How to plant euphorbia cuttings

Updated April 17, 2017

Euphorbia refers to the genus of plant species from the Euphorbiaceae family, consisting of a diverse group of about 2,100 plants. Most of them are succulent, which means that they hold water well, and have a poisonous, milky sap. They are most easily propagated as cuttings, and have almost 100-percent success rate. Knowledge of how to take the cuttings and plant them will help you multiply your euphorbia plants quickly and easily.

Cut 4 to 6 inches with a knife from the tip of a stem on the euphorbia plant. Place it in cold water immediately until the sap stops flowing, or briefly expose the end of the cutting to a flame to stop the flow.

Cut off any large leaves right above the bottom of the cutting with a sharp knife. Leave the cutting out to dry for three to four days.

Apply a rooting hormone with 0.1-per cent naphthyl acetic. Brush the hormone onto the end of the cutting. This will encourage roots to grow.

Fill a small pot with a rooting medium consisting of one part peat, one part fine sand and one part perlite. Make sure the pots have good drainage in the bottom of the pot. Place the cutting about 1/3 its length into the rooting medium. Tamp the medium down around the cutting so it stands upright on its own.

Moisten, but do not soak, the rooting medium. Place the cutting in a warm, light room for rooting. Check the cutting daily, keeping the medium moist until the cutting takes root and starts growing on its own. You may then transplant the cutting and decrease watering frequency, allowing it to dry in between waterings.


Wear gloves and protective clothing while handling cuttings as the sap can easily irritate your skin. Conventional rooting hormone has 0.1-per cent indolyl acetic instead, so be sure to look on the package or ask the store clerk for clarification while buying the hormone.
