Biological characteristics Fusang originated in southern China. I like a warm, humid and sunny environment. Not cold-tolerant, not tolerant of shade. Branches have strong germination ability and are resistant to pruning.

The optimum temperature for the growth of hibiscus is from March to June 15 ~ 25℃, and from June to next March 13 ~ 18℃. The temperature is not lower than 5℃ in winter. If the room temperature is lower than 5℃, the leaves will turn yellow and fall off, and if it is lower than 0℃, it will be easily damaged by freezing. Above 30℃, hibiscus can still grow normally.

Fusang is resistant to humidity and afraid of dryness. During the growing period, the basin soil is kept moist, and the stems and leaves grow rapidly. If the water supply is insufficient, the leaves will wilt, turn yellow and fall off easily. Because of the low temperature in winter, it is necessary to strictly control the amount of watering, otherwise the cold resistance of plants will be weakened and freeze injury will easily occur.

Fusang is a strong positive plant, and it needs sunshine to grow and bloom normally during the growing period. If the light is insufficient, the buds will fall off easily, the flowers will shrink and the color will be dim. However, when the sun is too strong, Fusang will also burn, so it should be properly protected by shade.

Rich and loose slightly acidic loam is the best soil. Potted soil is a mixture of humus soil (or peat soil), cultivated soil and coarse sand.

Pots of 15 ~ 20 cm are commonly used for the cultivation and management of potted hibiscus flowers. When the seedlings grow to 20 cm high, they should be pitted to promote their branching, and then the height of hibiscus can be controlled by pitting to achieve potted plants. The seedlings are symmetrical and beautiful. Fusang is particularly tolerant of chemical fertilizers. Fertilize 1 time every half month during the growth period or use "Huiyou" 15- 15-30 special fertilizer for potted flowers. Stop fertilizing in winter. Changing pots every spring requires pruning and shaping. Young plants can be lightly cut, and old plants should be re-cut, so as to keep the crown beautiful and promote more branches and flowers.
