Why do many friends buy green plants that will hang up not long after they are raised, because everyone always does not really understand the following problems!
First of all, if your green plants are bought and hung up within seven days, the most likely is that the water (humidity) is not good, depending on the variety of plant you buy, whether it is drought tolerant or humid tolerant. For example, if you buy a pot of cactus and go back, and water it every day, it will definitely hang it for you. The correct approach should be to first determine how much water the plant likes and then water according to the moisture of the soil. In general, plants that prefer to dry can be watered after they are dry;For plants that prefer moisture, if the soil surface is devoid of moisture, it is time to water. There are also plants that can keep the soil moist all year round. Succulents and desert plants need to be watered strictly during the dormant season and watered less during the growing season.
Secondly, if the green plant you bought hangs up within three months, the biggest possibility is the light. Friends who have a lot of experience in raising flowers can clearly feel it. For example, if you buy an outdoor moon season, but put it in a place where there is not enough sunlight;For example, you buy shade-tolerant ferns and mosses, but expose them to the sun outdoors. This is a relatively chronic process, and it is not visible at once. But the way to judge the lack of light is "long". The way to tell if there is too much light is that the leaves are "scorched" and sunburned.
Another reason is that direct light and scattered light are not clearly distinguished. To put it simply, when you stand on the ground, you can see a visible shadow, which is direct light;There are no visible shadows, i.e., scattered light. No matter how bright it is, it is scattered light. In the shade of the big sun, it is typical of bright scattered light. Some plants need long hours of direct sunlight, but some plants are not sun-tolerant and you have to give scattered light. Scattered light is also divided into strong and weak. You can read a book without turning on the light, there is no visual pressure, and it is bright scattered light. Otherwise, it's weakly scattered light. It's not difficult to arrange the position of the plants according to their light needs. The plants themselves also give clear signals. Plants that lack light tend to overgrow, and the yellow leaves and foliage lose their luster. For example, the seeds grow into bean sprouts, the flesh suddenly jumps very high, the mint branches are thin and long, but the leaves are few, all lack of light. If the light is too strong, the plant can easily get sunburned, the leaves droop, or even dehydrated, and the leaves will be dry and yellow. But there is one point, prolonged direct exposure to sunlight is contraindicated for most plants. Therefore, in summer, it is necessary to try to provide proper shade. In addition, the light intensity of plants through the glass will not be significantly reduced, but the ultraviolet rays will be significantly weakened, so it is more suitable to color or prevent plants from growing. In addition, light can also be used for plant photosynthesis, but at the same brightness, the efficiency of photosynthesis is much lower than that of natural light. If possible, natural light should be appropriately supplemented.
In addition, summer and winter are concentrated feedback on temperature issues. Especially in the south-central region, where there is no heating in winter, many tropical plants are irresistible. Then, in most summers across the country, plants also have a certain probability of dying. The reason is that many non-native plants can easily go into dormant mode at high and low temperatures. In severe cases, it can lead to death. Of course, plants must be ventilated more in the summer. So why are many plants better on the balcony than indoors?In addition to the light reasons, there is also ventilation.
It's also important to learn to observe. The most important organ of a plant is the root. But the roots grow in the soil. Most of the time, the surface of the plant looks good, but in fact the ground has rotted into a puddle of mud. For such silent martyrs, we can only follow their temper, and not be self-centered and operate as a matter of course. We must learn to "communicate" with plants. The way of communication is "observing"!
When the greenery is deprived of water, the leaves of the plant droop and the fresh stems wrinkle;When there is not enough light, the plant will grow in vain, the branches will be thin and soft, the leaf color will be unhealthy, and the old leaves will turn yellow and fall off at the touch of it;When there is too much fertilizer, the sprouts are prone to wilting and the leaf surface is uneven. As for pests and diseases, they are simpler. More observation and early detection is much better than too many back-to-backs**.
In addition to observing the plants themselves, it is also necessary to observe the condition of the soil. For example, when to water and how much to water at one time, there is no standard answer at all, and it is decided according to the dryness and wetness of the soil. For novices, reaching out your finger to touch the wet and dry conditions of the soil surface before watering is a basic operation. Compare the weight of the pot before and after watering, and refer to the next watering. Another extreme to avoid is being too impulsive and frequent. Observe more, operate less, and make another shot when it's time to shoot!This is the style that a flower master should have.
In the end, most of the green plants and flowers are sold to everyone when they are in the best condition. Therefore, the state of the plant slowly "deteriorates", in fact, it is a paradox, because they have been following the aesthetics of their customers, you want shiny green pineapples, they desperately apply water and fertilizer, and even spray polish on the leaves, there is no way, who calls everyone to like it!
Finally, one last word, fertilizers don't need to be messy, just buy a bag of urea and potassium dihydrogen phosphate. I really don't know what is missing, compound fertilizer is also good!
