Sowing: harvest the fruit from November to December and knock out the seeds after drying and cracking. The seeds are protected from the scorching sun. The dried seeds were stored indoors in a cool and dry place and sown from March to April in the following spring. Soaking seeds in 45 tons of warm water for 2-3 hours before sowing. The bed soil was screened, the bottom water was poured, and the seeds were mixed with fine sand and then removed from the seedling bed in the open field. The seedlings could emerge in 7-10 days, could be transferred after 40 days, and could be planted after 6 months of cultivation.

Cuttings: the sturdy branches with a diameter of 1.2.1.5 cm were cut around October and cut into cuttings 15-20 cm long. The upper end of the cuttings were about 1 cm away from the bud. Each cuttage contained 3 buds, bundled into bundles, and buried in the sand until March-April of the following spring. The cuttings were taken out in the following spring and soaked for 4-8 hours to make them fully absorb water. Then the cuttings were cut at a depth of 2 to 3 of the length of the cuttings, with a plant spacing of 8 meters and a row spacing of 25 meters. Don't hurt the skin when you insert it. After insertion, timely watering and moisturizing, it is very easy to take root, and the seedling height can reach about I meters in the same year. It can also be cut directly in early spring. It can take root 1 month after insertion. The seedling rates of the two methods were higher. The seedlings can be planted in 3 months.

Ramet: before sprouting in early spring. At first, the branches of the tufted mother plant were cut short from 20-30 cm above the base, and then the mother plant was excavated and divided into several ramets. After planting, a new clump of plants was formed by sprouting from the base of the branches, which could bloom in the autumn of the same year.

Striping: from July to August, the branches are buried in the soil for more than one month, and the branches pressed in the soil take root. After one month, the branches can be cut off from the mother plant and survive the winter.

Pruning: hibiscus needs to be pruned frequently to maintain its beauty. More importantly, it will be trimmed into a shrub, and withered branches and leaves will be removed to keep the whole crown well ventilated and transparent.

Insect pests: the most common pest of hibiscus is the common red leaf mite, which can be sprayed with 73% propargite 3000 times or 20% dimethyl ether EC 1000 times. Small green leafhopper and cotton leafhopper are also common pests of hibiscus, which can be sprayed with 5% carbaryl powder.

Land planting management: hibiscus is generally planted on the edge of the pond or in the sunny part of the courtyard, extensive management can also be done. Water more in the dry season, cut off all the hibiscus branches before winter, or truncate the plants 5 meters from the ground, and cultivate the roots of hibiscus to ensure safe passage through the winter. When the soil is removed and cultivated in the spring next year, new branches will appear on the old plants.

Hibiscus flowers bloom exuberantly, the flowering period is long, can reach at least a month, is a very ornamental flowering plant. Can be planted in the courtyard to beautify the environment. But also potted culture, placed indoors, pleasing to the eye.
