Conifers, like most trees, can benefit from some pruning. Tree trimming requirements are a bit different for conifers compared to deciduous trees, so it's important to know the basics.
Most conifers are best pruned during the active growing season. This means that it's necessary to wait until new growth begins to appear in spring. Once new growth appears, usually in the form of young tips at the end of branches, it's pruning season.
