Olive tree in January: monthly care

Prune olive trees in January or February, during their dormant period when the risk of frost is lower and before new growth begins in spring. Pruning at this time minimises sap loss and stress. Use clean, sharp secateurs for smaller branches and a pruning saw for anything thicker than your thumb. The main goal is to maintain an open, vase-shaped canopy that allows light and air into the centre of the tree. This reduces disease pressure and encourages fruiting wood. Start by removing any dead, damaged, or crossing branches. Then take out any shoots growing inward toward the centre or straight up (water shoots), as these crowd the canopy and rarely produce fruit. Aim to create a framework of three to five main branches radiating outward. Olive trees fruit on one-year-old wood, so avoid heavy pruning of the previous season's growth if you want a crop. Light annual pruning is better than severe cuts every few years. If your tree has become overgrown or neglected, you can renovate it more drastically, but spread the work over two or three winters to avoid shocking the plant. In containers, keep the canopy compact by shortening vigorous shoots by about a third each winter. Remove any suckers that emerge from the base or root ball promptly. Olive trees tolerate hard pruning and will regenerate from old wood if necessary, but regular, moderate pruning keeps them healthy and productive without the need for drastic intervention.
