Will the olive tree survive outside during the winter in Poland?

NO. The olive tree will die without heat and sunlight. It's best to move it to a greenhouse, but that doesn't guarantee it will survive either

The olive tree, depending on its age, is able to survive the winter in our conditions.
It is very important to prepare them for wintering.

Adequate hydration Before winter. Lagging and pruning in late autumn.

If it's a mild winter, it should hold up. You can still put agro non-woven fabric (white) as it is not large in size

The olive tree in Poland can be grown as a pot plant. In summer and warm spring as much as possible on the balcony or terrace. In winter at home in the right conditions

The olive tree can withstand the winter in Poland, but it will need proper care. The olive is sensitive to freezing, especially after last year's pruning and pruning. A good solution is regular watering, special agents for protection and a frost-resistant cover for the winter. However, it will be best to grow the olive tree only indoors or in a more mild climate.

NO

Not because it needs warmth

Unfortunately, without light and warmth, the tree will not develop

NO

If it is a cold winter, there is little chance of survival outside without proper protection

So it will last because we now have a changeable climate in Poland and I recommend planting it in the ground

Olive wood is not resistant to frost and winter in Poland is too harsh for this plant. The olive tree requires a temperature not lower than 0°C and will not withstand temperatures below -10°C. Therefore, if you want to grow it, you must provide it with the right conditions, e.g. in a heated greenhouse or a warm room during the winter. In Poland, the olive tree will not survive the winter outdoors.
