Propagating Cactus. Their are two chief methods to disperse cactus: out of seeds, also from cuttings. Drawbacks into growing by seed would be the time necessary to develop from seed to seedling, to move prepared. Experts are you can develop a lot in a little place, and can buy seeds from all around the country/world etc..
The other solution is to take cuttings from cactus, let them dry/callous, then replant in to containers. Generally you’ll acquire new expansion from the cut places as well so that you have a cycle of cactus to lower out of, restricted only by their expansion period. This way takes more distance though however growth is faster since the parent cacti have established roots and much more size.
