Breeding method of hibiscus;
The best breeding time: generally, it can be bred in spring and autumn.
Best growing soil: suitable for growing on the edge of fertile sandy loam near the water.
Humidity requirements: sunny, slightly shade-resistant, warm and humid climate, drought-resistant, water-resistant and wet-resistant.
Optimum growth temperature: the growth temperature of Hibiscus northeast should be controlled at 18-30.
Best light for growth: hibiscus flowers like plenty of light and can grow well in plenty of sunlight, but it is best to avoid sun exposure.
Matters needing attention in raising grass hibiscus:
Fertilization: Fusang peanuts should be supplemented with phosphorus and potassium fertilizer for a long time. After cotyledons appear, 50-75ppm of 20- 10-20N fertilizer should be applied to increase the true leaf concentration to 100- 150ppm. Alternate application with nitrate nitrogen fertilizer. If you are sensitive to chlorine, tap water should be poured for a period of time, and then poured after chlorine volatilizes.
Key points of watering: water properly according to soil moisture and keep it moist. Be careful not to water the leaves or let dust get on them, otherwise the leaves will rot easily. Don't do this. Water it thoroughly.
Pruning essentials: hibiscus flowers should be pruned in time after each flowering, and the empty branches and seeds formed after the last flowering should be pruned to increase the flower quantity of the next flowering peak, especially after the second peak, so as to ensure the quantity and quality of the next flowering. If it is allowed to grow naturally, the amount of flowers in the later period will also decrease accordingly.
Soil replacement: Hibiscus is usually replaced once every 2-3 years. You can usually apply some fertilizer and water. If the flowers don't grow well, you can change pots in spring and autumn and apply some decomposed livestock manure.
Breeding point: You can use it.

1、
Sowing method
; Hibiscus can be planted every spring, and mature seeds must be used when sowing, because the survival rate of mature seeds of Hibiscus is very strong. The method of planting hibiscus flowers is to soak the seeds in cold water for 3-4 days, and change the water once a day during soaking to ensure the germination rate of hibiscus flowers. When seeds germinate, they should be placed at a temperature of about 32 degrees to accelerate germination. When hibiscus flowers germinate, seeds with buds must be planted on the seedbed. Plantar fertilizer must be applied to the seedbed where hibiscus is planted.
2、
Cutting method
; When cutting, cut the scion into 10- 15 cm long, keep the upper 3-5 leaves or half leaves, cut on the prepared seedbed with the insertion depth of 1/3- 1/2, and then spray water to keep the soil moist. It is necessary to properly shade and promote germination and rooting. After 2-3 new leaves grow, dilute liquid fertilizer can be applied to weed. Finally, transplant and plant in place, and adopt normal fertilizer and water management.
3、
Branch method
; Hibiscus can be planted in spring and autumn. When dividing plants, the stems and buds of the old plants must be cut off for cultivation, which is easy to survive. It was planted that year and opened that year. But when branching, you must choose healthy and full branches for branching.
Pest control: Pests mainly include aphids and red spiders. Lotus is very sensitive to pesticides and is easy to cause phytotoxicity. When using, pay attention to the types and concentrations of chemicals. If necessary, you can choose to use biological agents that are safe for plants, such as 1.2{BF} bitter smoke EC.
Soil culture method of hibiscus;
Hibiscus is usually cultivated in soil by sowing or plant propagation. Mature seeds have strong vitality and great germination potential. Generally, before sowing, the seeds are scalded with boiling water 15 seconds, soaked in warm water at 28 ~ 32 degrees until the seed coat breaks, and then germinated at 32 degrees. Under suitable soil, water and temperature conditions, seedlings
