Propagation by Cuttings

At first, select healthy, mature stems from the Blue Torch Cactus. Use a clean, sharp knife or scissors to make a clean cut just below a node (the part where the spines emerge). After that, so that the cuttings dry for a few days to a week to form a callus.

Once the callus forms, you should ensure a well-draining potting mix with cactus or succulent soil mixed with perlite or sand. Then, you can insert the callused end of the cutting into the potting mix, making sure it stands upright. You can plant multiple cuttings in the same pot.

Also, provide it with indirect sunlight and water infrequently. Over the next few weeks, the cuttings should start developing roots. You can gently tug on the cutting to check if there is resistance, indicating that roots have formed.
