Grow your own olives for pickling or making olive oil. We offers olive trees that can be grown outside as far north as Seattle. Although Western, WA may not get enough summer heat to ripen them perfectly. The olive tree ranges in height from 3 to 12 metres (10 to 40 feet) or more and has numerous branches. Its leaves, leathery and lance-shaped, are dark green above and silvery on the underside and are paired opposite each other on the twig. The olive is wind-pollinated. Fruit setting in the olive is often erratic. Growing olives in British Columbia should be seen as a grand and wacky experiment. That said, olive trees will grow in the warmer Zone 8* areas of the Lower Mainland, Southern Vancouver Island and the Southern Gulf Islands. The Arbequina can grow to 15-20 feet tall and 10-15 feet wide. Earliest to bear fruit, usually starting by 3 years of age. The Arbequina Olive is self fertile. Arbequina is a cultivar of olives. The fruit is highly aromatic, small, symmetrical and dark brown, with a rounded apex and a broad peduncular cavity. In Europe, it is mostly grown in Catalonia, Spain, but it is also grown in Aragon and Andalusia, as well as California, Argentina, Chile, and Australia.

Are olives edible off the branch? While olives are edible straight from the tree, they are intensely bitter. Olives contain oleuropein and phenolic compounds, which must be removed or, at least, reduced to make the olive palatable.

Because they are fruit-bearing and evergreen, olive trees need plenty of water. If the trees get too much water, the leaves may yellow and drop. But if the tree gets too dry, which often happens in the winter when watering is less frequent, the leaves will dry out and drop.

Provided with the appropriate growing conditions, this tree can survive in relative neglect for hundreds of years. While olive trees may live to be as old as 1, 500 years, the average lifespan is 500 years.

One must give the olive tree water regularly this is a must. Olive trees that are planted in pots or just planted in the ground, have a compact root ball. It is necessary to ensure that the soil does not completely dry out. Occasional watering is required and needed also in the winter time.

Olive trees need a subtropical climate and do best with mild winters and long, warm, and dry summers. They are sensitive to hard freezing environments. They will grow in climate zones 10 and 11 (see map below). Some varieties are hardy enough for zone 9 or even 8.

During the first few years of its life, an olive tree will grow rather quickly, but growth slows thereafter. If your main interest in growing olives is to harvest the fruit, you can speed the growth somewhat by carefully pruning the tree during its first five years, to create a strong, straight central trunk.

Olives picked off the tree contain a very bitter compound called oleuropein. Harvested olives must be “cured” to remove the bitterness in order to make them palatable. The most common curing processes use brine, dry salt, water, or lye treatments.

The root system development method is mainly determined by the nature of the soil. In some cases, it is reported that olive trees developed roots, which had reached 40 ft. (12 meters) in width and 20 ft. (6 meters) in depth.

Choose olive varieties that are cold-tolerant Typical olives trees will be damaged by temperatures below 17F and may not survive temperatures below 10F. A few varieties are a bit tougher and more likely to make it through cold spells. If you're in USDA Zone 7, we recommend Mission and Arbequina olive trees.

The limbs and leaves spread out to approximately 20 feet. For many gardeners, the tree's spread is the basis for their yard spacing. Planting the trees with a 20-foot spacing between the trunks allows each olive plant to retain its own canopy without intertwining limbs with their neighbor.

Why do olive trees only produce fruit every 2 years (is there a scientific name for this? ) Answer: Some varieties of olives will alternate year bear if left to their own devices. This can be prevented by proper fertilizing, pruning and culling.

To prune an olive tree, choose a time either in late spring or early summer and make sure your tree is at least 3-4 feet tall before pruning. Choose 3-4 strong lateral branches to form your main shape and make slanted cuts to remove branches.

But we can enjoy olive trees (Olea europea) in containers indoors, at least for short periods of time. Because they don't thrive indoors over the long run, it's best to move potted olives outside or plant them in the ground when the weather warms up. If you grow an olive as a houseplant, choose a dwarf variety.
