My daughter and I purchased a tiny African Milk Tree or Euphorbia trigona in April of 2019. It was just a baby then, only about 5-6 inches tall or less.
Now those three columns of the African Milk Tree are almost 36 inches tall! Wow, when they say these houseplants grow pretty fast, it is the truth!
I have a video of that Plant Shopping Haul and grabbed a screen shot of that small plant. This angle makes it look larger but it was a small triple-column Trigona plant.
As it has grown taller, it does seem skinnier than I thought it would be, but perhaps if it had more light, it would have grown a substantially thicker stem.
My daughter and I made quite a Plant Haul that day. If you are interested in seeing that shopping trip, check out how much it has grown since purchased in this video. It is located at about 18:45 in that film.
At the time of purchase, the small columns were only about 5-6 inches high but it had beautiful coloring. I think this one is the Euphorbia Trigona “Rubra” due to its column and leaves being a red color.
What I Learned Growing African Milk Tree
As I have said earlier and in other posts, growing this African Milk Tree is easy and it grows fast so you end up quickly with a larger plant. But be warned! She is a little temperamental.
For instance, she will get used to a certain place in your home where she will seem content, good color, good growth, etc. But if she likes it there, beware of moving her!
It seems to me that she adapts to her surroundings when she has good light and not too much water etc. But if you re-arrange and decide that you’ll change her to the downstairs window or something, she will pout and fling off some of her leaves.
Dropping her leaves seems to me to be a display of her displeasure, but if she quiets back down, and accepts her situation, she will grow leaves again in the spots where she discarded them during her tantrum.
How to Transplant African Milk Tree
Based on how quickly a growing African Milk Tree will outgrow its pot, you will probably need to transplant your Euphorbia Trigona. And here is where you will encounter some of the problems.
Even though this Euphorbia does not really have very much of a root ball, the African Milk Tree may need to be transplanted because it has outgrown the size of the pot in which it is planted relative to its height.
Also as the plant gets taller and more top-heavy, you may want to transplant it into a slightly larger but heavier pot to guard against it being toppled in wind or just in generally moving it around.
I would like to plant mine in a taller hypertufa pot like this one in photo above. Perhaps this much depth is not needed, but I do think the heaviness of the hypertufa will compensate for the larger weight in its columns.
It may make it easier to transplant if you loosely tie the tall columns together to prevent breaking one of the long columns. But all is not lost if one of the columns breaks. Just propagate the piece or pieces.
Propagating The African Milk Tree Plant
Start by allowing the pieces that have broken (or you may take cuttings) to dry or callous for a few days. Then press the lower end into soil and don’t water for about a week or 10 days.
Roots should grow and you can gradually add a bit of water to stimulate the roots to reach into the soil. Bottom watering is best if your planter is not too deep. If it is really deep, you may want to carefully water from the top. Soil must drain well.
But there above is a video of my growing African Milk Tree or Euphorbia Trigona “Rubra.” Well, it really is my daughter’s houseplant and she keeps it in her room sitting in front of an east window. I think it is doing well there.
Are you growing one of these houseplants? How do you like it?
