Olive tree planters

Which material for an olive tree in a pot

The choice of container shapes the olive tree's health over the long term. Terracotta, the porous material par excellence, lets the root ball breathe and drains away excess moisture: it is the traditional planter of Mediterranean gardens, the one that ages with the tree and weathers beautifully over the seasons. Glazed ceramic planters keep these qualities and offer a wider palette of colours and finishes, from cream to deep blue, so you can match your olive tree to the façade, the garden furniture or the tones of your terrace.

For a more contemporary look, stainless steel planters remain light despite their large size, unalterable and easy to move from one corner of the terrace to another. Galvanised metal planters, treated against corrosion, bring a rawer note while offering excellent longevity outdoors. Whatever the material, choose a planter with thick walls: it protects the roots from temperature swings, in the height of summer as in the depths of winter.

Which planter size for an olive tree

An olive tree grown in a planter develops a root system in proportion to its container. The diameter of the planter should be at least a third of the tree's height, with an equivalent depth to ensure good anchorage and limit wind exposure. Always allow 10 to 15 cm more than the original root ball: the tree then has enough soil in reserve to settle in for the long term.

A young olive tree (trunk up to 10 cm) is happy in a 60 to 80 L planter, i.e. 50 to 60 cm in diameter. A mature tree (trunk of 10 to 20 cm) needs 100 to 150 L, for 70 to 90 cm in diameter. Beyond that, a centuries-old or already imposing olive tree calls for a container of more than 150 L and over 90 cm in diameter: our large planters and our XXL planters are designed for these exceptional trees.

Terrace, balcony or garden: where to place your olive tree

A tree of light, the olive needs at least six hours of sun a day and a spot sheltered from cold winds. On a terrace or in a patio, the space allows you to choose a generous planter from the outset, so repotting is less frequent and the tree can fill out. Placed on its own in a large planter at the entrance to the house, or as a pair on either side of a door, it creates an immediate setting, both elegant and timeless.

On a balcony, the main constraint is weight: a 100 L planter filled with damp soil easily exceeds 150 kg. Check the permitted load before buying, and choose a lightweight stainless steel container or a more modest size, paired with a young olive tree trained as a ball or a standard.

Drainage, potting soil and care

The olive tree tolerates drought, but never standing water at its base. Every planter in this selection has a large drainage hole: add a layer of clay pebbles or gravel at the bottom, then a free-draining potting soil, ideally mixed with sand and a little garden soil. Raising the planter on planter feet helps water drain away and stops the base from staying damp.

For watering, allow a generous drink every eight to fifteen days in summer, letting the surface dry out between waterings, and very occasional watering in winter. Repotting or top-dressing every 3 to 4 years, with a partial renewal of the soil and a fertiliser for Mediterranean plants in spring, keeps the tree vigorous and its silvery foliage dense.

Overwintering outdoors

An olive tree in a planter tolerates the cold, but its roots are more exposed than in open ground. Look for the “frost-resistant” mention on the product page, keep the planter raised so it never stands in frozen water and, during hard frosts, wrap the container in hessian and protect the foliage with a winter fleece.

Frequently asked questions

What size planter does an olive tree need?

At least 60 to 80 L for a young tree, up to 150 L and more for a mature olive. The diameter should be at least a third of the tree's height and exceed the root ball by 10 to 15 cm.

Are terracotta planters frost-resistant?

Yes for the models listed as frost-resistant, thanks to high-temperature firing. During the harshest winters, raising the planter slightly helps drainage and limits the risk of cracking.

How do I move such a heavy planter?

Place the planter on a wheeled plant caddy before filling it: you can then move it easily around the terrace, or bring it closer to a sheltered wall for the winter.

How often should an olive tree be repotted?

Every 3 to 4 years, when the roots completely fill the planter. Between repottings, simply renew the top few centimetres of soil in spring.
