Olive trees are evergreen, but their canopy can look slightly different throughout the year. They produce most of their new growth in late spring and early summer, which is when the head is usually at its fullest and most dense. Olive trees are also commonly pruned to maintain their shape, often in late winter or early spring, which can temporarily make the head appear smaller before the new season’s growth fills it out again. Because of this natural growth cycle and pruning, the size and fullness of the head can vary slightly depending on the time of year. We also often protect our olive trees if temperatures are forecast to drop below around -7°C. While established olive trees can usually tolerate colder temperatures for short periods, providing protection during harsher frosts helps prevent damage and keeps the plants looking their best.
