Why did asparagus fern leaves turn yellow overnight? You must have made a mistake in care
Asparagus fern is prized for its emerald-green leaves and elegant form, but during care it is often found that its leaves sometimes turn yellow "inexplicably" overnight. It turns out you did this wrong...
Late summer
Asparagus fern is native to southern and eastern Africa, and is also distributed across central China, the northwest, the Yangtze River basin and various places in the south. From the environments of these places, it can be judged that asparagus fern likeswarm、humidandsemi-shaded, well-ventilatedconditions.
In other words, when caring for asparagus fern, you must pay attention to water management!This includes not only the moisture in the soil, but also the moisture in the air, that is, air humidity. That is:
Soil moisture: Asparagus fern likes humidity, but avoid overwatering, because too much water causes root rot. But the potting soil must not be too dry either; too dry will make the leaves turn yellow and, in severe cases, cause wilting.
Air humidity: Of course, the higher the better. In hot weather, you also need to frequently spray water on the ground around the plant and on the branches and leaves to increase air humidity.
Once you understand the care method, you will know why the leavesturn yellow overnightThe reasons are nothing more than two:
Reason one:Watering too late！
The key is just four words"Water in time!"”When the soil moisture content is about 20%, that is, when it is about to dry out completely, you must water immediately, and even one day late will cause the leaves to turn yellow irreversibly and drop. If you are more than 3 days late, I'm afraid this pot of asparagus fern is completely done for. The picture below shows the state when the soil moisture content is about 20%; at this point it is time to water.
Reason two:Direct air conditioning！
Since asparagus fern likes warm, humid air, ifyou give it thedry, cold airfrom an air conditioner, its leaves will naturally turn yellow.Similarly,the dry, hot air from heating will also cause the leaves of asparagus fern to turn yellow, so the placement of asparagus fern must be chosen with special care, and it must not be too close to air conditioners or heating.
Besides turning yellow overnight, the leaves can also slowly turn yellow, and then you need to consider other reasons, such as an ambient temperature above 25°C, or below 15°C, being placed in direct sunlight, not fertilizing for a long time, etc. Now that you know the reasons why asparagus fern leaves turn yellow, you must avoid them!
