WINTER CHILL NEEDED
~800–1200 hrs
POLLINATION

Growing it
Zones 2-7. A low, running bog plant that needs constantly moist, very acidic, high-organic soil - a lined sunken bed works. Not flooded like a commercial bog.
Will you get enough chill?
Cranberry needs roughly 800–1200 hours between 32 and 45 °F over winter to break dormancy evenly. Check your area with the chill hours calculator. Low-chill breeding has pushed many varieties well below the figure here, so read the plant tag.
Chill and pollination are given at the fruit-type level; specific cultivars can differ. Values are typical ranges for home-garden planning.
