Is there any way to fix the yellow leaves of double-petaled hibiscus?

Double-petaled hibiscus likes fertile acidic soil. If the pot soil is not fertilized for a long time, the soil will lack fertilizer, and the plant will not be able to keep up with the nutrition and will turn yellow. If the soil is not acidic enough, the plant will also turn yellow. It is recommended to apply liquid fertilizer or nitrogen, phosphorus and potassium compound fertilizer once a month during the growth period, which is conducive to the luxuriant branches and leaves of hibiscus. Apply phosphorus and potassium water fertilizer once every 10 days during the flowering period to promote bright colors and extend the flowering period. You can also apply ferrous sulfate once a month to promote soil acidity, which is conducive to the soil not being compacted, and the hibiscus grows vigorously.

When we first planted double-petaled hibiscus, the soil should be fertile, loose and well-drained. The potting soil should be mixed with leaf mold, garden soil and coal slag, and sufficient organic base fertilizer should be applied to facilitate the rapid growth of hibiscus. Ordinary clay cannot be used for hibiscus cultivation. This kind of soil has poor water leakage and is easy to harden, which affects the malnutrition of the plant and causes yellow leaves. In addition, hibiscus grows very fast, so the flowerpot should be slightly larger to provide for the growth of the root system.

Double-petaled hibiscus is drought-tolerant and does not like waterlogging, but it cannot be left without water for a long time. Watering the pot soil too dry or too wet will cause the leaves of the plant to turn yellow. It likes a humid environment. During the growth and flowering period, it is better to see dry and wet soil. In the hot summer, sprinkle water on the plant to keep it moist. If the soil is dry, water it after sunset. After autumn, reduce the amount of watering for hibiscus to prepare for winter. Because it is not cold-resistant, it is better to keep the pot soil slightly dry in winter, otherwise wet soil will cause frost damage and yellow leaves.

Double-petaled hibiscus is generally not susceptible to diseases and pests, but the environment must be kept ventilated when maintaining hibiscus, otherwise aphids, red spiders and other pests will suck the sap of the plant, causing the leaves of the plant to lose their green color and turn yellow; if the branches and leaves grow too densely and are not airtight, the leaves will also turn yellow. Therefore, environmental ventilation is very important. Hibiscus is resistant to pruning. Appropriate pruning of crowded branches and leaves and dead flowers is conducive to air permeability and light transmission between plants, avoiding diseases and pests and promoting healthy growth and gorgeous flowering.

It needs sunlight all year round, but hibiscus grown in the north needs to be moved indoors to a sunny location in winter. Because it is not cold-resistant, the room temperature should not be lower than 5 degrees, otherwise it will suffer from frost damage and the leaves will turn yellow.

How to water hibiscus during flowering period

Hibiscus flowers on new shoots, and can only bloom continuously if it continues to grow vigorously. Therefore, it is necessary to fertilize frequently during cultivation to promote its vigorous growth. It is advisable to apply liquid fertilizer once a week during the growing season.

Hibiscus consumes a lot of water. It needs sufficient water during the growth period. It should be watered once a day, but the most important thing is not to dry the pot soil or retain water. It can be watered every two days in the rainy season. Pay attention to sufficient fertilizer and water, which is the key to growing good flowers. If the room temperature of hibiscus flowers in the north is kept at 15-22℃, the flowers of hibiscus flowers will fall in one day. If there is sufficient sunlight, water and fertilizer, hibiscus flowers can bloom every day. The flowers are bright and beautiful, and they are good flowers for indoor and outdoor use.

In spring, the stems and leaves are growing vigorously, so water them every two days. After the flowering period, place the mulberry tree outdoors in a sunny place and water it three times a week. In summer, when it enters the vigorous flowering period, water it once a day, keep the pot soil moist, keep the high temperature and dry air, pay attention to ventilation, and prevent the occurrence of red spiders and scale insects.

In autumn, move the potted hibiscus indoors and water it twice a week. Spray water when it is dry to improve the air humidity and promote growth and flowering. In winter, place it in a sunny place indoors and water it twice a week. Do not make the pot too wet or too dry.

How to prune hibiscus

In the first year after buying it home, if it is not very large, there is no need to prune it. Pruning can be done during the annual growing season. If you prune during the growth stage, you can cut off old and weak branches to avoid excessive consumption of nutrients.

You can also choose to prune after flowering, just slightly prune the branches that have bloomed, and fertilize once after pruning, so that you can add some nutrients, so that you can grow better. At this time, cutting off the branches is mainly to avoid consuming nutrients. So pruning is necessary.
