How to grow olives
Our detailed growing guide will help you with each step in successfully growing Olives.
Getting Started
Olives are drought-tolerant evergreen trees with shimmering silvery foliage that love to bask in a warm, sunny and sheltered position. Whether you grow them in the ground or in a large container, they will add an instant touch of the Mediterranean and may sometimes in hot summers and southern gardens, reward you with a crop of attractive-looking fruit that need special preparation to make them edible.

Planting
Olives are available in many sizes from mature old trees with beautiful gnarled trunks that make the perfect focal point in a large garden, to half standards that take up very little space.
Plants can be planted in the soil in cool climates if you have a very sheltered town garden, but are more suitable for growing in large containers that can be given a sunny-spot outdoors in summer, then moved into a frost-free place overwinter.
Planting in the ground is best carried out in spring. Select a well-drained, sheltered site against or near a sunny wall. Stake plants until established.
Alternatively, plant in 30-35cm (12-14in) pots (or large enough to accommodate roots comfortably) filled with gritty, loam-based compost, mixing in some controlled release fertiliser granules.
Plant Care
Prune olives in early spring to keep an attractive shape and to remove any dead, diseased or dying branches. To restrict the size of a pot-grown olive, tip prune the main branches, cutting back to a good replacement shoot each year.
Many olives are hardy, but branches can still be damaged by severe frosts. Store in a frost-free place if grown in pots or cover the branches with horticultural fleece.
Plants grown in pots should be raised up on pot feet to allow excessive moisture to drain away.
Do not move pot-grown plants outside for the summer until all danger of frost has passed.
