How Are Blueberries Grown?
Have you ever wondered how blueberries are grown and harvested? Here’s everything you need to know about California Grown blueberries!
Are blueberries native to California?
Blueberries are native to California. Indigenous people referred to them as “star berries.” They used the berries for food and all parts of the plant for medicinal purposes.
When Europeans first came to North America, legend says that the Native Americans shared blueberries with the settlers to help them survive the bitter winter.
Are wild blueberries different from store-bought berries?
Wild blueberries have been grown for over 10,000 years, but blueberries weren’t cultivated until the beginning of the 20th century. It’s simple to discern the difference between the two different varieties. Wild, or lowbush, blueberries are much smaller. Farmed, or highbush, blueberries are larger and have a higher water content. Most of the blueberries sold at your local grocer are highbush blueberries.
Where do blueberries grow in California?
Blueberries grow throughout the Golden State, but most commercial farms are in California’s San Joaquin Valley. Blueberries require acidic, well-drained soil to thrive. Farmers typically have to amend the soil before planting.
How are blueberries grown in California?
Blueberries grow on tall bushes planted in a series of long rows. Farmers must wait 3-4 years after planting until the bush is mature and ready to be harvested. Mature bushes continue to produce fruit for up to 30 years! Fun fact: Blueberry bushes can grow over 12 feet tall, but most top out at around six feet.
Do blueberry bushes need to be pruned?
After harvest, growers prune their blueberry bushes to encourage new growth and productivity. The best time to prune is in winter when the bushes are dormant.
Do blueberries need bees to produce fruit?
Blueberry bushes are self-pollinating, but having bee boxes nearby can increase yields.
When are blueberries harvested?
Blueberry harvest runs from April through June in California. Because blueberries are allowed to vine-ripen, they are harvested multiple times throughout the season.
How do farmers know when blueberries are ready to be harvested?
The first sign that a blueberry is ripe is the color. A ripe berry will have a consistent, deep blue hue from stem to crown. When you gently shake the plant, it will fall off easily. The second way to tell when a blueberry is ripe is by taste. A ripe blueberry should be sweet and bursting with flavor.
How are blueberries harvested?
Fresh blueberries are carefully hand harvested to protect the fragile fruit.
Blueberries that will be packaged and sold frozen, freeze-dried, or used for jams and jellies are mechanically harvested. Machines are used to shake each bush, causing the ripe berries to fall into a catching frame. The berries are collected and stored in large bins until they are whisked away to a packaging plant.
What happens after blueberries are harvested?
After harvest, blueberries are transported to a packaging facility. Here, they are carefully sorted, cleaned and packaged. Finally, the blueberries are in cold storage and shipped to your local grocer.
How to choose blueberries at the grocery store
It’s easy to tell if blueberries are at peak freshness. Look for dark purple to almost black berries. A whitish “bloom” is perfectly normal. In fact, it’s a sign of freshness. Berries should be plump and firm with no wrinkles.
How should you store blueberries?
Blueberries typically last for about a week when properly refrigerated (although our friend Jerry James Stone swears that this hack keeps blueberries fresh for up to three weeks). If frozen, blueberries will last for up to a year.
