Arbutus unedo is probably one of the most beautiful ornamental plants that are cultivated in our gardens and on the balcony. The strong green colored foliage, the creamy-white umbels of flowers and the orange-red fruits with the warty skin make it particularly attractive. The natural occurrence of this exotic is the Mediterranean region, where it even thrives at altitudes of over 3,000 meters, where a relatively harsh climate sometimes prevails.

Strawberry trees also grow in colder regions

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 foliage and the trunk will be damaged.

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

Overwinter strawberry trees in the garden

Winter temperatures are only tolerable for strawberry trees in the wine-growing regions of Germany. But here, too, 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 dryness.

Overwinter potted plants

If you don't want to take any risks, you can overwinter Arbutus unedo indoors. In the winter quarters there should be a permanent temperature between five and ten degrees. Ideal are:

  • an unheated stairwell
  • the garage
  • a bright basement room
  • a greenhouse that is heated in severe frosts.

Only water the strawberry tree in sips during the winter months. The substrate should not dry out completely but should never feel wet. There is no fertilization at all during this time.

In the spring, carefully get Arbutus unedo used 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 sunburned, the foliage should only be exposed to the sun in the morning or evening hours in the first few weeks.
  • Gradually water a little more and fertilize every three weeks from May.

tips

Strawberry trees are extremely robust. In the natural home of the exotic forest fires are always raging. Even if all life seems to have been wiped out, it can be observed after a short time how Arbutus unedo will sprout again and within a few years will regain its old size.
