How Do Cranberries Grow?

Cranberries, native to the swamplands of North America, grow on vertical branches, called uprights, which extend from long, trailing vines that form a dense mat during the growth cycle. The fruits form from the blossoms that populate the uprights and the runners.

For commercially produced cranberries, the growth process when starting new plants can take more than a year to complete. Cranberry vines require a cold dormant cycle during the winter months, which begins when temperatures fall to 45 degrees Fahrenheit or lower. Cranberry bogs are typically flooded at the start of the dormant cycle to protect the vines from harsh winter temperatures. After the vines reach full blossom, it takes approximately 80 days until the cranberries are ready for harvest.
