Warm, dry summers and mild winters are prerequisites for growing olives.<br>\nOlive trees is an evergreen but does change leaves every three years. This is gradual and begins in the crown.<br>\nOlive trees are slow growers, have a thick trunk and an extensive root system. Olive trees bear olives on average after five years. In temperate regions (Western Europe) olive trees are also widely grown in tubs.<br>\nOlive trees like a sunny south-facing position in a well-drained somewhat calcareous light clay soil. The tree should not be too wet; but also not too dry.<br>\nOne or more holes in the bottom of tubs of olive trees allows excess water to drain away. This will prevent root rot.<br>\nFertilizing olive trees with a slow-release fertilizer is best done in the spring.<br>\nProtect young olive trees from frost during the winter months.<br>\nAn olive tree does not need to be pruned, but the tree tolerates pruning well.
