Taking Euphorbia Cuts
Hello. Our Euphorbia has a top part that has grown quite large and the stalk will not be able to support it much longer. it is already leaning a lot (this photo is a few months old and it has gotten larger).
Is it possible to cut the top part off and plant it? How do these plants do with propagation and how do you suggest we do this. How will the bottom respond/heal from it? Is this a good time of year to do this?
I seem to recall there was a solution you suggested to put on this plant if we cut it as it releases some irritating sap.
You can cut below the branching top – leave at least 6 inches of stem below. You should wait until spring, winter is not a great time for this.
First be aware that this is a Euphorbia ammak which has a caustic milky-white latex sap. You need to wear gloves and long sleeves and eye protection when working around this plant. Given its height, this is going to take at least 2 people to safely take cuttings. One to hold the plant, one to do the cutting. If it is taller than it appears you may need a 3rd person to help hold the branch as it is being cut. Please make sure you feel safe with all this before you start. I recommend using a serrated bread knife to cut, and blankets to wrap the branch before cutting.
Basically you need to cut with enough left to be able to plant below the branching. Spray the cut with hydrogen peroxide and set aside to dry for 2 to 3 weeks. Spray the remainder as well, make sure to protect from direct sun until calloused over.
When the branches are fully healed over you can plant them in dry cactus soil and keep dry for a few more weeks. Water only every 3-4 weeks.
Stay safe, Peter
