About Mission
Mission is California's heritage olive — brought by Spanish missionaries in the 1700s and still producing after centuries. A dual-purpose variety that excels as both a cured table olive and a rich, peppery oil olive.
Mission requires 300 chill hours — the number of hours between 32°F and 45°F during winter dormancy. Without enough chill, the tree may fail to flower properly or produce poor fruit.
Common Challenges
Slow to bear (4-5 years); alternate bearing without proper pruning; susceptible to olive knot disease in wet climates.
Common Misconception
Will Mission produce more fruit in colder climates?
Not necessarily. Mission only needs 300 chill hours. Planting in very cold zones (7 or colder) risks winter damage without improving fruit production. The ideal zones are 8-11 where the tree gets enough chill without excessive cold stress.
