With a knife and pruning shears is how Euphorbia trigona is pruned.
Specifically, the succulent plant in question carries the common name of cathedral cactus. Its pruning demands the donning of long-sleeved shirts, safety glasses and waterproof gloves to protect against the plant's irritating, milky sap. Kitchen tongs need to be used to hold the plant in place while inward-facing and outward-growing branches respectfully get trimmed by hand-held pruning shears and knives.
Generally, the pruning schedule is not demanding. One of two main concerns may prompt trimming the attractive succulent. One will be overcrowding (which is counterproductive to adequate circulation of air, heat, light and moisture). The other will relate to removing diseased, moribund or unattractive parts.
