Cranberry planting areas

Cranberries are mainly grown in the southern hemisphere and are adapted to cool climates. The soil needs acidic and peat characteristics. After such a long period of research, the most suitable area for cranberry growth is 45-60° north latitude, spanning southern Canada, northern United States, northern China, and some central European countries. In other words, only these areas are most suitable for growing cranberries. Latitude requirements and soil are key. Planting in the remaining areas will be affected by different factors.

In addition, the weather at 45° south latitude is also suitable for growing cranberries. However, there are only Chile, Argentina and New Zealand around the span of 45° south latitude. The land is extremely scarce. Chile is now the third largest producer of cranberries. Planting country. In the far north of China, adjacent to Russia, in Fuyuan City, Heilongjiang Province, more than 4,000 acres of cranberries are planted, which has been developed in recent years.
