How to fertilize hibiscus flowers

1. Fertilization method during pot change and pruning

In the method of applying fertilizer to hibiscus flowers, three things should be done when changing pots: one is to replace new culture soil; the other is to cut off part of the curled fibrous roots that are too dense; the third is to apply sufficient base fertilizer and add phosphorus fertilizer to the bottom of the pot. In order to maintain the beautiful tree shape and the large number of flowers, according to the strong ability of hibiscus hibiscus to sprout branches, pruning and shaping can be carried out before and after the early spring. Except for 2-3 buds at the base, all the upper parts are cut off. Cutting can promote the development of new branches, which will grow more vigorously and the plant shape is also beautiful. After pruning, due to the reduction of consumption of aboveground parts, water and fertilizer should be properly controlled.

2. Fertilization after leaving the room

Fusang is a positive tree species. It should be moved outdoors in early May and placed in a sunny place. At this time, it is also the growing season of Fusang. It is necessary to strengthen the management of fertilizer, loosening soil and pulling grass. Apply thin liquid fertilizer every 7-10 days, watering should depend on the dry and wet conditions of the pot soil, too dry or too wet will affect flowering. After autumn management should be cautious, pay attention to late less fertilization, so as not to shoot autumn shoots. Autumn shoot tissue tender, cold resistance weak, cold weather will suffer freezing injury.

3. Fertilization after entering the room

Fusang is not resistant to frost and must be moved indoors to keep warm after frost falls until early winter. Overwintering temperature requirements are not lower than 5℃ to avoid suffering from freezing damage; not higher than 15℃ to avoid affecting dormancy. Dormancy is not good next year growth flowering is not prosperous. All furniture houses facing south with good thermal insulation conditions can survive the winter. When the weather is colder, they can be covered with paper or plastic film to keep warm. Open the window for ventilation every day during the first day, pay attention to the change of dry and wet soil in the basin, and water it properly. In the coldest days, watering can prevent freezing injury, but fertilization should be stopped.

What about the buds?

4. Winter dormancy

After a period of maintenance, the plants of Fusang will appear aging phenomenon, so it is necessary to take measures to slow down the degradation of plants. In winter it is best to place the plant indoors in a cooler place to allow it to dormancy.

5. Prevention and control of pests and diseases

Because red spiders can cause hibiscus buds to fall, so in the breeding of hibiscus should be placed in a well-ventilated place, if found pests, it is necessary to timely spray treatment.

How to water flowers?

1. Frequency of watering

During the growth of hibiscus flowers, we should always keep the soil moist, so that the stems and leaves can grow rapidly. If watering is not timely, its leaves will shrink, and then gradually turn yellow, finally causing all leaves to fall off. Therefore, we must ensure that we water once a day.

2. Summer watering

In summer, when the weather is hot and evaporation is large, we need to increase the number of watering times, watering twice a day in the morning and evening, so as to meet the growth needs. At the same time, spray some water mist around the hibiscus flowers to create a good humid environment, which is conducive to the hibiscus flowers to spend the hot summer. When it rains more, you need to move the flowerpot indoors to prevent excessive water in the flowerpot.

3. Autumn watering

In autumn, watering can be carried out less frequently. Generally, it is the same as watering in spring. It can be kept once a day. At the same time, watering can be carried out according to the dry condition of the soil, so as to avoid excessive watering and affect hibiscus flowers.

4. Winter watering

In winter, the temperature is relatively low, the plant's various functions will gradually slow down, then to control the amount of water, generally can be watered once a week or so, so that it can have a good cold-resistant conditions, to avoid the phenomenon that the plant is frostbite can not survive. Always keep the pot soil moist, spray some water mist around it on time, and do these well to make the hibiscus flower thrive.

Hibiscus flowers still have a large demand for water and fertilizer, and they adapt to a wide range of soil. Therefore, hibiscus flowers do not have high requirements for growth environment, far better than other flowers. However, in daily maintenance, it is also necessary to carefully cultivate the growth habits of hibiscus flowers, so that hibiscus flowers can grow more beautiful.
