Can I ask where we can grow oranges in Shandong?

Shandong Province is not suitable for planting orange trees in open fields.

Orange trees are evergreen fruit trees. The lowest temperature in winter is below minus 5°C, and the branches are prone to frost damage. In Shandong, the lowest temperature in winter often drops below minus 10°C. Orange trees cannot survive the winter safely in the open field, and it is difficult to guarantee yield.

From a technical perspective, it is feasible to plant orange trees in late-winter greenhouses. Whether it is economically feasible deserves careful investigation and analysis. However, if you take the path of picking, sightseeing, and traveling, it is feasible to plant orange trees in a greenhouse.
