I need more succulents, pronto.
Don’t we all? Your newfound succulent habit could start to get expensive if you had to go buy new plants every time you wanted to expand your collection. Fortunately for you, nature has taken care of that detail. While succulents can be grown from a seed produced by a flower, a much more common method of growing new succulents is through propagation. Succulents have evolved several different methods of asexual reproduction (that is, they make a genetically-identical clone of themselves) that are not found in most other plants.
The easiest method of propagation is via the leaves. Simply select a healthy, mature leaf and pull it from the stem. Make sure that you do not break it off and leave a section of the leaf attached to the plant.
Place the leaves that you pulled onto a tray or a dish and leave them in the sunlight next to their parent plant. You must wait 3-15 days for calluses to form on the ends of the leaf. A callus is like a scab for the plant – it prevents loss of water and invasion by diseases. It is imperative that the leaves receive no water during the callus formation process. This can lead to leaf rot, and will almost certainly halt the propagation process.
Once the leaves have formed calluses, you should move them to a tray or pot that has dirt in it. The leaf can sense the dirt and will begin growing minuscule roots if it has not done so already. Make no attempt to bury your leaves. Leave them on the surface of the dirt, and the plant will do the rest. The leaves (or cuttings) should be misted or lightly watered daily to encourage growth, but do not saturate the soil. Once the plant has established itself (the formation of a rosette or new leaves), it can be re-potted and watering should be reduced.
Is that it?
It is as simple as that! You should find that your baby succulents grow up within a few months or a year. Of course, as with all things in the natural world, there are exceptions. Some succulents will not propagate via this method. Notable examples would be Aloe or Agave plants.

However, some plants take it to the next level. Chances are you own an Echeveria – they are a popular kind of succulent and come in many shapes and sizes; often recognizable by their distinct rosette. If you’ve got one, and you want a lot more, try this:
Pull off the leaves around the base of the stem until 1-2 inches are bare. Prepare those for propagation and set them aside. Use scissors or a knife to cut the stem as cleanly as possible – leave about 1/2 inch underneath the upper, still leafy, part. A clean cut is important because it makes it easier for the plant to callus. Take the top half, the rosette, and give it the same treatment as you did the leaves – leave it out to callus, then plant it in dirt. It should grow new roots in no time! This is a good technique to “get a new plant” if you cause etiolation while the plant is young. And that “stump” you left behind? Leave it! You should see it begins to sprout new buds within a few weeks! That’s three different methods of propagation in just one plant!
Some of my leaves didn’t propagate…
That’s alright! This is a normal part of the process. The success of leaf propagation is determined by a lot of factors – amount of sunlight received, proper callusing, when water was applied, soil presence, and so on. It is not uncommon to have a success rate of <50%.
To improve these odds, rooting hormones are sometimes used. These are commercial products, often powders, that are applied to leaves/stems immediately after cutting to encourage callusing and subsequent root growth. They are effective in increasing success, but not as effective as having proper methodology.
In lieu of buying a rooting hormone, honey has been shown to be effective. Simply dipping the tips of your leaves or stems in honey before setting them out to dry can increase their chances of survival. This is an excellent low-cost alternative, as most households have honey (because it literally never expires). If you choose to go this route, make sure you are using real, natural honey – not the artificial kind!
