The triangular spurge (Euphorbia trigona) is often referred to as the "western cactus" due to its exotic appearance (botanically incorrect), although the care needs of this subspecies of the spurge family, which is widespread as a succulent houseplant, are quite reminiscent of those of cacti. If a triangular spurge is to be cut, protective measures against the poisonous, milky plant sap must always be taken.

Great care must be taken when cutting the triangular spurge

Reasons for the cut

Actually, the Euphorbia trigona is a very grateful houseplant, not least because it does not have particularly high demands and can also deal very well with very dry room air and a sparse supply of nutrients. In many cases, even a relatively small plant pot cannot prevent the triangular spurge from reaching growth heights of over two meters over time. Since these dimensions can be quite impractical indoors, timely pruning can ensure an effective limitation of height growth. In addition, the cut sometimes promotes the branching of the individual shoots, which otherwise often shoot up into the sky like straight columns. From an optical point of view, all cutting measures must be placed very consciously, since the scars on the plant skin caused by the cut remain visible for a long time and can thus significantly impair the aesthetic effect of a Euphorbia trigona. After all, the parts of the plant removed during pruning can easily be used for the propagation of cuttings.

Cut cuttings properly for propagation purposes

Sometimes it can happen that particularly tall specimens of Euphorbia trigona are severely shortened when pruned. In this case, only use the top section with a length of about 15 to 30 cm for propagation. Due to the double wound surface, “middle pieces” from the section material obtained are not only more susceptible, but also visually unsightly. After cutting, the cuttings should be allowed to dry for a few days before finally being placed in suitable succulent soil.

Don't panic: Proceed consciously and minimize risks

The dangers of coming into contact with the toxic milky sap of the spurge family should not be underestimated, especially for small children and pets. Nevertheless, you should not panic in view of this plant species, but rather consciously take certain precautionary measures:

  • Secure tall specimens against falling over (and breaking off) by tying them up
  • Do not leave children and pets unattended in the same room
  • always wear rubber gloves during care measures

tips

The coagulation of the milky juice at the cutting edges of a Euphorbia trigona can be accelerated by placing a cloth moistened with (not boiling) hot water on top. This should be disposed of safely afterwards due to the toxic contents.
