Hibiscus sunflower cultivation methods and precautions

Temperature conditions

Hibiscus has a strong adaptability to temperature and can withstand both cold and heat. However, in the northern winter when temperatures are particularly low, insulation measures are needed.

Lighting conditions

Hibiscus loves light very much. Long-term light can make it bloom vigorously. If the light time is too short, it will be difficult to grow buds and bloom normally.

Fertilizer management

Hibiscus does not require much fertilizer and can still grow and bloom as usual even without fertilizer. However, if some fertilizer is applied appropriately according to its growth conditions, the number and quality of flowers blooming during the flowering period can be greatly improved. This flower generally begins to sprout and grow in May. During its vigorous growth period, it is important to pay attention to fertilizing it mainly with phosphorus and potassium fertilizers. When planting new seedlings, you can first spread a layer of base fertilizer, and then plant the seedlings in. It should be noted that whether it is base fertilizer or ordinary fertilizer, it must be kept at a certain distance from the roots of the plant. Never let the fertilizer directly contact the roots of the hibiscus, otherwise it will easily burn the roots and affect the growth of the plant.

Moisture Management

Hibiscus is relatively suitable for a relatively humid growing environment. During the cultivation process, attention should be paid to watering in time to keep the soil moist, and to avoid excessive drought and lack of water. If it is too dry and lacks water, it will easily cause the flower buds to wilt and fall off. Water immediately after each fertilization to keep the plant moist and prevent root burn.

Pruning and maintenance

Hibiscus should be pruned as soon as possible after the flowering period, and all the withered flowers, branches and seeds should be cut off. This can reduce the consumption of nutrients and increase the number of flowers next time. Every time a flower withers, it is necessary to prune it in time. If it is not pruned, the quantity and quality of the plant's flowers will gradually decrease.

Pest and disease control

Hibiscus often suffers from leaf spot disease, especially in the hot and humid summer, which is the most likely time to induce the disease. In addition to using some liquid medicine for spraying treatment, the more important thing to prevent and control this disease is daily prevention. Pay attention to maintaining air circulation in the environment, promptly prune branches that grow too densely, and prevent the occurrence of leaf spot disease.
