Why do succulent leaves drop off until only bare stems are left?

1Q: The roots have grown quite well, so why does it look so droopy and listless? Thanks!
A: A succulent that has just rooted needs some time to absorb water and recover. Just water it a bit and it will gradually return to a good state!
2Q: Help! I didn't check on it for a day, and my succulent's leaves dropped off with a clatter until only bare stems were left. What on earth is this, and what should I do next? Should I behead it? Can the fallen leaves still be propagated? Has the Echeveria 'Bluebird' also become completely etiolated, and how can I save her originally beautiful appearance?
A: The roots of the Echeveria 'Perle von Nurnberg' have already developed black rot, behead it quickly! Otherwise it will turn black all the way to the top overnight! As for the fallen leaves, some of them should be able to be leaf-propagated, but the lower leaves may not necessarily make it. The Echeveria 'Bluebird' has become completely etiolated, so give it more sun! Otherwise you will regret it even more, hehe~
3Q: My home is in Heilongjiang. I had been keeping it indoors before. Recently the temperature reached around 7-26°C, so I took it outside to grow in the open, in the garden, and after about 4 days it turned out like this. Is this sunburn or cold damage?
A: Above zero degrees it is generally very hard for cold damage to occur. Yours is probably because it was indoors for a long time, and then suddenly placed outside for open-air growing, so the succulent had not yet adapted and got sunburned.
4Q: Mr. Succulent, what cultivar is this?
A: Is it a crested form of Echeveria 'Jin Si Huang'?
5Q: Urgent help needed! Yesterday I bumped my Echeveria 'Yudie' and two leaves fell off. I was afraid it was black rot, so I pulled it out. After sitting out for a night, no more leaves fell off. Please take a look and see whether it needs beheading.
A: Echeveria 'Yudie' is extremely prone to black rot in summer, but I do not see an outbreak point of black rot on the side you photographed. Check the other parts carefully. If it really is black rot, a dry environment can also slow down the speed of black rot. I suggest not potting it up for now and observing for two days.
6Q: Hello, may I ask whether this has become etiolated? What should I do? Behead it?
A: Hello, yes, it has become etiolated! Etiolated Haworthia cooperi and similar plants are not beheaded. They are generally propagated mainly by separating side shoots and root cuttings, so you can only control water to shape them and wait for the new leaves to grow!
7Q: What is going on with the black spots on the leaves, and are the yellowish parts turning to mush?
A: Black spots have many causes; bruises and insect bites are both possible, but yours should not be from insect bites! The yellowing leaves below look slightly shriveled, so it should be that the old leaves are nearing the end of their lifespan, not turning to mush! Relax~~
8Q: Hello, my Haworthia cooperi suffered from lack of water due to neglect. I resumed watering for a month, but it still has not returned to a plump state. What should I do?
A: Haworthia cooperi has thick roots, and the soil mix generally has a larger proportion of grit. If it is still shriveled after watering, some of the original fine root hairs may have dried up and died. Wait patiently!
9Q: Can my leaf cutting survive? It has been planted for a long time, and the leaf has become thinner.
A: Judging by the leaf, it still looks fairly plump, so it can survive; sprouting is only a matter of time. It is just that it does not even have roots yet, so is watering this much really a good idea~
10Q: Why does this leaf only grow roots and not leaves? It has been a long time.
A: For one that has grown roots, bury the roots into the soil first. If it does not sprout, the growth point may be incomplete, or it may be a case where the growth point is complete but it simply does not sprout. This is a matter of probability, so wait patiently a bit longer. I have a leaf that has been going for almost sixteen months, and you did not misread, more than a year without sprouting!
11Q: Are there insects on it?
A: It is hard to see clearly! Green aphids, black fungus gnats, white mealybugs.
12Q: Hello. On the leaves of my Echeveria 'Tippy', some small green dots have appeared. Do you know what is going on?
A: As long as it is not insects, it is fine. Maybe they are pimples, haha!
13Q: The flower center and one small head got sunburned. Can they still recover? How can I make it grow well? The flower center and one small head got sunburned. Can they still recover? How can I make it grow well?
A: As for the sunburned leaf center, judging by the condition of the leaves, there is basically no saving it. It will completely dry up within a few days, and once it is dry, just clean it off. It will grow new leaves again from the leaf center, and you only need to wait patiently.
