Question: Pruning cacti
Pruning a 2 meter high cacti:
Answer: Pruning cacti
in order to answer his question on pruning cacti it is necessary to know the species of his cactus; in fact apart from the opuntie, which produce stems divided into articles, and which are therefore easy to prune, since it is sufficient to remove the more foreign articles to decrease the size of the plant; as regards the other cacti, pruning can lead to completely ruining the aesthetics of the plant.
In most cases the very large cactaceae have a columnar bearing, scarcely branched; any branches can be removed at the base, and also used as cuttings.
If, on the other hand, you proceed by removing the apex of the stems of a cactacea, a large scar will certainly be produced, which will remain permanent on the plant. Over the years, the plant could sprout right on the edges of this scar, producing new branches.
To better indicate how to proceed, it is therefore necessary to know the kind of cactacea that you want to prune, or at least have a photo of it.
