Choosing the right location
As an exotic species, the hibiscus loves warm and bright locations. Are ideal
- sunny pitches
- little draft
- south-facing house walls
Unsuitable substrate
In addition to a sunny location, the soil conditions must also be right. The plant cannot tolerate drought. In order to develop its handsome flower, it needs well-drained soil. During massive downpours, waterlogging must not occur. On the other hand, light moisture and a slightly acidic to neutral pH value are ideal. Likewise, the soil should contain sufficient nutrients
Wrong fertilization
Furthermore, a fertilizer enriches the soil. This should be done once a year. Suitable means are
- Compost
- stale pond water
- Jauche
- organic complete fertilizer
- Patentkali
- Epsom salt for sufficient magnesium
- Liquid fertilizer
Pouring behavior
The hibiscus is very sensitive to cold water and to significant changes in humidity. Therefore, only stale water should be used for watering, which corresponds approximately to the outside temperature. The water is only given again when the top layer of the substrate has dried on. Otherwise waterlogging will form, which will lead to root rot. A clear sign of insufficient watering, on the other hand, is the yellowing of the leaves before they completely fall off.
Frost
Once a garden hibiscus has got used to the climatic conditions, it can withstand harsh winters without difficulty. However, young plants or newly planted plants react very sensitively to freezing temperatures. They are best overwintered under a fleece or with a thick layer of mulch.
Damaged roots
Extreme caution is required when moving a garden hibiscus. Even the smallest injuries to the roots make it difficult to re-form at the new location. If individual parts should nevertheless be separated while excavating, only patience helps and hope that the plant will regenerate on its own.
cut
Older specimens in particular no longer bloom after a few years. This problem can be remedied with a simple pruning. Old branches prevent it from sprouting again and should therefore be removed regularly. An annual thinning of the crown is recommended.
Diseases
The garden hibiscus doesn’t bloom? In this case, most gardeners immediately think of an infestation of disease. Before massive interventions are undertaken, however, careful observation should first be carried out to determine whether this assumption is really true. First and foremost, chlorosis should be mentioned here, an insufficient supply of nutrients. Discolored leaves are the first sign. Quick help is offered by fertilizers that provide the missing nutrients.
Pests
Unfortunately, it is not only people who enjoy the impressive flowers of the garden hibiscus. Numerous pests, including
- lice
- and spider mites
are only too happy to nestle on the plant. Spraying nettle stock helps against aphids. Spider mites run away by
- the humidity is increased
- the garden hibiscus is showered and wrapped in foil
- the film must be removed after two days to prevent mold from forming
- then shower the hibiscus again
Conclusion
The garden hibiscus does not bloom? No reason to worry. If you take factors such as site conditions and appropriate care measures into account, the exotic shrub will soon start to bud again. Because often it is only insignificant causes that prevent the formation of flowers. But also serious triggers such as disease or pest infestation can usually be remedied in good time.
