How can the balcony cabbage turn yellow to raise delicious balcony vegetables?

Most families bring their own balconies, the size of the balcony is secondary, but if there is a balcony, you can plant some flowers and plants above, of course, flowers and plants are loved by young people, after all, they usually use more eyes to play with their mobile phones. Using their eyes for a long time will make their eyes feel very tired. Go for a walk on the balcony and have a look at flowers and grass. You can also change your mood and let your eyes have a rest.

Of course, there are also some people, generally old people or middle-aged people, ha. They like to grow some vegetables on the balcony, such as small cabbages, small chili peppers, spring onions, ginger and garlic, and so on. These dishes are also small and easy to grow, so they are still very popular. However, some people can not raise these vegetables well, and some friends often report to me that a good cabbage turns yellow when it is planted, and it is clearly well watered, but it doesn't get any better. What's going on?.

1. In fact, it is not only Chinese cabbage, but also spring onions and so on. Even chili peppers are prone to dry and yellowing if they are not taken good care of. Why is this the case? First of all, one of the most important reasons should be the lack of water. Water is an indispensable nutrition for plants, including vegetables, but we often put these vegetables in an outdoor environment where they are ventilated and have direct access to light. Moisture is easy to evaporate, and we are usually busy with work or study.

Therefore, ah, there may be a shortage of water supply. But Chinese cabbage, spring onions and so on, this kind of green plant is very easy for us to find their abnormal condition, because the green leaves turn yellow, it is very intuitive and visible to the naked eye, and if the red pepper is a little yellow, if you don't get close enough to see it, it's hard to find it, and if you're careless, it's easy to miss the best rescue time. Maybe your vegetables have been planted in vain in the past few months.

2. Apart from the lack of water, is there any other reason? Of course there is. In fact, some people also pay attention to watering, but why do their own cabbages still turn yellow? This may have something to do with fertilizers, because pakchoi are vegetables, which are different from household plants. Fertilizers bought from flower-and-bird markets are mainly aimed at potted plants rather than vegetables.

Moreover, if you think about it, potted plants are used to watch and watch, and they are not to be eaten in the mouth, but vegetables are to be imported after we have picked them, so of course we can't choose the kind of fertilizer casually. Therefore, ah, don't be lazy in terms of fertilizers. If you really can't find fertilizer for vegetables, rice water is also OK. It's safe and harmless, green and healthy.

Do vegetables need to bask in the sun often? Not necessarily. Chinese cabbages must prefer to bask in the sun, but they should not be exposed too often. After all, these vegetables are relatively small, and the amount of water that can be absorbed by the leaves is limited. What can you do if you lose all the moisture in the sun? Spring onions, ginger and garlic can be a little more casual, their ability to survive and adapt is quite strong, even if they are planted with other plants, they will not be affected, they should continue to grow.
