When to plant Olive tree?

Olive trees thrive in full sun and need a warm, sheltered spot to succeed in temperate European gardens. They are borderline hardy in zones 8a–9, so choose the sunniest, most protected position you have—ideally against a south-facing wall or in a courtyard that traps warmth and shields the tree from cold winds. In colder parts of the UK, Ireland, and the Low Countries, growing in a large container is often more practical than planting in open ground, as it allows you to move the tree under cover in winter. Plant between March and May, once the risk of hard frost has passed and the soil is warming up. Olive trees demand excellent drainage; they will not tolerate waterlogged roots. If your soil is heavy clay, improve it generously with horticultural grit and organic matter, or plant on a slight mound to encourage water to drain away. Sandy soil and loam are ideal. Dig a planting hole twice the width of the root ball but no deeper, so the tree sits at the same level it was growing in the pot. Backfill with the excavated soil mixed with a little compost and firm gently. Space trees at least 300 cm apart if planting more than one, to allow for their mature spread. Water thoroughly after planting to settle the roots, then mulch around the base with gravel or grit rather than organic mulch—this reflects heat, suppresses weeds, and keeps the trunk collar dry, reducing the risk of rot. Stake young trees loosely if the site is exposed, but remove the stake after one growing season to encourage a strong trunk.
