How to Grow Olives in Olive Tree Zone 7: A Complete Olive Tree Hardiness Zone Guide

Growing an olive tree outside classic Mediterranean climates is completely possible—especially if you understand olive tree hardiness zones, choose the right varieties, and create the warmest microclimates in your yard.

If you're curious how to grow an olive tree in Zone 7, this guide breaks down everything you need to know to help olive trees grow, survive winter, and eventually produce fruit even in cooler regions.

Understanding Olive Tree Hardiness Zones

Olives naturally come from warm, dry climates, but many gardeners push the limits of the olive tree planting zone. Most olives prefer USDA Zones 8–10, but certain cold hardy olive tree Zone 7 varieties can thrive with protection.

Why Zone 7 Is Challenging—but Possible

A typical zone 7 olive tree must tolerate winter lows down to 0–10°F. Most olives experience damage around 17°F, but some varieties recover well and can fruit reliably with care.

With smart siting, warm microclimates, and seasonal protection, growing an olive tree in this zone becomes a rewarding project.

Choosing Olive Trees for Zone 7

Best Cold Hardy Varieties

When selecting olive trees for Zone 7, choose cultivars known for resilience. Reliable options include:

Arbequina olive trees — Compact, productive, adaptable, and among the best olive tree for Zone 7.
Mission Olive Tree — A classic California variety with strong cold tolerance.
Koroneiki — Excellent for olive oil production and surprisingly hardy.
Manzanilla — Popular table olive and adaptable.

Planting Olive Trees in Zone 7

Finding the Warmest Microclimate

Zone 7 growers should maximize heat around the tree. Ideal spots include:

South-facing walls that reflect warmth
High points in the yard where cold air drains away
Areas with full sun all day

Soil Requirements

Olives love drained soil. To ensure good drainage, amend with compost and check your soil with a simple test: Home Soil Test Guide

How to Plant

When planting a young olive tree, begin by digging a hole twice as wide as the root ball, keeping the top of the root ball level with the ground.

Make sure the hole includes drainage holes if you're planting in a container. See an example here: Planting Olives Video

Caring for Olive Trees in Zone 7

Watering

Olives are drought tolerant, but young trees need regular moisture during the first growing season. Keep soil moist, not soggy.

Fertilizing

Apply a balanced fertilizer in early spring. Acid-tolerant organic blends work well: Acid-Loving Fertilizers

Pruning

Prune to shape the canopy, remove damaged branches, and encourage sunlight access.

Cold Protection

During extreme cold snaps, wrap trees with frost cloth or row cover: Floating Row Cover Guide

Some growers mound soil around the trunk for extra insulation through winter.

Pollination & Fruit Production

Most olives are self-fertile, but yields improve when two varieties cross pollinate. Even in olive tree zone 7, this boosts fruit production, especially for olive oil types.

FAQs: Growing Olive Trees in Zone 7

Can an olive tree grow in Zone 7?

Yes, an olive tree can grow in Zone 7 if you choose cold-tolerant varieties like Arbequina or Mission and give them winter protection and a warm microclimate.

Do I need two olive trees to produce fruit?

Most olive varieties are self-fruitful, but planting two trees improves cross-pollination and can increase yields.

Do olive trees grow better in pots or in the ground?

In Zone 7, pots offer easier winter protection, while in-ground planting provides stronger long-term growth in the warmer parts of the zone.

How many years does it take for an olive tree to bear fruit?

Most young olive trees begin producing fruit in about 2 to 4 years.

What temperature is too cold for an olive tree?

Olive trees may be damaged below 17°F, and temperatures near 10°F can be fatal without protection.

What zones can olive trees grow in?

Most olives prefer USDA Zones 8–10, but cold-tolerant varieties can survive in olive tree zone 7 with proper care.

Is there a cold hardy olive tree?

Yes. Arbequina, Mission, Koroneiki, and Manzanilla are among the more reliable cold-tolerant varieties.

What is the most cold hardy olive tree?

Arbequina is widely considered one of the most cold-tolerant, with Mission also performing well in cooler zones.

Can I leave an olive tree outside in winter?

Yes, if it is planted in a protected microclimate and shielded during freezes; potted trees should be moved to shelter.

Are olive trees better in pots or in the ground?

Potted trees offer flexibility in cold areas, while planting in the ground is better long-term where winters are milder.

How do I protect a young olive tree in extreme cold?

Use frost cloth or row cover, mulch the root zone, and plant it near a south-facing wall to benefit from additional warmth.

Max, it is possible, but you should follow some of the suggestions in this article. It will be more work and you will need to be dedicated to taking care of the olive during the winter months.

Derek, Zone 6 is pretty cold for growing an olive unless you have a heated greenhouse. Good luck.

It is an Arbequina. I’m in zone 6 in Southern Pennsylvania. I started out watering very little and it did not do well. The last month I watered more often and it has not changed. I’m hoping to get it outside in the next couple weeks.

Derek, what kind of olive tree and what zone do you live in? Sounds like your tree is very stressed. How much are you watering the tree? You don’t want to over water the tree.
