What States in the US Grow Olive Trees

California grows more than 95 percent of U.S. olives, and the most clearly successful growing regions are the interior valleys of central California and southern Texas. Olive trees can also be grown in suitable parts of Arizona, Hawaii, Georgia, Florida, Alabama, and Oregon, but those states vary greatly in reliability for fruit and commercial production. The key is to judge the exact site (winter cold, drainage, summer humidity, and workable soil) not just the state name.

Where Olive Trees Grow Best in the US

Olives are Mediterranean trees. They do best where summers are sunny and dry, winters are relatively mild, and the soil drains quickly after rain.

California is the country’s established olive state, especially in its interior valleys. Those areas combine dry growing weather, irrigation infrastructure, suitable soils, and a long history of olive production for table fruit and oil.

Southern Texas is the other U.S. region with documented success. It has warmth that supports olive growth, but a property still needs protection from occasional hard freezes and must avoid wet, poorly drained ground.

A tree may survive in a state without producing a dependable crop there. That distinction matters if your goal is olive oil, table olives, or a profitable orchard rather than a decorative patio tree.

States With the Best Odds for Olive Trees

Think of olive-growing states in three groups.

Established Commercial Regions

California: The main U.S. olive-producing state, especially the interior valleys of central California.
Texas: Southern Texas has documented successful olive growing. Other parts of the state need a closer freeze-risk and soil-drainage review.

Promising but Site-Specific States

Arizona: Warm, dry areas with irrigation and limited winter cold can support olives.
Hawaii: Warm conditions allow olive trees in selected locations, though local elevation, rainfall, and soil still matter.
Georgia, Florida, and Alabama: Olive trees and small orchards exist, but dependable orchard production remains uncertain.

Emerging or Limited Areas

Oregon: Olive cultivation is emerging, with fewer than 100 acres reported statewide. A mild microclimate may support trees, but it is not a broad commercial olive region.
Other colder states: Home growers may keep olives in containers or protected structures, but an in-ground fruit orchard is much harder to maintain where winter freezes are common.

This is not a complete list of every state where a gardener can own an olive tree. A potted tree can be grown far beyond the regions suited to field production, provided it can be protected from damaging winter cold.

How to Decide Whether Your Site Can Grow Olive Trees

Use this quick screen before buying a tree, leasing land, or planting an orchard.

Site Situation	Best Interpretation	Practical Path
Interior valleys of central California	Successful olive-growing region	Suitable for commercial or home-scale olives if soil, water, and cultivar fit
Southern Texas	Documented successful region	Screen carefully for freezes, drainage, and wet-weather access
Warm Arizona or Hawaii site	Potentially suitable	Confirm irrigation, local winter lows, and drainage
Georgia, Florida, or Alabama site	Possible but higher-risk	Treat as a small trial, not a statewide guarantee
Oregon mild microclimate	Emerging possibility	Start small and expect local variability
Cold-winter location	Poor fit for an in-ground orchard	Grow in a movable container or choose another fruit crop

Step 1: Define Whether You Want a Tree, Fruit, or an Orchard

Decide whether your goal is ornamental foliage, a few homegrown olives, or a crop for oil or sale.
Match your expectations to the site. A surviving tree may still fall short of those expectations.
For an oil or table-olive project, include harvest access, water availability, drainage, and local processing options in the decision before planting.

Commercial production needs far more than a warm summer. Fruit quality and harvest reliability depend on the whole year’s weather and on whether equipment and workers can enter the field when needed.

Step 2: Screen Your Climate Zone and Cultivar

Start with your USDA hardiness zone, but do not stop there.
Olive trees are commonly suited to zones 10 and 11.
Some hardier olive varieties can extend into zone 9 or even zone 8, but confirm the exact rating in the chosen cultivar’s hardiness information.
Compare that cultivar rating with your actual winter lows, not only the average conditions for your city or county.

A hardiness-zone label is a starting screen, not a planting decision.

A protected south-facing wall, a slope with cold-air drainage, or a warmer urban pocket may help a home tree. A low field where cold settles can make the same cultivar fail.

Step 3: Check Freeze Risk Before Planting in the Ground

Look up several years of recorded winter lows for the nearest weather station.
Rule out low spots, hollows, and places where frost regularly settles first.
Treat temperatures below 22°F (-5°C) as a serious warning: they can kill small wood and branches.
Treat a hard freeze below 15°F (-10°C), especially one that lasts for days, as capable of severely damaging or killing an olive tree.

Cold damage is not only a northern problem. In a young Georgia planting, winter lows in the high teens to low 20s, together with extremely wet field conditions, were associated with 15–20 percent stand losses.

Step 4: Test Drainage and Wet-Season Access

Walk the proposed planting area during and after heavy rain.
Reject spots where water stands, soil stays saturated, or equipment and foot traffic would rut the ground.
Favor elevated, well-drained ground with room for air movement around the canopy.
If the soil is slow to drain, use a raised planting area or select a better-drained part of the property rather than putting olives in a wet pocket.

Wet weather can undermine an otherwise warm site. In the Georgia field trial, May rainfall events in excess of 8 inches limited field and cultural work needed for early tree growth.

Step 5: Make a Clear Go, Trial, or No-Go Decision

Choose go if your site has mild winters, good drainage, full sun, and a cultivar suited to your local lows.
Choose trial in an emerging area. Start with a few trees rather than committing to an orchard.
Choose container growing if winter cold is the main problem but you can provide a bright, protected place during freezing weather.
Choose another fruit crop if the ground stays wet, the site regularly has hard freezes, or you cannot protect a container tree.

That decision saves more money and disappointment than trying to rescue poorly placed olive trees later.

What Georgia and Oregon Reveal About Emerging Olive Areas

Georgia is a useful example of why a warm state should not automatically be called an olive-growing state.

A 14-acre commercial olive grove was established in Pierce County, Georgia, in spring 2008. The planting was innovative, but experimental rather than proof that olives were ready for broad statewide commercial production.

The young trees grew despite difficult weather, and some fruiting was expected in their third year. But the project also showed limits on establishment and field work. The UGA Cooperative Extension project concluded that the adaptability and productivity of olives in south Georgia still needed to be determined.

Oregon is another example of a state with interest and small-scale cultivation rather than broad olive production. A mild site with good drainage may grow olives, but cool, wet conditions and winter weather make site selection especially important.

For home growers in these regions, a few trees can be a reasonable experiment. For a commercial planting, start with local weather records, drainage evaluation, and a small trial block before scaling up.

Growing Olive Trees in Cold or Humid States

Olive trees can be appealing in places that are not dependable orchard country. The growing method needs to match the limitation.

Cold-Winter States

In cold-winter areas, an in-ground olive tree can suffer cold injury. A container gives the home grower more control.

Use a large container with freely draining potting mix, place it outdoors in sun during the growing season, and move it into a bright protected area before damaging freezes. Keep the tree from sitting in water, and avoid suddenly moving it from cold darkness to hot direct sun.

A container-grown olive may be a satisfying foliage and fruit experiment, but it should not be treated like a dependable outdoor orchard tree in regions with frequent hard freezes.

Hot, Humid States

Heat alone does not make a site ideal for olives. Humid states can have warm summers but also heavy rain, disease pressure, wet roots, and reduced access to the planting area.

Choose the highest, best-drained part of the yard or field. Keep mulch away from the trunk, avoid crowding trees into stagnant air, and do not assume a warm coastal or southern location will perform like inland California.

Confirm Your Olive Site Before Buying a Tree

Before you order a tree or commit to a grove, make sure you can answer yes to these questions:

Is the site in a region with mild enough winters for the cultivar you chose?
Is the site out of a frost pocket and away from low ground?
Do you have full sun and enough open space for airflow?

If several answers are no, grow olives as a movable patio tree or choose a fruit better suited to your climate. If the answers are yes, start with a cultivar whose hardiness information matches your site and give it the best-drained location available.

Frequently Asked Questions

Does olive trees grow in southern Illinois?

Olive trees may face cold injury in places with severe winter cold. A freeze below 15°F (-10°C) can severely damage or kill an olive tree. A large container that can be moved to a bright protected location is usually the more practical approach.

Can I grow an olive tree in Connecticut?

Olive trees are sensitive to hard freezing temperatures. The tree needs summer sun and winter protection from hard freezes in a bright, sheltered space. An outdoor, permanently planted olive is unlikely to be reliable there.

How long does it take for an olive tree to produce olives?

There is no guaranteed timeline because cultivar, winter injury, pruning, pollination, and site conditions all affect when a tree bears. Treat early fruit as a bonus while the tree establishes rather than as proof of future orchard yields.

What olive trees are best for profitable farming in the US?

There is no single best olive variety for every U.S. farm. A profitable choice must fit the local winter lows, soil drainage, intended harvest method, oil or table-olive market, and available processing. California’s established interior valleys and southern Texas are stronger starting regions than states where olives are still experimental or highly localized.

Are olives grown in the United States?

Yes, olives are grown in the United States. California produces more than 95 percent of the country’s olives, and successful cultivation has been documented in central California’s interior valleys and southern Texas.
