Growing Cranberries in Cape Cod

What is not to love about the cranberry? The color is gorgeous. The fruit is tart but becomes deliciously sweet when cooked with sugar. The plant is indigenous to North America and has a rich history of uses, both culinary and medicinal. Harvested in October and November, Thanksgiving is the cranberry’s time to shine.


My fascination with cranberries started when I was growing up in Southeastern Massachusetts, home to the Ocean Spray cooperative. We had only to drive twenty-five miles east to find acres of cranberry bogs along the highway to the Cape. There, my mother would often stop at the old Ocean Spray Cranberry House to pick up an assortment of cranberry pastries.


The early New England settlers referred to the cranberry as a crane berry because of the resemblance of the fruit’s pink blossom to the head and bill of a Sandhill Crane. Thanks to Johnston’s Cranberry Marsh & Muskoka Lakes Winery for the photo.


Flowers, Berries, and Bogs

Cranberry fields are not very exciting to look at in the summer. It is more the idea of what is coming that is exciting.


By late summer, you can start to see the red berries among the green vines hugging the ground.


In September and October, the bogs are flooded for harvest — now that is a vision! All the ripe fruit floats to the surface and suddenly there is a sea of red on the horizon.

If you dissect a cranberry, you will see there are four interior chambers where the seeds are located. These chambers hold pockets of air that allow cranberries to float when the fields are flooded. The air pocket also causes berries to bounce. Good cranberries bounce and float; rotten ones do neither. I learned that the first day of Home Ec at Dartmouth Middle School where we were taught how to make cranberry jelly and biscuits.


Some cranberries are white. I read that when you freeze or cook them they turn red as the pigment, anthocyanin, is released.


Horticulturally, cranberry vines are perennials; some vines have been growing for over one hundred years. Cranberry bogs consist of different layers of soil. The first layer is a naturally occurring clay base. It keeps the ground watertight. Next, is a layer of gravel for drainage, followed by a layer of a spongy, acidic soil known as peat, and finally, a top layer of sand.

The Harvest

Originally, cranberries were picked by hand. In the 1890s wooden scoops with built-in screens were invented and replaced hand-picking. My friend, Kendra, has a marvelous collection of these harvest implements.


Later, in the 1920s, a “walk behind” mechanical harvester was invented which is still used today for the ten percent of cranberries that are “dry-harvested.” These are the perfect cranberries, the ones that are packaged for baking.

In 1960 a wet harvesting machine was invented. This machine crawls over the flooded fields and dislodges berries from their vines allowing them to float where they are then corralled and vacuumed by farmers. Ninety percent of cranberries are harvested in this way. These berries are used for juices, dried cranberries, and canned sauces.

About a foot of water is piped into the bog for this process. Water is also piped in before a winter freeze to protect the vines from cold weather. As warm weather arrives, growers drain the winter flood, the vines come out of dormancy, and a new growing season begins.


These next photos were taken by Minda Bradley whose family farms cranberries in Kingston, MA.




Cranberry plants were traded by early colonists in exchange for goods from Europe. Sailors ate the berries, high in vitamin C, while crossing the sea to prevent scurvy. The plants were eventually transplanted to Europe, but the soil conditions were not the same, resulting in a different acid level and flavor. Lingonberry or English moss berry are examples of the European version of cranberries.

Ocean Spray Cranberries

Grower-owned Ocean Spray is a cooperative of over 700 farming families across North America who grow over 60% of the world’s cranberries. The cooperative was started in the 1930s in Wareham, MA. It is not uncommon to see one of these signs nestled on the side of the road on Cape Cod indicating the grower is part of the Ocean Spray cooperative. Finding one of these signs is akin to finding an old covered bridge in the countryside. They are special.


Perhaps now you will have a better understanding of what this message means when you see it on a bag of Ocean Spray cranberries.

I picked a cranberry vine from a field on the Cape so I could admire the gorgeous berries after I left New England.


In 1980, there was a shortage of cranberries, and the Ocean Spray cranberry growers consortium changed the amount of cranberries in a bag from one pound to 12 ounces. This is good to know if you are using old recipes that call for “one bag of cranberries.”  Know, too, that a heaping cup of whole berries weighs 4 ounces. Thus, a 12-ounce bag has about 3½ cups of berries.

  1. Judy, I loved reading about how cranberries got their name, how they are grown, and how they were/are harvested. Thank you!! Recipes look yummy, too. Have a wonderful Thanksgiving!!

  2. Judy, thank you for another blog that “ripens” my heart for the season. And, the blog is always so interesting. Thanksgiving blessings to all, especially that beautiful new grandchild. Now you know why they are called Grand!

  3. Judy
    I love your blog and read it eagerly – particularly this one that focuses on our neighborhood-
    So Dartmouth. Is Mrs Walker who made the pie Jane Walker, married to Bob Walker? If so, they are our neighbors in the summer. They built a house near us in Birchfield.

    Anyway have a very happy thanksgiving.

    1. Yes! Their daughter, Tish, was part of our gang of friends who played together once all the summer folk left for the winter. We played in every square inch of Bay View and Birchfield, including the huge cornfields in front of the Walker’s stately home.
      It was so much fun to figure out that author and Bay View neighbor, Erin McHugh and I were making the same pie for Thanksgiving. Please show Mrs. Walker my post if you get a chance. Happy Thanksgiving to you and yours. See you in the Spring! xo Judy

  4. Judy, what a magnificent article! I didn’t know I wanted to know so much about cranberries until you wrote it and I read it. Thank you. Happy Thanksgiving! You are a treasure. XOXOXO

  5. I loved reading about cranberries. Our family has Nantucket Cranberry Pie from Aunt Connie, who was brought up on the Cape. It is the same pie! I’ve never seen the recipe elsewhere before. Connie took it to every family Thanksgiving for years and while a few of us had the recipe, we never made it when she was coming as she was sure to bring it and loved getting the kudos for it. You other recipe are also inviting and I am planning on making the relish.
    Many thanks for taking the time to write such an interesting blog.

    1. Jan, that is so funny. Nantucket Cranberry Pie from Aunt Connie. Wow! We need to find the origin of this recipe. I just Googled Ocean Spray’s website and there is nothing similar there. Maybe it was in the newspaper years ago and lots of people saw it there. Thanks so much for sharing that!

  6. You’ve taught me some interesting things about cranberries, Judy! Never heard the thing about the name before. Also, didn’t know the white ones will turn red when cooked! Must experiment one day 🙂
    I have baked three apple-cranberry cakes in three weeks – just love having that on hand for a not-too-sweet snack, suitable pretty much any time of day. Or night. I tried adding pumpkin puree to a couple of cakes also, and got a very dense but still tasty result – texture of a boiled pudding, I think. Even with the losses to critters who will not be named, I have So Much Pumpkin from my garden this year! Anything I can possible add pumpkin puree to, will probably experience that modification at some point this winter.
    Thanks for the fun post!

    1. Quinn, thanks for all the comments. My husband and I were out on a walk and as your string of comments came in, I read each them out loud to him. We both enjoyed the notes. He was like, and how do you know her? I told him how we’d never met, in person, but that we read each other’s blog and we converse online. It makes the world smaller. I’m going to look for your cranberry cake recipe.eel certain you posted it last year. Keep on writing and keeping like beautiful and simple. Happy Thanksgiving!

      1. Oh, Judy, I do hope you will make the cranberry apple mosaic cake, because you are such a good cook you will probably improve it and then share the improvements with ME!

  7. I’m coming back to read this again more slowly so I don’t miss anything. This morning is a hit-the-ground-running kind of day. I will say that until I was grown my only exposure to cranberries was canned jellied cranberry sauce. “Cranberry sauce in the shape of a can”~~quote from Ernest Saves Christmas. Thankfully since then my horizons have broadened. And thanks for the heads up about the change in bag sizes. I just discovered that boxed cake mix has also shrunk. Pooh on the food industry. Oh….and Happy Thanksgiving!

    1. Thank you! You were one of the nice people to come out MDK’s introduction of my blog to the masses last year. I am so grateful for the online conversation we have begun. I probably would have been one of those people Ernest was talking about if I hadn’t learned to make cranberry jelly in home ec. I hope you try this recipe. I’ve got all of the ingredients out now to make a batch. You will end up with about 10 tasting spoons in the sink by the time you are through! Happy Thanksgiving!
