How to raise azaleas in winter
First, I like acid and fear alkali. Second, love wet and fear waterlogging. Third, I like cold, and I'm afraid of heat. Fourth, I like semi-shade and am afraid of strong light. Fifth, I like small winds and am afraid of strong winds. Sixth, I like humidity and am afraid of dryness. Seven, like to give birth but afraid of being fat.
Although azaleas are beautiful, but they are not properly maintained, it is easy to have "one year of flowers, two years of yellow leaves and three years of falling leaves", which makes some people who like azaleas very helpless and have to buy a pot of flowers again.
1. Watering: Teach the best way, that is, try it with a stick or stick it with disposable chopsticks when watering. When you want to pull it out, if it is dry soil, you should water it. If it is wet soil, it can be extended for a few days. If it is wet soil, don't consider watering at all. Like many southern native flowers, azaleas like to grow in acidic soil. If you water the flowers with tap water, you can let the tap water stand for a day or two, and then add a small amount of white vinegar or ferrous sulfate to adjust the pH of the soil.
But there is another way to reduce costs and save money, and that is to use rainwater. Or use snow water. During the rainy season, I hope everyone can accumulate more rainwater to water the cuckoo, and other flowers can also be used, such as jasmine and gardenia introduced from the south.
2. The lighting problem. If we cultivate it indoors, don't put it in direct sunlight. For example, you put it in a room facing south and push it to the south window for two meters. If you put it in the north room, it should be closer to the window, so as to ensure its lighting, and the east and west windows are basically in this position. Therefore, its illumination should ensure that there is enough scattered light, but there can be no direct sunlight, especially afraid of exposure. Rhododendron likes to grow in a cool environment, and the suitable growth temperature is 20 to 25 degrees Celsius. If the flowering period can be controlled at about 15 degrees Celsius, the flowering period can last for a long time. Remind the audience that azaleas are best not to be placed in the bedroom.
Generally speaking, azaleas should be kept in the hall, not in the bedroom, because we all know that plants compete with people for oxygen at night. So in that case, it's best not to put it in the bedroom. The same is true of azaleas, which are best placed in the hall. There are probably several reasons for abnormal defoliation. One is that the water temperature is low when you water it, so you should leave the water for a day or two, and then water it near room temperature. You directly water the water in the tap water pipe and stimulate its roots, which is likely to cause defoliation. In other words, if your fertilizer and fertilizer concentration are too high, it will also cause its leaves to fall off. So generally speaking, our suggestion is to apply thin fertilizer frequently, once every 7 ~ 10 day, or once every half month, and the effect is better. Don't apply too thick fertilizer, which may also cause defoliation. In addition, don't fertilize azaleas when the temperature is high in summer. Professor Chen also said that azaleas like high humidity environment, and the air humidity is not enough, which is also an important reason for azaleas falling leaves. Rhododendron root system is very thin, if watered too much, it is easy to rot and lose leaves. So how can we ensure the humidity needed for the growth of azaleas? You can use a set of pots, that is, the pot inside you is earthen pot, and there is a distance of 5 cm to 10 cm between the pot outside and the earthen pot. This distance can be stuffed with some water-retaining materials like Zhishi, which can be poured on the outer layer to ensure that this place inside will not dry quickly. On the other hand, ensure a certain humidity. Of course, you can also cover the flowers with plastic bags, cut a small hole to breathe, and put the flowers in a large tray to increase the humidity, but be careful not to spray water on them.
3. The problem of fertilization, in the process of maintaining azaleas, there are indeed many friends who are "eager to spend" and often add nutrition to azaleas, but if the method is wrong, it will be counterproductive. When you irrigate the fertilizer, the potassium dihydrogen phosphate and azalea fertilizer you bought should be treated according to the above instructions. How many times should I irrigate, how much water and what concentration? Don't say that you don't irrigate much. In fact, the amount you irrigate is not large, but if you irrigate with high concentration and the nutrients are too high, it will also lead to azaleas withering and even serious death. Therefore, azalea fertilization should not only grasp the quantity problem, but also pay attention to the concentration. If the concentration of azalea is too high by careless fertilization, is there any remedy? Fertilizer can be washed away by spraying water. This matter must be handled with care. When you pour a lot of water into a flowerpot, the water must flow smoothly from the bottom. In this case, the fertilizer can be washed away. Don't accumulate water in the pot after pouring, or there will be problems again. Too much water will drain the roots, which is not worth the loss.
Some people say that she raises a lot of flowers, but she can't raise azaleas well. No matter how you maintain it, you still spend less and have smaller leaves every year. After three years, the flowers are basically useless. I don't know why. After a year of family rearing, the leaves will become smaller and the flowers will become smaller. There will be fewer flowers, because the flowerpots are not changed in time. This is very important. After a year or two, the pot must be changed, mainly to give it a new growth environment. In this new environment, fertilizer is also abundant and has its nutrition. In this case, it can be absorbed into the plant after watering, and the flowers will be bigger and the leaves will grow out.
4。 What problems should we pay attention to when changing pots? That is, after you dig out the basin, clean up the surrounding soil, remove some dead roots, and don't completely break the soil in the middle, then put it in a bigger basin, then water it and put it in a dark place, because in the process of changing the basin, the roots will be injured, so that you can have a recovery time and then return to the normal environment. If you are not completely sure, it will be winter.
5。 Other problems: the azaleas are about to bloom, but the leaves begin to fade and some turn brown. What is the reason? I think there may be two reasons here. One is because of the early management of azaleas, and the air humidity is relatively high. At this time, there may be brown spot disease, and the leaves should turn brown from the tip of the leaf and gradually spread to the whole leaf. I wonder if this friend has paid attention to it. If this is the case, you must use drugs, such as Duojuanling. Another, you can consider whether it is not enough watering, and it is also possible. Spray water on the leaves first, humidify them, wait for the leaves to slow down a little, and then water them. Then water from less to more, don't water a lot at once.
