There are about 200 to 220 kinds of hibiscus. Comes from the warm tropical and subtropical parts of Asia, Africa and America. They grow in the form of woody shrubs or small trees. They stand out for their beautiful flowers composed of large petals and prominent stamens and pistils long. The fruit is a capsule. They need a sunny location, but rather diffused light. Also important is the higher humidity and maintaining the still moist substrate. In winter, move it to a cooler but still bright place and reduce watering slightly. There are also outdoor species that may remain in the garden throughout the year. We use a loam, younger rostlinkám adding rašelinu.Množíme seeds, then it is more durable, but less flowers or cuttings woody twigs, which initially allowed to take root in water. LOCATION: sunny position, in the penumbra fewer blooms, temperature 15 - 25 ° C. If the winter moved to a cooler, but still a bright spot and slightly reduced watering Watering: often likes moisture during limited watering in poor soil before flowering FERTILISING: 1 x per month, if we give the plant a lot of nitrogen has beautiful foliage, but does not flower transplanting : in poor soil after two years lAND: substrate for bonsai AGRO CS, or akadama, peat and sand in the ratio 1: 1: 1 CUTTING: often, we have the dilemma of whether to have a nice shape bonsai, or let create day flowers at the end of branches SHAPING: wire without any problems at any time
Trees of the Hibiscus genus are native primarily to the warm subtropical and tropical regions of Asia. All hibiscus species are highly prized as indoor bonsai (or outdoor flowering trees, in the case of Syrian hibiscus), known for their very rapid growth and tendency to form a strong trunk with dense branching. To enjoy your flowering bonsai in all its glory, it is essential to understand the genus’s basic needs regarding light, watering, and pruning.
For hibiscus bonsai to reliably produce flower buds, they require as much sunlight as possible. Indoors, place it on the brightest windowsill (ideally a south- or southeast-facing window). For tropical and houseplant varieties, the room temperature should not drop below 15 °C even in winter (the optimum is 18–24 °C). During the summer months, all hibiscus plants benefit immensely from being placed in full sun in the garden or on the balcony, where they immediately respond by developing firmer foliage and more vibrant flower colors.
Due to their rapid growth and large leaf area, hibiscus have high water requirements. Keep the potting mix evenly moist and water generously as soon as the soil surface begins to lighten slightly. However, never leave the plant standing in deep water in the saucer for long periods. During hot summers and the heating season, indoor varieties will appreciate having their foliage misted with lukewarm water.
The hibiscus is a vigorous-growing tree that requires high-quality nutrition and a well-draining substrate to produce large flowers and maintain vitality:
Trees of the Hibiscus genus form flower buds on new spring and summer shoots. We perform the main shaping pruning in early spring (in March), when we cut the branches back more drastically to encourage dense branching. Throughout the season, we continuously remove spent flowers along with their stems. As soon as a new shoot grows, we prune it back to the second or third pair of leaves. When shaping with aluminum wire, we work gently and with care on semi-woody branches, as hibiscus wood tends to be brittle.
The succulent leaves and soft buds of hibiscus plants, especially when grown indoors during the winter in warm, dry air, occasionally attract sucking pests—primarily aphids, whiteflies, or leafrollers. At the first sign of an infestation, it is essential to take action promptly. Apply an effective spray (e.g., Mospilan).
Bud drop is most often a reaction to short-term extreme drying out of the root ball, a sudden change in location during bud set, a cold draft from ventilation, or a lack of sunlight. If you move the plant to a stable, sunny spot free of drafts and adjust its watering schedule, the buds will reliably hold on again.
