Propagating Euphorbia plants is easy and entirely within the skillset of a beginner plant owner. Euphorbia can be propagated through seeds or stem cuttings. While both propagation methods are easy, cuttings are the most common technique. Stem cuttings often grow roots within two to four weeks. The entire process of propagating Euphorbia takes about four to six weeks.
Methods To Propagate Euphorbia
Seeds and stem cuttings are two methods to propagate Euphorbia. Some varieties spread readily by underground runners and can be propagated by division. Seeds may be hard to come by and can take a couple of weeks or up to six months to germinate, depending on the time of year. Stem cuttings are the common method used, and the entire process is straightforward.

Best Rooting Media To Propagate Euphorbia
Use a rich, well-drained potting mix to root Euphorbia stem cuttings. Drainage is vital because while the cutting needs moisture, too much can root the stem cutting or foster mold or mildew. A potting mix formulated for cacti or succulents works well for propagating stem cuttings.
Steps To Propagate Euphorbia
Step 1 - Use clean, sharp pruning shears and wear gloves to protect skin against the sap, which can cause skin irritation.
Step 2 - Trim the end of a stem that measures 6 inches long.
Step 3 - Let the stem cutting sit for several days, allowing the cut end to dry and callus over.
Step 4 - Prepare a 4-inch pot by filling it with well-draining soil or a potting mix intended for cacti and succulents. Make sure the pot has drainage holes.
Step 5 - If using rooting hormone, apply it to the cut end. Rooting hormone is unnecessary but can increase the odds of successfully rooting the cutting.
Step 6 - Water the cutting to moisten the soil.

Caring For Euphorbia Cuttings
Euphorbia cuttings need bright, indirect sunlight to grow. Continue to water the cutting when the top layer of the potting mix is dry. Keep the soil consistently damp but not soggy. Place the cutting in a warm area, away from drafts and vents. Some Euphorbia cultivars prefer increased humidity, so make sure the cutting has its preferred conditions.
Transplanting Euphorbia Cuttings
Gently tug on the cutting after several weeks to determine if it has set roots. The cutting will easily slide out of the potting mix if it doesn’t have roots. If you feel resistance or see new growth, then you know the cutting has rooted. Scale back on watering once the new plant has roots, and only water the new plant when the top couple of inches of potting mix are dry. If you are growing several cuttings in the same container, transplant them into individual pots once they grow several inches and have developed a root system.
