1, improper watering. This is the most common reason why asparagus leaves turn yellow. Asparagus is a wet plant. Too much watering will lead to waterlogging, root rot and yellowing of asparagus leaves. Of course, if watering is too little, asparagus will be short of water and its leaves will turn yellow. The standard is to water it when it is dry, but there can be no water.
2, strong light irradiation. Asparagus likes semi-cloudy environment. If there is strong light irradiation, it will * * * leaf cells, resulting in chloroplast injury and yellowing. The solution is to put asparagus in a dark place and spray water on the leaves properly.
The temperature is too low. At this time, frostbite usually occurs. Asparagus will suffer from freezing injury due to long-term exposure to low room temperature, resulting in slow metabolism. The solution is to make asparagus in the environment of 15 degrees, and appropriate astigmatism and weak light irradiation is enough.
4. Improper fertilization. Too much or too little fertilization will lead to the yellowing of asparagus leaves.
Too much fertilization will cause seedlings to burn, too little fertilization will make nutrients in the soil absorbed by asparagus, asparagus will be malnourished and its leaves will turn yellow. The solution is to apply fertilizer properly or change pots frequently. The above is the relevant introduction of this article. I believe you will have a simple understanding of it after reading it.
