With its exotic, cactus-like appearance, the triangular spurge (Euphorbia trigona) is a very common and popular houseplant. Under optimal location and care conditions, this non-hardy euphorbia species can reach considerable proportions.

The triangular spurge is best propagated by cuttings

Combine pruning and propagation in a targeted manner

The triangular spurge is a species of plant where regular pruning is not absolutely necessary for healthy plant growth. Nevertheless, it can make sense to cut off certain parts of the plant in order to effectively limit the height growth of a Euphorbia trigona. Under certain circumstances, the cut can also ensure stronger branching of the otherwise often tightly columnar growing plant. Before each cut, however, you should be aware that the cuts on a Euphorbia trigona remain visible like scars and consciously apply them accordingly. In addition, the cutting material can be used in a wonderfully uncomplicated manner for the usual propagation through head cuttings.

Tips on how to cut the cuttings

The following things are important when cutting the cuttings and must be observed:

  • Gloves protect against the poisonous milky sap of euphorbia
  • Use a cutting tool that is as sharp and clean as possible
  • allow the cuttings to dry before inserting them into the substrate

While with many other plant species it is advisable to place the cuttings very quickly in the plant substrate intended for the rooting phase, freshly cut Euphorbia trigona cuttings should first be allowed to dry in a rather shady and evenly tempered place for a few days. If this is not observed, rotting can quickly occur at the interfaces of the cuttings. In addition, the substrate for the propagation of this plant species should also be as dry as possible and sandy rather than loamy.

Better dry than too wet

In principle, head cuttings of Euphorbia trigona root relatively quickly and easily under suitable conditions. However, the planters with the cuttings should be kept relatively dry during the first few weeks and should not be watered too often. The triangular spurge is also suitable for the warm and rather dry window sill when propagating cuttings, where other plant species could only be rooted with limited success.

tips

As a substrate for growing the cuttings, you can either use ready-made cactus or succulent soil from a specialist shop, or mix loose soil with sand and gravel.
