Asparagus is elegant, fresh and refined. It is favored by many literary fans, including Xiaobian, who is also a "asparagus fan". Although asparagus is not difficult to raise, there are many small problems, such as yellow leaves (two asparagus trees in Xiaobian's family are yellow ~). Therefore, many flower friends want to know whether to cut off the yellowing of asparagus leaves and what to do with the yellowing of asparagus leaves. Then, this paper will talk to flower friends about what to do with the yellowing of asparagus leaves in combination with Xiaobian's own experience.
Should the Yellow asparagus leaves be cut off? First of all, let me answer the question that flower friends most want to know - should the Yellow asparagus leaves be cut off and how to cut them;
Under normal circumstances, once the leaves of asparagus turn yellow, they can't turn green again. Only when new leaves grow again can they be green. Therefore, in order not to affect the appreciation of asparagus, Xiaobian suggests cutting off the yellow leaves, and pay attention to pruning in combination with the shape when cutting off.
Next is how to deal with the yellowing of asparagus leaves;
In addition to cutting off the yellowing leaves, what we should do is to find out the causes of the yellowing of asparagus leaves, so as to fundamentally solve the problem of the yellowing of asparagus leaves. Here are some common causes of the yellowing of asparagus leaves. Huayou will check carefully according to the actual maintenance of asparagus.
1. The most common is the yellowing of leaves caused by improper watering. If watering is too much, the yellowing area of asparagus leaves is relatively large, and the branches and leaves will turn yellow. As shown in Figure 2, it is a typical case that too much watering makes the leaves, branches and branches turn yellow; If you water less, it turns yellow from the leaf tip. Usually water and keep the soil slightly wet. Remember not to accumulate water.
2. The reason of light: asparagus is a shade plant. If the light is strong, it will lead to yellow leaves.
3. It is easy to judge the problem of fertilization to see whether it has been fertilized in the near future.
4. The air is not circulating. The maintenance environment of some flower friends is very closed, especially in the north. The air is not circulating, which is also one of the reasons for the yellowing of asparagus leaves.
The leaves of asparagus turn yellow - water yellow (Fig. 2)
Correct daily maintenance method of asparagus 1. Soil. Potted asparagus requires loose soil and good drainage. It is usually made up of half garden soil and half rotten leaf soil, or a small amount of rice bran ash.
2. Light and temperature. Asparagus likes cool and humid environment and grows well under scattered light. It is afraid of strong sunshine in summer, so it should be placed in a ventilated and semi shady place, otherwise the branches and leaves will turn yellow and the leaves will fall off. Winter is not frost resistant. In late autumn, you should move indoors to a sunny place and keep the room temperature above 5 ℃ to survive the winter safely.
3. Moisture. The basin soil should be suitable for humidity. Long term drought will make the leaf tip scorch yellow, while too wet is easy to rot the root and fall off the leaf yellow. When the weather is dry, spray water on the leaf surface and the ground. The water shall be poured thoroughly, and it is better not to dry or pour, so as not to accumulate water. At the same time, do not use the "sprinkling method" to avoid causing wet surface and dry inside.
4. Fertilizer. In order not to make the plant too high, fertilization does not have to be too frequent or too thick during growth. Generally, fertilizer is applied every 10 days in spring and autumn. If the temperature is high in summer, fertilization should be stopped to avoid root rot. Stop fertilizing in winter.
5. Change the basin. Generally, the basin of asparagus is changed once every two years to make the size of the plant and the basin suitable. At the same time, the loose and nutritious basin soil is replaced, and the protective core soil of the original plant needs to be protected to make asparagus grow better.
