Question: araucaria

the araucaria can be pruned

Answer: araucaria

Dear Salvatore,
the araucarias are large trees, which have a development similar to conifers: if you prune the branches, they will tend to quickly produce lateral ramifications that replace the pruned part; if you prune the top, the plant will quickly produce a branch that will replace the one pruned at the top. So generally pruning these plants tends to be counterproductive.
