Sometimes the weather is sunny during the day, the indoor temperature rises, you can open the doors and windows for ventilation, be careful not to put the plant in the tuyere. Four seasons crabapple in the indoor winter, should not be fertilized, to prevent the growth of thin and weak new twigs and leaves, improper cultivation occurred wilt.

If the indoor temperature drops to 0 ℃, cold protection measures should be taken. Three or four thin bamboo sticks can be inserted into the basin as a support, and then the basin is covered with a transparent plastic bag and the lower mouth is sealed. After the room temperature rises, there will be a lot of water droplets in the bag. Remove the plastic bag at this time to avoid causing leaf rot. Indoor heating, stove heating conditions, room temperature can be controlled at more than 15 ℃, the four seasons crabapple grows as usual, flowers continue to bloom, but do not put potted flowers too close to the stove, heating, so as not to burn.

The stems and leaves of the four seasons crabapple are succulent and rich in water.

In order to keep the basin soil moist and dry, avoid excessive watering, basin soil sticky rotten. Watering in winter is generally carried out around noon, which can narrow the temperature difference and is beneficial to plant growth. When the leaves of the plant are dusty, you can choose a sunny day with wind and warm sun, and wash them gently with clean water to keep the leaves clean and bright.

When the weather gradually gets warmer next year, the four seasons crabapple can be moved to outdoor maintenance according to the situation.

1. Moderate watering

Four seasons crabapple likes the humid environment, but in the hot summer, the basin soil should be slightly moist. Watering should not be fixed several times a day or once a few days, but should pay attention to observe the dry and wet condition of the basin soil at any time. It can be watered when the basin soil turns white, and the amount of water should not be too much.

2. Classified fertilization

The summer fertilization of four seasons begonia should be treated differently according to the new and old plants. For the new plants propagated in the autumn of the previous year, some mature thin cake fertilizer and water can be applied after each stubble, and the suitable fertilizer-water ratio is 1:5, once a week, twice a week, and can blossom again after two weeks. When the temperature is above 25 ℃, the old perennial plants or weakly growing plants should stop fertilization and wait until after the summer to usher in the second peak flowering season.

3. Cooling and humidification

The temperature is high and the air is dry in summer. in addition to shading and ventilation, it is necessary to sprinkle water on the ground around the plant many times a day to reduce the temperature and increase the air humidity. Families with conditions can set up a sand bed in a corner of the balcony or a corner of the courtyard, put the plant on the sand surface or sit on the sand bed, and wet the sand while watering the plant. in this way, it can play a better role in cooling and humidifying.

4. Disease prevention and insect control

Begonia is prone to spot bacteriosis under the condition of high temperature and high humidity. At first, dark brown spots appeared on the leaf surface, and gradually spread to a dark brown rib. The same amount of Bordeaux solution can be used to prevent the disease before the disease, and pay attention to improve the cultivation conditions and management methods. In the early stage of the disease, the diseased leaves should be removed and burned in time to prevent re-spread. Summer is the high incidence period of aphids and red spiders, so it is necessary to control them with pollution-free pesticides in time.
