How to grow hibiscus flowers and make them bloom vigorously

1. Soil: Hibiscus does not have very high requirements for soil. However, it is best to use loose, breathable, well-drained sandy soil. You can choose original soil and compost soil, add some coarse sand and base fertilizer.

2. Light: Hibiscus likes a sunny and light-filled environment. It is suitable for growing in sunny places and tolerates partial shade. Choose a sunny place to plant it. It is usually planted by the pond or in the sunny place of the courtyard. Extensive management is also acceptable.

3. Watering: Hibiscus is not drought-tolerant and likes moisture. It is necessary to maintain sufficient water during the growing season. When the flower buds are translucent, water should be reduced appropriately to control the growth of its leaves and concentrate nutrients on the flowers. Reduce watering in winter and do not water too much to cause root rot.

4. Temperature: Hibiscus has poor cold tolerance, so it should be moved indoors in winter and kept at a temperature between 0℃ and 10℃ to allow it to naturally hibernate. In spring, keep the room temperature between 3-10℃, do not water too much, keep the soil slightly moist, and place it outdoors around Qingming Festival. Avoid direct sunlight in summer, and remember to shade it when the temperature is too high.

5. Fertilization: Hibiscus should be fertilized more in spring, and a small amount of phosphorus and potassium fertilizers should be added before and after the flowering period. In winter or spring every year, dig trenches around the plants and apply some decomposed organic fertilizers to facilitate plant growth and promote the growth of flower buds. Hibiscus should be weeded once in summer and winter every year, and topdressed 2-3 times.

6. Pests: Red spider mites are the most common pests of hibiscus flowers. You can use 73% propargite 3000 times solution or 20% dimethyl ether emulsifiable concentrate 1000 times solution for spraying. The harm of small green leafhoppers and cotton leafhoppers should not be underestimated. You can use 5% carbaryl powder for spraying.
