Here’s a video that can help with propagating cactus. These are plants with adapted stems or leaves that retain water. This means they grow with less pressure on them to have efficient root systems. Most other plants rely on their roots to provide water and food, although nature has found some other clever adaptions like some Bromiliads that can grab moisture out of the air using scaly leaves or collect rain in central vases. Cactus and many succulents are easy to propagate since it is less important that they develop their roots fully for survival. As a result you can take cut or broken pieces, let the exposed (newly cut) area dry for roughly twenty four hours to callous over, and pop them into a very efficiently draining medium (like sand) to encourage them to root. Sometimes plants will even start to grow before sending out much in the way of roots. More often, however, they will create a small root system before sending out new growth.
The Opuntia cactus (bunny ears, cholla, pad cactus — among other common names) are probably the easiest to grow from pieces. In nature parts will break off and root where fallen or be carried a little distance away to grow if they are caught on the fur of wildlife. Some of the globular cacti can have ‘babies’ broken off and planted up separately.
Cactus plants can also be grown from seed. Most will need coddling. Seed naturally sprouts in the wet season so expect to start your seeds with plenty of water. Use a very fast-draining medium since water sitting around young plants once they have germinating will make them rot. Young plants can grow in sun, but they will prefer a little protection from scalding hot sunshine. Often seedlings in their natural habitat will germinate in a spot shaded by rocks or overhanging plants to make the first years less demanding.
