Beloved by the Ancients, Olives Are Easy to Grow in the Modern Age

Olea Europaea

Are you up for a challenge that is extraordinarily rewarding? Grow olive trees!

Of course, if you’re located in the US and you don’t already live in particular parts of California, Texas, Georgia, Florida, Arizona, Oregon, Alabama, or Hawaii, you’ll have to move there.

These trees require warm summer temperatures as well as about 200 hours of winter temperatures below 45°F. But nothing below about 20°F, mind you.

At around 17°F, you’ll see leaf and small-stem damage, and the tree will likely be killed to the ground at temperatures below 10°F, although mature trees may regrow from the roots.

Anyway, are you settled in your new home, or already based in an ideal location? Good! In this growing guide, we’ll learn more about this Mediterranean import that gifts its caretakers with fabulous fruit, healthful oils, and an attractive addition to the landscape.

Here’s what’s covered in this article:

We’ll share everything you need to know to grow Olea europaea, the tree beloved by ancient Greeks and Romans, and whose fruit has been popularized in the modern age by Italians, Greeks, and Spaniards.

What You’ll See When You Survey Your Orchard

Olive trees are evergreen and can grow to 25-30 feet tall, with a spread just as wide. Their oblong leaves are silverish and grow from branches emanating from a gnarled, twisted trunk.

Some experts believe that more space between trees – about 16-20 feet – will yield better fruit production. If this isn’t practical for your new parcel of land, consider a dwarf variety, which we’ll discuss in a bit.

Mind you, if an expansive orchard isn’t at all what you were after, you should know that the olive makes a fine specimen tree that you can plant and enjoy simply for its beauty, with nary a thought to harvest and curing and pressing and whatnot.

Which Type Is Right for You? (And Where to Buy)

The type of tree you select will depend on what you hope to get out of it. Different cultivars produce different flavors of olives and oil, of course.

You might sample various oils at a farmers market, for example, to select a variety that appeals to you.

‘Mission’ is a variety well-suited to home gardeners who wish to press or cure their harvest. Bob Wells Nursery offers this variety, and it’s available via Amazon.

2-Year ‘Mission’ Trees

The tree they’ll ship to you is two years old.

If you have the patience of Job and don’t mind starting out small, consider this petite ‘Manzanillo’ plant, available from Wellspring Gardens via Amazon.

‘Manzanillo’ O. Europaea Live Plant

They’ll ship you a 3- to 8-inch seedling in a 3-inch pot, along with a fertilizer sample. At maturity, it will reach 30-40 feet with large, great-tasting fruit that are also excellent for producing oil.

‘Arbosana’ is a cultivar that is suited for smaller spaces, growing to be 12-15 feet tall with a spread of 12-20 feet. You can find this type at Nature Hills Nursery.

This Spanish native produces large crops of small fruit with a high oil content that are very flavorful. You’ll receive a tree in a 2.3- to 3.7-quart container.

If you’d like the beauty of an olive tree without the hassle of the fruit, consider ‘Wilsonii,’ a fruitless variety available from High Desert Nursery via Amazon.

Fruitless ‘Wilsonii’ Live Rooted Plant

You’ll receive a 16- to 20-inch tree, or several if you want to take advantage of one of their package deals.

Most cultivars are self-pollinating, though some are not. Furthermore, some self-pollinating varieties produce heavier yields when a pollinator – such as ‘Pendolino,’ ‘Maurino,’ or ‘Leccino’ – is nearby.

No Additives, Please

As we mentioned above, O. europaea is native to regions that have mild, rainy winters and hot, dry summers.

You’ll want to place your trees where they’ll get full sun all day.

These trees are tolerant of a wide variety of soils, including those with somewhat high clay content, as long as there is good drainage.

Planting a young tree in the fall gives it a chance to become well-established. But this is an option only if temperatures in your area won’t drop below 30°F, or if you can protect the tree.

This is because container-grown trees are susceptible to frost damage during their first winter outdoors.

If waiting until spring seems more prudent, hold off until all danger of frost is past. Planting in the heat of summer is not recommended.

Dig a hole about the same size as the container, and about an inch shallower. Water the tree thoroughly, remove it from its container, and untwist or cut any circling roots.

Set the root ball in the hole. Use soil you removed from the hole to build up about an inch of soil on top of the root ball, and grade down from the trunk to the surrounding soil.

Don’t add compost or other soil additives; the plant has to learn to love the native soil. But do top the planting area with mulch.

Prune for More Fruit

Water young trees two or three times a week during their first summer. Give them a good four inches of water at each watering, and hydrate again when the soil dries out.

Once established, they need little supplemental water.

Keep weeds removed from within at least a 3-foot diameter of the young tree.

Fertilize newly planted trees in the spring, after new growth begins. They only need a small amount of nitrogen, which can be delivered via compost, as well as conventional or organic fertilizers.

In its first four years, prune the tree only as needed to maintain its shape.

As your tree matures and begins fruiting, you’ll discover an olive oddity: they never bear fruit in the same place on a stem, so new growth each year is necessary for flower production and fruiting.

Starting in the fifth year of growth, you’ll want to prune not only to increase airflow and maintain height or form, but also with future fruiting needs in mind.

A Bit More on Fruitlessness

If you’d rather not have an established tree set fruit, you can apply a plant growth regulator, or use a strong spray from a hose to blast off blooms.

Some gardeners do this only to areas of a tree that overhang a paved area, in an attempt to reduce the mess from falling fruit.

But, because Mother Nature is persistent and these methods don’t always work, if fruitlessness is truly your goal, you might be better off purchasing a fruitless variety such as the one described above.

Pests and Diseases

Olives aren’t plagued by many pests, although scale can be a problem.

You can prune off infected stems, or treat these greedy critters with neem oil, such as this one from Bonide, available via Amazon.

This 32-ounce spray bottle is ready to use.

For twenty years or so, California olive growers have been plagued by the olive fruit fly, which lays its eggs inside the developing fruit, destroying it.

Management of fruit flies is difficult, and best achieved via clean gardening practices. Some home gardeners have had luck with fly traps, such as these from Terro, available via Amazon.

Trees can also be affected by olive anthracnose, a fungal disease. Treat this problem with a fungicide, such as this one from Garden Safe, available through Amazon.

Young and Bitter

If you’ve provided your olive tree with a happy home, it will begin to bear fruit when it’s around five years old.

Bear in mind, however, that it’s perfectly normal for olive trees to produce fruit only every other year, or to produce alternating heavy and light crops from year to year.

When you harvest your olives depends on what you intend to do with them, and what flavor you seek.

All olives start out green before turning a purplish color, and then deepening to black. The younger the olive, the more bitter it will be.

Typically, olives are harvested at their green stage if their intended use is for the table, although some varieties are best when black.

Olives must be processed – more on this in just a minute – within three days of harvest.

You can either handpick the fruit from your tree, which is quite time-consuming, or you can place a tarp under the tree, and shake the limbs with a rake or other garden implement to dislodge the fruit onto to the tarp for easy pickup.

Preparing your Olives

Raw olives are not tasty. They must be cured to dispel their inherent bitterness, which is caused by the chemical compound called “oleuropein.”

Inventive humans have developed a number of ways to banish the bitterness from these otherwise tasty little ovals, curing them in oil, water, brine, lye, or simply salt.

None of these methods is particularly difficult, but the olives do have to marinate in your chosen mixture for several weeks – so don’t plan for tapenade immediately after harvest!

If it’s oil you’re after, you’ll find as many extraction methods as there are days in a month.

At its most basic, the process entails:

  1. Cleaning
  2. Mashing
  3. Squeezing the mash to extract juice
  4. Separating the oil from non-oil liquid and particulate matter

It can take anywhere from 40-90 pounds of drupes to make one gallon of oil. A mature tree will produce between 30-100 pounds per season, though the giant ‘Chemlali’ may produce close to a ton per year.

Let’s Eat, Already!

You’ve planted, harvested, brined, and pressed. It’s time to savor! We don’t have to tell you that a galaxy of recipes await the olive-laden, but we’ll share just a few to get you started:

Start your meal with a classic Greek salad from our sister site, Foodal. Made with homegrown cucumber, bell pepper, tomato, red onion, basil, oregano, and parsley, this is truly a garden-fresh delight!

My grandparents had an olive orchard that now passed to my mother and father. It stands beautifully up on a hill in the Italian countryside. That is why olives for me are very important. This is a beautiful post with gorgeous pictures and very informative. Thanks for including two recipes that I love!

I just planted 2 arberquina olive trees in South Florida. It might not be cold enough for long enough time down here. They were on clearance at Lowes. 2 trees for $20. So not a big investment. One is 4 ft tall other is about 2ft tall. I’m getting new growth on them already, planted 3 weeks ago. Time will tell.

Very valuable info. If possible, just 1 question. When do the leaves appear for the first time on an olive tree? In three weeks, one month or two?


This is Kenneth in Boise ID. I’m finding that it’s too cold to plant an olive tree in Southern Idaho. Would a greenhouse or covering the tree in the winter months be a solution to having an olive tree until it ages enough to withstand 0° temperatures?


Great post!


I recently purchased 4 olive trees for my grandfather from a local olive orchard. We’re located in central Florida just north of the Tampa Bay area. When would you recommend that I plant them? They are all about 2to3ft tall. We have picked out a suitable location for them. Also was wondering how far I should space them. I purchased the following varieties; Mission, Picual, Manzanilla, and Arbequina. Thanks in advance for any tips or advice.
