about in January or February. The blend can also be omitted, but it favors the long term, the strong formation of buds and flowers. If the garden marshmallow is no longer blooming, then a rejuvenating blending could help.
When blending the hibiscus, the following points should be noted:
  • Use a clean, ideally disinfected cutting tool
  • Remove all dead and weak shoots as close as possible to the main stem or the next larger branch
  • Adjust the crown if necessary
  • About one quarter of the length to lose weight
In a rejuvenation cut, all instincts are cut more radically. There is only a length of 30 to 60 centimeters per shoot. This procedure is only necessary if the garden marshmallow has not been blended over several years and the flowering power subsides.


A grown garden marshmallow is good frost hardy and requires no further precautions in a sheltered location to survive the winter unscathed. In young plants and the culture in the bucket, however, it behaves a little differently. A hibiscus in the tub should be wintered indoors and frost-free.It is only necessary to ensure that the temperature of the winter quarters is not more than 10° C and that the substrate does not dry out completely.
If the garden marshmallow has just been planted or if it is a young plant, the hibiscus should be well protected in the field by a mulch layer. Wrapping with garden fleece can be useful in windy or drafty locations, to protect the plant's forces and thus increase the flowering power.

Care mistakes, diseases and pests

The garden marshmallow is robust in itself, but can get sick due to care mistakes, root rot or chlorosis. Root rot caused by waterlogging, so for example by excessive watering or a poor drainage. These risk factors can be avoided by introducing drainage into the planting hole or bucket and pouring it appropriately. If the hibiscus is already ill, it must be dug up, dead root ends removed and the substrate changed.
Chlorosis is a deficiency syndrome characterized by discolored leaves and absent flowers. Fertilization is both preventative and balancing.

Hibiscus rosa sinensis

Spider mites and aphids are most common on the pest side. Both species can weaken the garden marshmallow and thus cause a loss of the flowers. Against aphids it helps to spray the plant daily and thoroughly with nettle sud. In spider mites it helps to increase the humidity around the leaves. The hibiscus is showered and wrapped in foil. It would be ideal if it can be attached airtight. After two to four days, the film is removed and the hibiscus showered again. The measure is repeated until no more spider mites and weaving are discernible. In between, however, the leaves and the bark should be allowed to dry, so that it does not mold.
Tip: If the hibiscus does not flower, it should be examined for signs of disease and pests. Often, these can almost unnoticed for a long time to ensure weakening and loss of buds.
In the case of declining or lacking flowering power of the garden marshes it often already helps to check the conditions at the location and the care and adjust them if necessary. Anyone who learns in advance about the claims of the plant and the most important requirements, can even prevent the absence of flowering hibiscus.
