Do Cranberries Grow in Water?

Last Updated on October 11, 2023

Cranberries are not grown in water, but flooding bogs with water is used during the cranberry growing season and ‘wet harvesting.’

Let’s find out how cranberries are grown and harvested, along with some other cool cranberry facts.

How do cranberries grow?

Cranberries (Vaccinium macrocarpon) grow in wetlands on low-running vines in dry beds layered with sand, peat, gravel and clay. These beds, called “bogs,” were originally made by glacial deposits.

Today commercial growers construct cranberry beds in upland areas too.

Are cranberries grown in water?

Ok, I still feel your hesitation… 😊

I know what you are about to ask… 

“Are you sure that cranberries do not grow in the water? What about all those Ocean Spray commercials with farmers standing deep in the water and cranberries floating around them? Is it a lie?”

Do you remember this 2006 Ocean Spray commercial reminding that cranberries are good for you?

I wouldn’t call commercials too deceiving because water indeed plays an important role in commercial cranberry growing.

Flooding bogs with water is used a few times during a year in order 

  • To protect cranberry plants from the winter cold
  • To control pests
  • To remove fallen leaves
  • To harvest cranberry fruit using the “wet method”. 

The Ocean Spray commercial was shot during “wet harvesting”. 

This leads us to another question:

How are cranberries harvested?  

There are two methods of cranberry harvesting: “wet” and “dry”.

The wet method for harvesting cranberries is also called flood harvesting. 

It occurs after the berries turn red, which usually starts at the end of September and lasts till November.

The night before cranberries are harvested, the bog is flooded with about 18 inches of water. Cranberries float to the surface because each cranberry fruit has 4 air pockets. 

Then the berries are cut from the vine by machine, gathered together, and sucked into a truck that will take them to the plant. They will be used for making processed food, like cranberry juice or jams.

Approximately 90 per cent of the cranberry crop is harvested this way.

Fresh cranberries you buy for Thanksgiving in the supermarket are “dry harvested”.

How cranberries got their name

The name “cranberry” came from German kraanbere (English translation – craneberry), because the plant’s blossoms resemble the head and bill of a crane. 

European settlers that came to America called cranberries “craneberries”. 

 I do not know about other European countries, but in Ukraine cranberries are called “журавлина”, which translates as craneberry too, and in Russia, they are called “клюква” which can be translated as “beakberries”.
