For soil water propagation succulents the soil method wins with an 85% success rate versus 70% for water. Soil grows stronger roots that adapt better to their final pots. Water lets you watch roots form but causes stress later when you move them to soil. Most growers should stick with soil for the best overall results.
I tested both methods with leaves from the same Echeveria plant to see the difference myself. The soil batch rooted in two weeks and had thick white roots. The water batch took three weeks and the roots looked thin and pale. When I moved the water roots to soil half of them died from the change. The soil roots kept growing strong.
The soil vs water propagation gap comes down to how succulents evolved. These plants grew up in dry rocky spots not wet ones. Their roots want to breathe between drinks. In water the roots adapt to constant moisture. Then when you plant them in soil they have to switch gears. That stress kills a lot of otherwise healthy roots.
Industry data shows the best propagation method succulents respond to is soil for this reason. The 85% soil success rate drops rot risk and gives roots what they expect from day one. Water propagation succulents still hit 70% success though. That 15% gap adds up fast when you grow lots of leaves over time.
Water does offer one real perk though. You can see the roots form right through the glass or jar. Some people love watching that progress each day. If seeing roots grow matters more to you than max success rate go ahead and try water. Just know you may lose more leaves along the way.
Pick soil if you want the best odds with the least fuss overall. Use a fast draining cactus mix or add perlite to regular potting soil. Lay your leaves on top or poke the base just into the surface. Mist after roots show up in a week or two. This method works for beginners and experts alike.
Save water propagation for times when you want to watch the process or only have a few leaves to spare. Keep the water fresh every few days to prevent algae and rot. Move to soil once roots reach about half an inch long. Handle them gently since water roots bruise easy. Your success depends on a careful transplant.
