Cranberries grow on small shrubs and vines and the edible red fruits are an annual staple in Thanksgiving and Christmas dinners. Despite being an unusual crop for home gardeners, you can harvest cranberries from your yard by growing them in containers or raised beds.

Cranberries are harvested in the cooler months of fall and are used in sauces, jams, and juices, or dried. You want to harvest cranberries at their peak ripeness as unripe ones are less tart and the quality diminishes if they get overripe.

If you are growing cranberries and have questions about harvesting, this guide is here to help. It looks at the key signs that show a cranberry is ripe and reveals the best way to harvest cranberries at home for all your culinary needs.

Cranberries are unique fruiting shrubs due to their specific demands for moist and acidic soil types, conditions not readily seen in many backyards. For this reason, many choose to grow cranberries in container gardens or raised beds to create the ideal environment. The best time to plant cranberries comes in spring and it should take 2-3 years from planting to the first harvest of cranberries.

The months to harvest cranberries run from September to early November. When they mature will depend on your location and the growing conditions, but some signs indicate when cranberries are ripe - in the shape of the color, firmness, and seed color.

‘The color of the cranberries should be a deep red,’ advises Tammy Sons, an experienced horticulturist and founder of TN Nursery. ‘The cranberries should also be firm and glossy. The seed inside a ripe cranberry will be brown.’

Another quirky way to tell the firmness of cranberries is to give them a ‘bounce test’ to assess the ripeness. This involves gently dropping a cranberry to see if it slightly bounces. A ripe cranberry will bounce as it has an internal air pocket.

Cranberries can be eaten fresh or used in the kitchen and Katie Brines from Stark Bro’s recommends adjusting when you harvest cranberries depending on their intended use.

‘When using the berries for sauce, jelly or juice pick them slightly under-ripe,’ claims Katie. ‘However, if you are going to eat the berries fresh then plan on picking after a frost so the berries will be soft and sweet.’

Commercial cranberry farmers tend to grow the crop in bogs and harvest the fruits in one of two ways. They either have machines that can remove the cranberries from the vines, or they flood the bogs with water. The air pockets inside cranberries mean that ripe fruits float in the flooded bogs and can be collected.

These methods are fine for large-scale cranberry harvesting, but growers at home with just a few plants are advised to use the dry picking method to harvest cranberries. It is advisable to dry pick on a dry day, as moisture on the fruits from rain, frost, or dew can make removing the fruits from the vine more difficult.

Run your hands, or a berry picker, through the vines to loosen the berries from the vine. Place a harvesting basket or container under the plant to collect the cranberries as they detach from the plant. A stylish and lightweight harvesting hod like this one on Amazon is well suited to being held under plants to harvest the fruits into.

Gently and methodically work your way through the vines to get all the fruits. Ripe cranberries should come away easily, so do not pull too hard when picking as it can be a harvesting mistake that can damage the vines.

FAQs

How do you ripen cranberries after picking them?

Cranberries can be encouraged to ripen after harvesting by putting them in a sealed paper bag. The fruits will give off ethylene and speed up the ripening process. Adding an apple or banana to the bag can further accelerate ripening.

Can you eat raw cranberries?

Cranberries can be eaten raw, though have a very sour and bitter taste. They are often cooked with sugar added to combat that sharp taste. Freshly harvested cranberries can be kept for up to two months in a refrigerator or can be frozen to store for longer.

How do you dry cranberries?

Cranberries can be dried in an oven by laying them in a single layer on a baking sheet and placing them in an oven set at its lowest setting for up to eight hours.


Cranberries are just one of many crops you can cultivate to grow your own Christmas dinner. If you have a vegetable garden and want homegrown crops for festive plates, plant vegetables such as potatoes, carrots, broccoli, and Brussels sprouts in summer to be ready to harvest come December.
