Gardening can be a compromise between what you want to plant and what grows well in your area, and the Oregon olive tree is a perfect example of this struggle. While olives aren't recommended for growing in Oregon's climate, Oregon Olive Trees reports success growing olives and making olive oil. Choose a hardy olive cultivar, select a site wisely and provide your tree with winter protection for the best shot at success with an Oregon olive tree.
Select your variety. Oregon Olive Trees recommends the Leccino, Frantoio, Arbequina or Pendolino olive tree for Oregon's climate. The olives can be used for either table olives or olive oil (though you'll need a lot of olives to make oil) and these varieties fare better than others in the colder Oregon climate.
Choose the best site for planting. Oregon Olive Tree suggests an area that has good air circulation, 10 hours a day (or more) of sunlight and well-draining soil. Boggy or poor-draining soil, too much shade and temperatures below 15 F will harm your olive tree.
Test your soil pH at the chosen site using a pH kit. As Santa Cruz Olive Tree Nursery notes, olives like an alkaline soil with a pH of 7.0 to 8.0. If your soil is too acidic add lime to make it more alkaline, using The Garden Helper's soil amendment chart.
Dig a hole twice the size of your olive tree's root ball. Remove stones, twigs and other debris from the site. Remove your olive tree sapling from its plastic container, but take care not to break apart the roots.
Place the tree in the hole at the same depth it was planted in the container. Then cover over the hole with soil.
Water the newly planted tree until the soil is saturated. Continue to water the tree whenever the soil grows dry to the touch.
