Red hibiscus: general characteristics

The red hibiscus belongs to the Malvaceae family and is native to the islands of the Pacific and Asia. It is an evergreen and as you can tell from its name, the inflorescences are red in color. What makes the latter special is the area in which they form (on top of the branches or between the "axils" of the leaves) and their funnel-shaped size. They can also be double, multiple or simple, the calyx of each flower is made up of 5 sepals and in the corolla there are 5 petals (in the case of simple flowers). The stem column has 5 pistils, is longer than the corolla and above it there are stamens. Hibiscus can be grown both in the garden but can be found as a decoration of the urban environment because it resists nitrogen oxides, sulfur dioxide but also atmospheric agents.


Cultivation

Hibiscus, like other species of Hibiscus, are plants that are very versatile because they can be planted both in pots to be placed inside the home and in your own garden. In the latter case, you just need to make sure that there are the right climatic conditions suitable for the development of the plant. If you are growing inside the house, you need to place the hibiscus in a bright environment, away from drafts and in summer, you need to ensure that it does not exceed 25 ° C. If, on the other hand, it is grown in the garden, it is necessary to ensure that it gradually acclimates to this type of climate. First it is placed in a shady place then, after a few days, it is placed in the sun in the morning and returns to the shade during peak hours. After ten days it can be left in a fixed position.


Red hibiscus: multiplication

The red hibiscus is a flower that multiplies by woody cutting, a practice to be implemented between April and August. A healthy sprout must be removed from the mother plant, based on a piece of wood created the previous year. The latter, to facilitate root formation, must be immersed in rhizogenic powder. At this point, the sprout must be planted in a container containing perlite (better known as river sand) and fertile soil. Then it is covered with transparent plastic fixed to sticks, so as not to suffocate the bud. As for the position that the box must keep until the roots are formed, it is that of exposure to non-direct sunlight and at a temperature of about 21 ° C. The film is lifted every day to check the humidity level of the soil, eliminating any condensation. By about 3 months, the roots will have formed and the shoots will be transferred into pots of about 10 centimeters.


Red hibiscus: diseases and pests

This plant, like many other varieties belonging to this species, can be attacked by phytophages such as mites, scale insects, aphids etc. If they are attacked by these parasites, it is best not to use the same pesticides for plants residing in the garden and for those placed inside the home. Regarding those in the garden, it is good to cover the pot with plastic and wash the plant with water jets, eliminating dust and any insects. Pay close attention to the growth of leaves, flowers and the colors they assume. In the event that the leaves are born normally but, there are no flowers, it can mean excessive fertilization. In this case, just suspend them for a maximum of 2 months and resume them with lower doses. The presence of spots in the lower part of the leaf denotes the presence of cochineal. In this case, just eliminate the parasites with a cotton swab soaked in alcohol and then wash the plant. In addition to these parasites, it is necessary to pay close attention to lice and red spider mites (to eliminate them just spray the hair).
