Olive Tree Growing Guide
Olea europaea
An olive tree can't survive a Canadian winter outdoors, but grown in a container and moved seasonally, it's a genuinely manageable long-term plant.
Light
Full sun outdoors; brightest possible spot indoors in winter
Soil
Very well-drained, slightly sandy or gritty mix
Water
Let soil dry between waterings; tolerates drought better than wet feet
Hardiness
Zone 8–10 outdoors; grown as a container plant in most of Canada
Mature size
3–10 ft in a container, kept smaller with pruning
Winter care
Bring indoors to a cool, bright room before frost
Olive trees are native to Mediterranean climates and can't survive an outdoor Canadian winter — but grown in a large container that moves outside for summer and into a cool, bright room for winter, they're a genuinely realistic long-term plant, not just a short-lived novelty.
Planting & potting
- Use a large, heavy container with excellent drainage holes — olive trees are very intolerant of standing water
- Plant in a very well-drained mix, such as a cactus/citrus blend or standard potting soil amended with perlite or coarse sand
- Repot every 2–3 years into a slightly larger container, refreshing the soil each time
- Move outdoors to full sun after all frost risk has passed, acclimating gradually over a week or two to avoid leaf scorch
Watering
- Let the top 2 inches of soil dry out completely before watering again
- Overwatering, not underwatering, is the most common way to lose a potted olive tree
- Reduce watering significantly in winter when the plant is semi-dormant indoors
- Ensure pots always drain freely; never let a container sit in a saucer of standing water
Winter care indoors
- Bring the tree indoors before the first frost, to the coolest bright spot available (an unheated sunroom or cool window is ideal)
- Olive trees actually benefit from a real winter dormancy period with cooler temperatures (around 40–50°F) rather than a warm living room
- Reduce watering substantially during this dormant period
- Move back outdoors gradually in spring once frost risk has passed, reintroducing sun exposure slowly
Pruning & shaping
- Prune in late winter or early spring before new growth starts
- Remove crossing, crowded, or inward-growing branches to maintain an open shape that lets light reach the centre
- Container-grown olive trees can be kept compact with regular pruning — they respond well to shaping
- Avoid heavy pruning in fall, which can stimulate tender new growth right before the plant needs to go dormant
Common problems
- Leaf drop after moving indoors or outdoors: a normal stress response to the light change — acclimate gradually over a week or two next time
- Yellowing leaves and soggy soil: overwatering or poor drainage — let soil dry more between waterings and check the pot drains freely
- No fruit: most container olive trees in Canada won't reliably fruit due to insufficient sustained heat and the need for cross-pollination, and many growers keep them purely as ornamental foliage plants
- Scale insects (small brown bumps on stems): treat with horticultural oil, especially before bringing the plant indoors for winter

Frequently asked questions
No, not in most of the country — olive trees are hardy only to about Zone 8–10. Growing one in a container that moves indoors to a cool, bright space for winter is the realistic approach here.

- Lilies
True lilies are one of the more reliable bulbs a Canadian gardener can plant — the main threats are the red lily beetle and cutting the stem too short after bloom.
- Wandering Jew (Inch Plant)
Wandering jew is one of the easiest houseplants to propagate — a single cutting in water will root in days, which is exactly how most collections started.
- Boxwood
Boxwood's winter bronzing (leaves turning orange-brown) alarms a lot of gardeners every spring — most of the time it's cosmetic, not a sign the plant is dying.
- Daylilies
Daylilies are about as close as perennials get to 'plant and forget' — the only real maintenance decision is when to divide an overcrowded clump.
