Pistachio trees are only partially hardy

Pistachio trees are native to desert regions where it is very sunny, hot and dry. At night, it can be cold and sensitive, so that older trees survive well for a short time even at minus temperatures.

Protect pistachio trees outdoors from the cold

Pistachio trees should only be planted outside in areas where it is very sunny and warm. The soil should be well dry. If the humidity is too high, the roots rot.

Winter temperatures should not fall below minus ten degrees. Then the branches and roots freeze.

To be on the safe side, a pistachio tree should be protected from the cold outdoors in winter.

Winter protection for the pistachio tree

Cover the earth with a foil or jute sacks that protect the floor from heat loss. Mulch blankets are not as good as they provide the soil with too many nutrients.

Protect the branches with straw or other suitable materials. But make sure that the tree continues to get enough air.

Do not water the pistachio tree in winter. The tree needs virtually no moisture during the rest period.

Winterize potted plants

If you pull your pistachio trees in the tub, you should put them outside in the summer. Only then is a pollination of the flowers by the wind possible.

In winter place the tubs in a frost-free place. Temperatures around ten degrees are sufficient. Since the tree loses its leaves during the rest period, it does not need as much light as in summer.

Bring the pistachio trees into the house at the latest when the outside temperatures approach freezing.

Suitable wintering opportunities for pistachio trees

Care during the winter

Over the winter, let the soil almost dry out in the tub and only pour very little water if the potting soil appears completely dry.

Check the tree for pest infestation from time to time.
