Hibiscus is a plant with beautiful leaves. The main ornamental effect of bonsai made from it is to observe the piles and leaves. Let's take a look together.

Yu furong bonsai making

Cultivation soil: Hibiscus has a well-developed root system and a large plant shape, but its root system can only move in a small soil range due to the limitation of flowerpot containers when potted. Therefore, potted hibiscus flowers have strict requirements on soil, and the culture soil needs to be prepared manually. First, choose raw materials, such as garden soil, humus soil, river sand, peat, manure, etc. Secondly, determine the reasonable proportion: 5 parts of garden soil, 3 parts of humus soil, 2 parts of slag ash and farmyard manure; Finally, in order to kill the bacteria in the culture soil, chemical disinfection or heating disinfection can be carried out.

Transplanting: In order to prevent crowding, transplanted seedlings should be transplanted to the open field, protected land or potted plants in time for maintenance. Note that seedlings are generally not suitable for potted plants. Because potted seedlings are not as fast and strong as those planted in the field, and they form quickly and have developed roots. Therefore, potted hibiscus usually adopts old piles over 1 year.

Potting: Transplanting molded seedlings over 1 year old into pottery pots or bonsai pots for cultivation. Pay attention to the size of seedlings and flowerpots when serving pots.

And pay attention to protect the integrity of the formed root system. Pruning: it can become a natural shape, with layered clouds and curved shapes. Generally, there are 3-4 main branches with 3-4 layers. The lower floor is big and the upper floor is small. The lowest branch can also become a relatively long floating branch, hanging down from the lower part of the basin surface. Plastic surgery should be performed in March-April and August-September in the slow growth period. The branches of hibiscus are thin and brittle, so be careful when shaping, and don't use too much force.

Protection of Jade Furong Bonsai

Illumination: Emerald hibiscus likes plenty of sunshine and is not tolerant of shade. Even in hot summer, there is no need for shade. Direct sunlight is more conducive to the good growth of hibiscus and improve its ornamental value. If the light is insufficient, the branches and leaves of hibiscus will be white and long, the plant shape will be loose and not compact, and the leaf color will change from silvery white to light green. If you need to move into a cool place indoors to watch, it can only be for a short time, so as not to affect the growth of plants. However, the seedlings at seedling stage are afraid of exposure to the hot sun, so attention should be paid to proper shading.

Watering: Emerald Hibiscus is drought-resistant and water-resistant. When watering, we should master "dry but not wet" and never let the basin soil get too wet and get wet. Water the hibiscus thoroughly at ordinary times, and spray water on the hibiscus flowers when the air is dry to increase the air humidity and avoid burning the leaves. Drainage should be done in time to prevent waterlogging in rainy season, otherwise the accumulated water in basin soil will easily lead to the root rot of hibiscus. The jade hibiscus placed outdoors should be checked in time after the rain, and the accumulated water in the basin should be poured out.

When the temperature is low in winter, we should pay more attention to controlling crying. Fertilization: I like fertilization, and I want to master the principle of thinning first and then concentrating, slowly applying a small amount, and reasonably coordinating nitrogen, phosphorus and potassium. Topdressing cake fertilizer and water once every 10~ 15 days in the growth period, topdressing phosphorus and potassium fertilizer in the late growth period and fruit-setting period after flowering, and spraying 0.2% urea and 0. 1% potassium dihydrogen phosphate on the leaves. The use of organic fertilizer must be decomposed,

When the weather is hot, stop fertilizing or apply a small amount of inorganic fertilizer. Potted hibiscus is changed every two years, and basal fertilizer is applied in autumn or when changing pots. Generally, decomposed cake fertilizer or manure should be used, and each pot is 20 ~ 100g. Pests and diseases: strong disease resistance, few pests and diseases, such as leaf black spot or brown spot, powdery mildew, aphids, red spiders, scale insects, leaf-eating pests, etc. , should be timely inspection and prevention. Leaf spot can be controlled with 50% carbendazim or 75% chlorothalonil 800~ 1000 times solution, and powdery mildew can be controlled with triadimefon 1000 times solution. Hibiscus aphids are heavy. Once found, they should be sprayed in time to kill mites 1000 times. In the larval stage, the scale insects were killed at a rate of 40% from May to July, and sprayed with 1000 times solution for 2-3 times. Use 15% EC to control red spider 2000 times.

Potted hibiscus mutabilis is suitable for balcony, indoor and courtyard. Touching the leaves with your hands makes you feel cool, comfortable and refreshed. Therefore, it has gradually become more and more popular indoor potted ornamental plants.
