The triangular spurge (Euphorbia trigona) originally comes from Africa and can grow up to 2 meters high in the wild. In this country, the plant is usually cultivated as a houseplant in a pot and is one of the most popular Euphorbia species for indoor cultivation.

How often does the triangular spurge need to be watered?
This plant species is rarely harmed by too much drought, quite the opposite is the case. You should therefore never water a potted columnar euphorbia before the top layer of substrate in the pot has dried completely. In general, it should only be watered very sparingly, as excessive moisture can cause massive damage to the plant.
What should be considered when repotting this plant?
The cactus-like Euphorbia trigona generally grows relatively slowly and therefore does not have to be repotted too often. You can also easily mix the substrate, which is compatible with the plants, yourself if you do not want to use commercially available succulent soil. To do this, the following ingredients are mixed together:
- Earth with clay content
- peat
- some quartz sand
- Pumice gravel or lavalite from garden retailers
Be careful not to injure the sensitive roots of the plant when repotting and not to come into contact with the poisonous sap of the plant.
When and how can the triangular spurge be cut?
A pruning is not absolutely necessary with this plant, but it can be useful as a care measure to force a targeted branching of the columnar growing plant. Cuttings can also be cut relatively easily and, after a few days of drying, placed in moderately moist substrate.
What pests can threaten the health of this Euphorbia species?
Occasionally so-called mealybugs settle on the columnar euphorbia, but these can easily be rendered harmless with the commercially available means.
Are there diseases that can be dangerous for the triangular spurge?
Like other succulents, the triangular spurge is usually not at all threatened by specific diseases. Only waterlogging or a location that is too dark can significantly impair plant health.
What should be considered when fertilizing this plant species?
During the light-rich growth phase, this plant species can be fertilized moderately about once a month. The fertilizer ration should be in a certain proportion to the size of the plant and the size of the pot, so that individual fertilizer components cannot accumulate in the substrate in a harmful concentration.
What is the best way to get a triangular spurge through the winter?
In this country, this plant is an uncomplicated houseplant all year round, which copes fairly well with evenly warm temperatures. With sufficient brightness, however, wintering at temperatures between 10 and 15 degrees Celsius is also possible.
tips
Always wear gloves for all work such as propagating cuttings or pruning, as the milky plant sap is not only poisonous, but can also be very irritating to the skin if you touch it.
