Olives are one of the few Mediterranean trees that genuinely thrive in a pot, which makes them a favourite for Australian courtyards, balconies, poolside terraces and small backyards. A potted olive gives you the silver-grey foliage and sculptural trunk of a mature tree in a footprint you can move. This guide covers pot size, mix, watering and pruning, and the one thing that decides whether a potted olive lives or slowly declines: light.

Can you actually grow an olive tree indoors?
Not successfully, and it is worth being straight about this. Olives need at least six hours of direct sunlight a day to hold their leaves and stay compact. Even a bright north-facing window in Melbourne or Sydney delivers a fraction of that, and indoor air is far too still for a tree adapted to open Mediterranean hillsides.
An olive brought inside will look fine for a few months, then drop leaves from the interior, stretch towards the window and become prone to scale. If you want the look indoors, bring a potted olive in for a week or two at a time and return it outside to recover.
The good news is that the outdoor version works beautifully across most of Australia. A pot on a sunny patio, balcony or beside a pool gives you everything people want from an indoor olive, and the tree actually stays healthy. If you are after a tree that genuinely tolerates low indoor light, our indoor plants collection is a better starting point.
Choosing the right variety for a pot
Any olive can be container-grown, but some stay naturally compact and need less correcting.
- Arbequina is the best all-round pot olive. Naturally small, densely branched and quicker to bear than most.
- Tolleys Upright has a narrow columnar habit, which suits a balcony corner or a pair flanking a doorway.
- Manzanillo works well if you want table olives from a container and can give it a 600 mm pot.
- Swan Hill is the fruitless option. Choose it for a pot beside a pool, path or entertaining area where dropped fruit would stain paving.

Choosing the pot and mix
Drainage matters more than anything else. Olives tolerate drought far better than wet feet, and the most common way to kill a potted olive in Australia is a saucer left full of water through a wet summer.
- Start at 400 mm wide for a young tree and move up to 500-600 mm as it matures. Going straight to an enormous pot holds too much wet mix around a small root ball.
- Check the drainage holes are open and raise the pot on feet so water leaves freely.
- Use a premium free-draining potting mix. Garden soil compacts in containers and holds too much moisture. A handful of coarse sand or perlite through the mix helps in humid regions.
- Skip the saucer outdoors, or empty it after rain.
- Terracotta suits olives well because it breathes and dries between waterings. Glazed and plastic pots hold moisture longer, so water less often in them.
Ongoing care
Watering
Potted olives need more regular watering than trees in the ground, because a container dries out far faster. Check by pushing a finger 3-4 cm into the mix. If it is dry at that depth, water thoroughly until it runs from the base; if it is damp, leave it. Through a hot Perth or Adelaide summer that may mean every second day; through a wet Brisbane summer it may mean once a fortnight. Never water on a schedule without checking.
Feeding
Nutrients leach out of containers with every watering, so potted olives need feeding more often than trees in the ground. Apply a controlled-release fertiliser in early spring and again in early summer if the tree is carrying fruit. Avoid high-nitrogen lawn fertilisers, which produce soft leafy growth and few flowers.
Pruning
Pruning is what keeps a potted olive in proportion to its container. Prune in late winter before new growth starts, or straight after harvest.
- Keep the canopy roughly the width of the pot, or slightly wider.
- Thin the centre so light and air reach the inner branches. This matters more in humid coastal areas.
- Remove suckers from the base and any shoots below the graft.
- Olives regrow readily from old wood, so a neglected potted tree can be brought back over a couple of seasons.
Repotting
Every two to three years, or when roots circle the base and water runs straight through, move up one pot size in early spring. If the tree is already in its final pot, lift it out, trim the outer roots by 10-15 per cent, and return it with fresh mix. Refreshing the top third of the mix each spring extends the time between full repots.
Position and seasonal care
Give the pot the sunniest spot you have. A north-facing courtyard or west-facing balcony is ideal in southern states; in the subtropics some afternoon shade in midsummer prevents leaf scorch on very hot days.
Potted olives are more exposed to cold than trees in the ground, because the root ball sits above the soil. In frost-prone districts such as the Adelaide Hills, central Victoria or the Southern Highlands, move the pot against a wall over winter or wrap it with hessian on the coldest nights. Established olives handle frost to about -7°C, but a container gives the roots far less buffer.
In coastal gardens olives handle salt spray well, which makes them one of the better choices for an exposed balcony where most trees struggle.
Common problems and fixes
- Yellowing leaves and slow decline is nearly always drainage. Check that the holes are clear and the pot is not standing in water.
- Leaf drop after moving indoors is a light problem, not a watering one. Move the tree back outside.
- Black scale appears as dark bumps on stems, often with sooty mould and ants. Treat with horticultural oil and improve airflow by thinning the canopy.
- Olive lace bug causes yellow stippling on leaves with black specks underneath. Spray horticultural oil, covering the leaf undersides, and repeat after two weeks.
- Healthy tree, no fruit usually means not enough winter chill or not enough sun. Potted olives fruit less than trees in the ground, and in subtropical Queensland a crop is unlikely regardless.
Frequently asked questions
Can an olive tree live indoors permanently in Australia?
No. Olives need six or more hours of direct sun daily, which no indoor position in an Australian home provides. A tree kept inside will gradually drop its inner leaves, stretch towards the light and become prone to scale. Grow it outdoors in a pot and bring it in only for short periods.
What size pot does an olive tree need?
Start at about 400 mm wide for a young tree and move up to 500-600 mm as it matures. Increase pot size gradually rather than planting a small tree straight into a very large container, which keeps too much wet mix around the roots.
How often should I water a potted olive tree?
Only when the top 3-4 cm of mix is dry, then water until it drains from the base. That might be every second day in a hot Adelaide or Perth summer and once a fortnight during a wet subtropical one. Checking the mix beats watering on a fixed schedule.
Will a potted olive tree produce olives?
It can, though usually less than a tree in the ground. Give it full sun, a pot of at least 500 mm, and a variety suited to fruiting such as Arbequina or Manzanillo. In subtropical regions like Brisbane a reliable crop is unlikely because the winters are too warm to set flower buds properly.
How long does an olive tree live in a pot?
Many years, and often decades, provided it is repotted or root-pruned every two to three years and the mix is refreshed. Olives are among the most container-tolerant trees you can grow.
Which potted olive is best beside a pool or path?
Swan Hill, because it is fruitless. Ripe olives stain paving and are slippery underfoot, so a fruitless variety avoids the mess entirely while giving the same silver foliage.

We grow olive varieties suited to Australian containers, from compact Arbequina through to fruitless Swan Hill for poolside pots. Browse the olive trees collection, or see our full range of trees if you are planting in the ground instead.
For in-ground planting, variety selection and climate suitability across Australia, see our guide to growing olive trees in Australia. If your courtyard or balcony needs more than one plant, small-space plants for balconies covers what else works in containers.
