Dryness is a great evil for the hibiscus in the garden and in the room. If you do not have your hibiscus cast for a long time, the leaves will lose their color, turn yellow, hang down, and eventually fall off. You should therefore remember to water your plant regularly and adequately.

If rotting roots have already formed, cut them back and pot your hibiscus.

Disease or pest infestation

Aphids and spider mites can sometimes weaken the hibiscus. Very often, the room hibiscus is attacked in winter, especially when the air is very dry.
The pests are best eliminated by spraying the hibiscus once a week with lukewarm water. In stubborn cases, use soapy water. The leaf underside is treated here.
Preventively, it is advisable to ventilate the room regularly. As a result, the room climate is optimally maintained and greatly reduces the risk of spider mite infestation.
Chlorosis protects against regular fertilization
If the leaves turn yellow over a large area, then it is usually an indication of chlorosis. This is an acute chlorophenyl deficiency caused by insufficient nutrients in the soil, such as boron, iron, magnesium, sulfur or nitrogen. With a suitable liquid fertilizer, applied regularly, prevent a deficiency of the leaf green.
A too dark and too cool location of the houseplant also favors the chlorosis.
The rosemary (Hibiscus rosa sinensis) is best placed in a bright location. A windowsill is ideal for this. However, the hibiscus should not be exposed to the blazing sun of a south-facing window.
In summer he likes to be warmer. But during the rest period, in winter, the exotic plant feels most comfortable at temperatures of 12 to 14° C.
