Reasons and Solutions for Yellowing Leaves of the Heartleaf Aptenia
The heartleaf aptenia, originally named heartleaf mesembryanthemum, is a perennial evergreen herbaceous plant native to southern Africa. The heartleaf aptenia has brightly colored flowers and blooms from July to August every summer. When it is not flowering, it can also be kept at home as a foliage plant for enjoyment. But sometimes we find that the leaves of the heartleaf aptenia have suddenly turned yellow. What is going on? Below, Qinnong Web will explain to everyone what to do when the heartleaf aptenia's leaves turn yellow.
In fact, not all cases of yellow leaves appear for abnormal reasons. The appearance of some yellow leaves is a normal metabolic response of the heartleaf aptenia. At this time, the main feature is that the older leaves at the bottom turn yellow, while the leaves at the top still grow very normally. If your heartleaf aptenia matches this characteristic, then there is no need to panic, as this is a normal growth response of the plant. But if the leaves do not turn yellow in this way, then you need to be careful, as there may have been a problem during care. At this point, you need to find out why. Qinnong Web has summarized three reasons for everyone here.
1. Light
Light can affect the yellowing of leaves, and both too strong and too weak light can cause leaves to turn yellow. If the light is too strong, the leaves will be scorched yellow after being exposed to strong light for a long time; if the light is too weak or even absent, the heartleaf aptenia cannot synthesize the nutrients it needs through photosynthesis, and chlorophyll will also decrease, so the leaves will also show yellowing.
It can be seen from this that giving the heartleaf aptenia sunlight is also a technical task. It can neither be placed directly in a dark corner nor exposed to the sun for too long. A balance point must be found between the two.
2. Fertilization
The heartleaf aptenia needs to be repotted after being grown for a period of time. If the heartleaf aptenia has not been repotted and the soil changed for a long time, the various nutrient elements contained in the potting soil have been exhausted, and the three major elements of nitrogen, phosphorus, and potassium have not been supplemented in time. The plant lacks nutrients, and the leaves appear yellow and thin. At this time, it should be promptly repotted into fertile loam and watered with alum fertilizer water.
Excessive fertilization can also cause leaves to turn yellow. Compared with the previous point, this is easier to judge. The main thing is to check whether fertilizer has been applied recently. If the fertilizer exceeds the plant's needs, the leaves will appear glossy and uneven, then the root system will rot, and the leaves will turn yellow. Fertilization should be stopped, more clear water should be watered, or the plant should be repotted, the roots cleaned, and new soil replaced.
3. Waterlogging
Some flower lovers' heartleaf aptenia potting soil does not have good air permeability, and watering is frequent, which causes the potting soil to remain waterlogged and not dry for a long time. The roots have difficulty breathing, causing the leaves to turn yellow. At this time, the soil should be loosened in time and moisture controlled.
The above is what Qinnong Web has introduced to everyone about the causes of yellowing leaves in the heartleaf aptenia and the methods for handling them. I hope it can be of some help to everyone. The heartleaf aptenia has relatively strong propagation ability. If growing it at home, you might as well propagate an extra pot as a backup, so that even if one pot has a problem, there is still another one available as a backup.
