How to care for Olive Tree

sunlight

Olive trees grow in open, sun-drenched Mediterranean landscapes, so give yours the brightest spot you have indoors. Direct sun helps keep growth compact and supports flowering and fruiting.

Full sun

Place it at a south- or west-facing window where it receives at least 6 hours of direct sun daily. More light is better, especially in winter. A bright indirect spot may keep it alive, but growth will be sparse and it is unlikely to flower.

Turn the pot every week or two so all sides receive light and the tree grows evenly.

watering

Water deeply, then let the potting mix dry partly before watering again. Olive trees handle brief dryness better than constantly wet roots.

Spring - summer

In bright, warm conditions, water about every 7-10 days. Check that the top 2-3 inches of mix are dry, then water until it drains freely and empty the saucer.

Autumn - winter

In lower light and cooler rooms, water roughly every 2-4 weeks. Let more of the mix dry and use the pot's lighter weight as a check before watering.

A hot, sunny spot, small terracotta pot, or fast-draining mix dries quickly, while a cool room or larger pot stays wet longer.

Never leave an olive tree sitting in water. Soggy soil can cause root rot and leaf drop.

humidity

Humidity

35-50%

Olive trees come from sunny Mediterranean climates with dry, moving air. Average indoor humidity is usually fine: they tolerate roughly 30-60%, but do best around 35-50% with good airflow.

Air that stays very dry can cause crisp brown leaf tips, leaf drop, and more spider mite activity, especially near heating vents. Check that watering is also on track before blaming humidity.

Do not try to create tropical humidity for an olive tree - fresh air matters more.

How to help in dry rooms

Move the pot away from radiators, heat pumps, and hot air vents.
Use a humidifier nearby if humidity regularly falls below 30% in winter.
Keep space around the canopy rather than crowding it among damp plants.

temperature

Spring to autumn

18-27°C (65-80°F)

Winter, bright and cool

7-13°C (45-55°F)

Olives come from Mediterranean climates, so they enjoy warm summers and a cooler winter rest. Keep a potted tree above 5°C (41°F), especially if it is young or growing in a small container. Cultivars vary in frost tolerance outdoors.

A bright, unheated room is usually better for winter than a warm spot beside a radiator.

Protect potted olives from freezing glass, cold drafts, and sudden moves between very different temperatures.

nutrition

March - August

Feed a potted olive about every 4-6 weeks while it is actively growing, using a balanced liquid fertilizer at half strength. Apply it to damp soil. Stop feeding in autumn and winter unless the tree is clearly making new growth in a warm, very bright spot.

Nitrogen

Nitrogen supports the olive's silver-green leaf growth. A balanced fertilizer provides enough without pushing soft, weak growth.

Potassium

Potassium supports sturdy growth and can help flowering and fruiting on mature trees grown in strong sun. A general fruit-tree or balanced fertilizer is suitable.

Water first, then feed. If white crust builds up on the pot or leaf tips brown after feeding, flush the soil thoroughly and feed less often.

soil

Gritty, fast-draining soil

Olive roots need air around them and dislike staying wet. Use a loam-based potting mix loosened with coarse sand, grit, or perlite, in a pot with drainage holes.

pH 6,0 - 8,0

This is slightly acidic to mildly alkaline, which suits olives well. Most good-quality potting mixes work; avoid strongly acidic mixes and use a little garden lime only if your mix is known to be very acidic.

Choose a terracotta pot if possible - it helps the mix dry between waterings and reduces the risk of root rot.
