How can you improve the success rate of succulent leaf propagation?

How are adorable succulents propagated from leaves? It looks like a very simple thing, but it actually is not. There are many little tricks hidden in it, and beginners should master these points that need attention very well, so that in the future they can grow more and even cuter succulents.
For beginners, it is recommended to propagate succulents that are relatively easy to succeed with, such as Graptoveria 'Titubans', Sedum rubrotinctum, Sedum adolphi, Sedeveria 'Letizia', and Echeveria derenbergii.
Plump and intact leaves will increase the success rate of leaf propagation. You just need to place the succulent leaves on top of the soil.
The suitable seasons for leaf propagation are spring, summer, and autumn. Winter is not very suitable, unless you are in a place with relatively high temperatures. Humidity is best controlled at 60%-80%.
The newly grown roots are quite fond of moisture, so you can appropriately maintain the soil's moisture level, but do not expose them to strong sunlight.
The time for sprouting is generally around 10-20 days. This is not absolute. As long as the leaves are still healthy and have not withered, do not give up, and just wait patiently. It is recommended to collect a large number of leaves and propagate them at the same time. In addition, the soil does not have very high requirements, so just wait quietly for the rest.
