Hardy or sensitive to frost?

How much cold can the strawberry tree tolerate?

Arbutus unedo is not as sensitive to cold as gardeners often assume. However, the following applies: the older the plants are, the lower temperatures they can withstand. However, these should never fall below minus fifteen degrees, because then the leaves and the trunk will be damaged.

Even if the above-ground part of the tree dies in a very harsh winter, the underground tuber usually survives and sprouts again the next year. However, it will take some time for the plant to regain its size and splendor.

Hibernate strawberry trees in the garden

Only in the wine-growing regions of Germany are the winter temperatures tolerable for strawberry trees. But even here you should preferably place the Mediterranean plant near a house wall and, in addition to good care, ensure adequate winter protection. Recommended are:

• A thick layer of foliage around the Tree grate.
• A cover made of air-permeable Plant fleece or jute.
• Water the tree occasionally to prevent frost drought.

Hibernate potted plants

If you don't want to take any chances, you can overwinter Arbutus unedo indoors. A permanent temperature between five and ten degrees should prevail in the winter quarters. Ideal are:

• an unheated staircase
• the garage
• a bright basement room
• a greenhouse that is heated in case of severe frost.

Water the strawberry tree only in sips during the winter months. The substrate should not dry out completely but under no circumstances should feel wet. There is no fertilization at all during this time.

In the spring you can carefully accustom Arbutus unedo to the changed conditions on the balcony or terrace.

• At first, only place the plant in a warm corner during the day.
• So that the strawberry tree does not get sunburn, the leaves should only be exposed to the sun in the morning or evening hours in the first few weeks.
• Gradually water a little more and from May every three weeks fertilize.
