Olive trees need a subtropical atmosphere and do best with mellow winters and long, warm, and dry summers. They are touchy to hard solidifying conditions. They will grow in atmosphere zones 10 and 11. A few assortments are strong enough for zone 9 or even 8.

Temperatures beneath 22ºF (- 5ºC) will execute little wood and branches. Solidifying conditions enduring days or a hard stop, beneath 15ºF (- 10ºC), will kill or seriously harm an olive tree. It is ideal to abstain from planting olive trees in circumstances where there is a high danger of ice during blossom (late April to mid-May) or where solidifying conditions are likely before reap. Summer precipitation can cause parasitic and bacterial pervasions.
