Common succulent leaf problems are all here

Soft leaves
Lack of water, no watering for a long time, or because long daylight or high temperatures increase the succulent's water needs without them being met in time; some succulents will lose their gloss.
How to tell: after watering, the leaves will become firm and plump the next day.
Adjustment period, for a succulent that has just been potted, the new roots have not yet grown out, so its ability to absorb water is poor.
How to tell: within one month of just being potted.
Dormancy period, because the water absorbed by the roots still cannot keep up with the water consumed by the plant, so softness is inevitable.
The weather is too hot or too cold, causing the succulent to go dormant.
How to tell: temperature above 30 degrees, below minus 5 degrees.
Normal metabolismcausing leaves to dry up; usually the leaves at the bottom of the succulent become soft, and the dried leaves need to be cleaned up in time.
How to tell: the other leaves are firm and plump, with no other abnormalities.
Changes in the growing environment, for example, switching from a high-humidity, low-light environment to one with more light and less water; the succulent does not know how to retain water.
How to tell: moving from a greenhouse into the home, the environment has changed.
A sign of black rot, overwatering, the soil stays moist for a long time.
How to tell: the leaves become soft and fall off, there is black on the leaves or roots, and there has been overwatering, with the soil staying moist for too long.
Solution: promptly remove the leaves that have turned to mush, behead and eliminate the black rot, sterilize the mushy parts, let them dry in the air, and then replant.
Leaves turning to mush
Some experts have said that turning to mush means the succulent drank too much water, and combined with temperature changes, the cell walls burst, so the mushy condition appears.
There are two situations for leaves turning to mush
One is that the mushy leaves are normal;
The other is that the mushy leaves show black, which may be a pathogen infection.
Either way, they need to be removed in time, and the plant should be placed in a ventilated environment with good light. If the stem also has black, it is recommended to cut off the black part and apply carbendazim.
Causes of turning to mush
One, you have just given a heavy watering recently, the succulent drank too much water, and now it is winter, plus a sudden drop in temperature, which will cause turning to mush.
Two, weak light, no ventilation, and moist soil.
Leaves fall off at the slightest touch
There are also several reasons for this situation,
One is too much watering, no ventilation, and also no light
Two is soil compaction, caused by the flower pot not being breathable
Three is more serious, which is caused by black rot
You can observe whether black appears on the roots, stems, and leaves. If so, promptly cut off the black rot areas, apply carbendazim, let them dry, and then plant again.
Four is caused by root rot
If it is not the first two situations, you can gently shake the succulent; if you feel little resistance, you can pull the succulent up, cut off the rotten parts, apply carbendazim, and let it dry.
