Can a succulent regrow its roots?
Once the stem has dried out and calloused over, simply place your plant back in a pot with well-draining cactus or succulent soil and it will grow roots again and continue to flourish!
How do you save a succulent that has no roots?
It will usually take longer to grow new roots during cold months so be patient. You let the plant sit down in semi-moistened soil (using the mist spray) and allow the soil to dry out before you moist the soil again. You can do it outdoor but you have to put them under the shade. Remember do not overwater the soil.
How do I get my succulent to root?
Water: Once the stem has calloused, rest a cutting on the rim of a glass or jar of water, with the end of the stem just above the surface of the water. Choose a sunny spot for your glass. Over time, the cutting will sprout roots that reach toward the water.
