Question: pruning

when pruning hedges


Answer: pruning

Dear Osvaldo,

there is no clear answer to your question, as there are many plants that are used to prepare hedges: conifers, evergreens, flowering shrubs. Pruning is carried out according to the type of plant and its vigor. In general, the shrubs that are used for hedges are vigorous, especially in the case in which climbers are used, such as trachelospermum or wisteria, and therefore it often happens that you have to practice more pruning during the year. The first pruning is generally practiced at the end of winter, when the days begin to lengthen and the night minimums get up; often it is pruning more than cleaning rather than conformation, during which dry or damaged branches are removed, and the first shoots are trimmed, so as to favor a thick development of the shrubs, and to avoid that they tend with time to empty into the part lower part of the stem. There are obviously several exceptions: for example, many flowering plants, such as forsythia, for example, prepare buds already in autumn or winter; these hedges are pruned immediately after flowering, because pruning at the end of winter would deprive us of most of the flowers. As for the "common" hedges, ie most of the evergreen shrubs, with inconspicuous blooms, or in any case not very interesting, the late winter pruning can instead be more vigorous, going to rearrange the crown of the shrubs, to make it fall within the hedge silhouettes. Other prunings are then practiced during the year, when the small new branches tend to develop excessively outwards, the extent of subsequent pruning depends on the type of shrub and its development vigor; plants such as privet are often pruned every month, while the photinias are pruned generally once in late winter, then at the end of pruning and a third time in late autumn. Often the plants that need more care are creepers, which exhibit exuberant behavior, and should be pruned when they tend to take up too much space. The prunings, in addition to containing an overgrown shrub, also serve to stimulate the production of lateral branches, so as to keep the hedge well dense and compact.
