They like it when the temperature is optimally 60,8-71,6 ° F in summer and 57,2-60,8 ° F in winter. When the temperature drops below these levels, the plant should be moved closer to the window.

If your soil is not particularly rich, you can improve it by mixing in some compost or other organic matter before planting. Hibiscus plants are heavy feeders, so they benefit from being fertilized regularly. Use a complete fertilizer formulated for use on flowers, and apply it according to the package directions.

It is better to water the hibiscus with warm water, in the summer - 2-3 times a week, in the winter - 1-2 times a week. An abundant hibiscus watering leads to the fact that the leaves begin to fade. When the soil in the pot dries out, the leaves of the hibiscus fall off.

Fertilizing and Nutritient

About fertilizer. Since hibiscus is a heavy feeder, it requires fertilizer on a regular basis. For best results, use a fertilizer formulated for blooming plants and apply it from April to October, at least once every 3-4 weeks. An alternative is the use of slow-action granular fertilizers, which are applied annually in early spring. For variegated varieties, fertilizers with a reduced nitrogen content are required.


How to reproduce Hibiscus? The best way to propagate hibiscus is by taking semi-mature stalk cuttings with 3 nodes 7-10 cm long in spring. These cuttings can be rooted in water or wet sand, peat or perlite, however they requires a temperature of at least 71,6-75,2 ° F. Another way to propagate hibiscus is by seed, however seed propagation is only possible if the seeds are pre-soaked using stimulants. The germination process begins by placing the seeds in a wet napkin. As soon as there are little sprouts (3 days later), they are planted in a mixture of sand and peat, then covered with a jar or film and placed under diffused light. Seeds can also be immediately planted in a nutritious mixture, however germination will only occur about 7 days later. It's important to note that when multiplying by seeds, varietal features may not persist.
