Blueberry Picking Tips, Canning Directions and Facts about Blueberries

Crops are great this year, all over – no late frost!

Blueberries are one of the easiest fruit to prepare and serve. There’s no peeling, pitting, coring or cutting. They have few natural pests, (other than birds), so pesticides are generally unnecessary! This year’s crop is fantastic (see related news story), thanks both to the weather and to more farms planting more blueberry bushes due to increased consumer demand over the past few years as more studies proclaim the anti-oxidant and other health properties of blueberries.

If you are looking for information about a similar berry, the saskatoon (also called the June berry or Serviceberry) see this page about saskatoons.

Picking tips:

Select plump, full blueberries with a light gray-blue color. A berry with any hint of red isn’t fully ripened. White and green colored blueberries will not ripen after they are picked; while blueberries that have already turned purple, red or blue-ish usually DO ripen after they are picked (if they are kept at room temperature to ripen).

Since blueberries hang on the bushes in bunches a but like grapes do, the easiest and fastest way to pick them is hold your bucket under them in one hand and with your other hand, cup a ripe bunch and gently rub them with your fingers. The ripe berries will drop into your bucket, while the unripe ones will remain attached to the bush.

When the bushes are at peak, I can easily pick 2 gallons per hour (if I’m not being distracted by the kids and the sun isn’t too hot!). A newbie might do 1 gallon per hour.and at the beginning or end of the season it takes more time as the berries are not as plentiful nor concentrated in clusters.

Tips for storing blueberries after harvesting:

  • Once picked, don’t place the berries, still warm from the sun, in a closed bag or container. Leave the container open so moisture doesn’t form in the container.
  • Don’t wash berries until just before using, to prevent berries from becoming mushy.
  • Chill berries soon after picking to increase shelf life. Store your fresh blueberries in the refrigerator as soon as you get them home, without washing them, in a covered bowl or storage container. If refrigerated, fresh-picked blueberries will keep 10 to 14 days.
  • Freeze berries in freezer containers without washing to keep the skins from toughening. Place berries one layer deep. Freeze, then pour the frozen berries into freezer containers. Because unwashed blueberries freeze individually, they can be easily poured from containers in desired amounts. Remember both frozen and fresh berries should be rinsed and drained just before serving. Just before using, wash the berries in cold water.

Blueberry Measurements and Conversions

Blueberry Facts

  • Blueberries are ranked No. 1 in antioxidant activity compared with 40 other commercially available fruits and vegetables. That means a serving of blueberries has more of the antioxidant power you need to fight aging, cancer and heart disease.
  • Put this in your pipe! Indians in the Northwest Territory smoked wild blueberries to preserve them for the winter. (Bet you didn’t know that!)
  • Want to grow your own blueberries? Here’s an article about how to: Growing Blueberries in the Home Garden, HYG-1422-98
  • Weights and measures: 1 cup of blueberries normally weighs about 143 grams, which about 1/3 of a pound, so 1 pound of blueberries is almost 3 cup’s worth. Of course, this can vary considerably based on the variety, weather conditions and degree of ripeness. Typically, many recipes call for 3 to 4 cups of blueberries for a 9 inch pie.
  • Nutrition and miscellaneous facts: 1 cup (143 grams) of blueberries is 84 calories (technically, kcal). Blueberries contain no cholesterol or fat and are also low in calories. Blueberries are high in dietary fiber, Vitamin A and niacin. They contain iron and other trace minerals and are a fair source of Vitamin C. Blueberries have a diverse range of micronutrients, with notably high levels (relative to respective Dietary Reference Intakes) of the essential dietary mineral manganese, vitamin B6, vitamin C, vitamin K and dietary fiber (table below). One serving provides a relatively low glycemic load score of 4 out of 100 per day.
    Especially in wild species, blueberries contain anthocyanins, other antioxidant pigments and various phytochemicals possibly having a role in reducing risks of some diseases, including inflammation and different cancers. Blueberries may have anti-disease effects, too. Researchers have shown that blueberry anthocyanins, proanthocyanidins, resveratrol, flavonols, and tannins inhibit mechanisms of cancer cell development and inflammation in vitro. Similar to red grape, some blueberry species contain in their skins significant levels of resveratrol, a phytochemical with increasing evidence as an anti-cancer compound.

If you have trouble with blueberries settling to the bottom of muffins and blueberry breads, try one or more of these tips:

  • Coat them with flour before adding to the batter. Just gently shake the blueberries in a bag (plastic or paper) with 1/2 cup of flour, then dump them mix in a sieve to remove excess flour.
  • It may just be that your batter is too thin. try making the batter a little thicker!
  • Fill the muffin cups or baking pan up to 1/4 full with batter (which hasn’t had blueberries added to it yet); then stir the blueberries into the remaining batter, and continue to fill the muffin cups or bread pan. The blueberries will start off higher in the mix!

Blueberry Questions and Answers

Q. How do I remove blueberry stains on clothes?

Rinse fresh stains immediately in cold water. Soak any more difficult stains in a solution of 1 Tbsp. vinegar in 1 quart (or 1 liter) of warm water.
Tide Laundry Detergent recommends soaking the stained article for up to 30 minutes in 1 gallon of water with 1/2 scoop dry Tide with Bleach or 1/2 measuring ladle of liquid Tide with bleach. in a plastic bucket. Keep the clothing submerged by placing a white towel on top of it. Discard the soaking solution prior to laundering.

Q. We would like to purchase some blueberry plants and plant them this November. Where can we purchase some nice size plants ?

A. There are 4 options:
1. Local nursery
2. Mail order
3. Big box store (Home Depot, Lowes, Wal-Mart)
4. Free shoots dug from a neighbors plants

Being shallow rooted, blueberry bushes are constantly sending shoots off the side roots. These well started planted shoots can be dug with a generous portion of root and replanted. Just be sure: get plenty of root, mulch and fertilize annually and water sufficiently, especially the first year. Replant in late fall or early winter. Cut off about 1/3 of the shoot so the root system matches the top. Find a friend with a blueberry patch and help yourself!
I’ve been very disappointed with the blueberry bushes I ordered from mail order nurseries; the plants were tiny (6 inches or so). The ones at my local Wal-Mart usually looked pretty pathetic. In my experience, Lowes and Home Depot usually have big (2 ft tall) healthy plants that are suited to your local climate. Beware mislabeled plants – I’ve purchased plants from big box stores which were not the variety on the label, although that was peaches and apples, not blueberries.

The local nurseries often have nice stock, but my local nursery’s prices were pretty high, unless I wait for an end of season sale.. I’ve been happy with the one’s at Lowe’s and Home Depot!

Q. My Mom always told me to put my freshly picked blueberries into a bowl of water. She said the ones that float have bugs in them or are bad. How can I tell if this is true?

A. That’s just an old wives’ tale. Some float because they are less dense, which may be due to a variety of causes, only rarely because a bug is inside. The only pest I’ve heard of getting inside a blueberry is the blueberry maggot, larvae of Spotted Wing Drosophila, which affects some plants in the north eastern US and parts of Canada.

Here are the methods to detect the presence of the pest in blueberries, according to the Ontario Ministry of Agriculture

Methods for Detecting Blueberry Maggot Larvae in Blueberry Fruit

Hot Water Test

  2. Nearly cover the berries with water.
  3. Bring berries and water to a frothy boil and boil for at least 1 minute.
  4. Empty berries into a 4-mesh-per-inch screen.
  5. Gently crush berries in screen with the back of a spoon.
  6. Rinse berries with cold running water and collect water and solids in a pan with a black bottom.
  7. Allow the debris to settle and Decant floating solids and most of the water.
  8. Repeat washing and Decanting until water is clear.
  9. White maggots will be visible against the black bottom of the pan.

Brown Sugar Test

Sugar concentration = 2 lbs (1 kg) brown sugar per 1.2 gallons (5 litres) of water.

  1. Place 1 litre (2 pints) of berries in a 4-litre (1 gallon) container.
  2. Gently crush berries in container.
  3. Add sugar concentrate to 3 cm above crushed berries.
  4. Agitate crushed berries in sugar solution.
  5. Allow maggots to float to surface.

My Blueberries Are Sour: How To Sweeten Sour Blueberries

When you pop fresh-picked blueberries into your mouth expecting sweet, delicious fruit, then sour blueberry fruit is a great disappointment. Unless you’ve selected tart berry cultivars, altering your care and harvest of blueberries may solve the problem. Read on to learn why blueberries are sour and what to do with sour blueberries.

What Makes Blueberries Sour?

The first thing to do when garden blueberries are sour is to determine the characteristics of the cultivar you have chosen. With hundreds of types of blueberries available, the cultivar fruit taste can vary from tart to sweet. If your bushes are intended to produce tart or sour fruit, you may want to select new cultivars.

A common cause of sour blueberry fruit is over-production on a bush. If your bush is newly planted, you’ll get sweeter, bigger berries if you remove all blossoms for the first year or two to allow the root system to establish. Even mature blueberry bushes can over produce some years and, if left to their own devices, produce abundant but sour fruit. Keep your eye on buds and thin back when needed.

Let your berries ripen on the bush. It is not a good idea to pick berries early. Even if you can get sour blueberry fruit to soften by storing them beside apples or bananas, they will not sweeten any further. If blueberries are sour when picked, they will remain so. You can’t sweeten sour blueberries once you take them from the bush.

Try eating a few berries before beginning your harvest and remember that all berries do not ripen simultaneously. Even in one cluster, some may be ripe and some unripe. Identify unripe berries by the reddish hue, but even solid blue berries need to stay on the bush for a few days before they develop true sweetness.

Waiting is a good way to sweeten sour blueberries. Blueberries can remain on the bush for 10 days after they begin to ripen, so don’t be in a hurry. The fruit size and sweetness increases very quickly as the end of the ripening process.

Ensuring that your blueberry plants are grown in acidic soil and keeping them fertilized annually will also help to sweeten the blueberries.

What to Do With Sour Berries

If you’ve already harvested your blueberry fruit, you may be asking what to do with sour berries that haven’t fully ripened. Placing the berries in a paper bag and storing in a cool place will allow the fruit to ripen. If you add an apple, banana or avocado to the bag, the berries ripen more quickly.

Keep in mind that this will soften immature berries, but it will not sweeten sour berries. If you want to cook with the berries, just add extra sugar or honey.

    Macerate Them

    Macerating—soaking or steeping in liquid and/or sweetener—is one of the easiest and fastest ways to doctor up sub-par berries.

Then let it all sit at room temperature for an hour (store in the fridge if waiting longer to eat). The berries will become saucy, taking on the aromatic flavors you added with the sugar. Serve with whipped cream or ice cream, and you’ve got a dessert that never fails to impress. Use juice instead of alcohol, and your morning yogurt will put those store-bought “fruit on the bottom” yogurt cups to shame.

    It’s science, or something: Adding sugar, eggs, and butter to anything makes it taste better. So it’s no surprise that muffins, cakes, and scones made with berries are greater than the sum of their parts. But there’s another reason that baking berries makes them taste better: Their flavors become concentrated when cooked, intensifying the sweet notes. Toss the fruit in a light dusting of flour before adding them to the batter so they become suspended in the baked good; otherwise, they’ll sink to the bottom in a big berry pile. Or, make a crisp, cobbler, or crumble. The buttery, crunchy topping is a perfect foil for sweetened, jammy, just-cooked berries.

    Sour Blackberries

    A gardener wrote in recently:

    “I have thornless blackberries bushes, but every year the berries are sour. What can i do to sweeten them up?”

    I don’t have personal experience with thornless berries, but in my research I found two common answers to this question.

    1) The berry bushes may be old and apparently there’s nothing to be done about it. Time to get new berries.

    2) It’s important to wait to harvest the berries until they are no longer shiny. They will have passed from the dark black, shiny stage into a duller black stage and should come right off the vine easily. They will be much softer at this stage as well.

    The second answer was most common in my search. As far as soil goes, here is an excerpt from Paul Vossen on Growing Blackberries in California:

    “Blackberries do best in well-drained sandy or loamy soils with a pH between 5.5 and 6.5. A good supply of organic matter in the soil improves aeration and drainage and increases water-holding capacity. You may apply organic matter during the summer or fall before you plant. … If you use manure, compost or another source of organic fertilizer, apply it in the late fall or early winter. Apply approximately 50 pounds …per 100 feet of row. If the plant lacks vigor, apply an additional 1 pound of ammonium nitrate per 100 feet of row at bloom or midsummer, just prior to an irrigation. ”

    Regarding irrigation, he says:

    “Blackberries require approximately 1 to 2 inches of water per week from mid-May through October. It is best to keep the plants moist at all times without soaking and rotting the roots. Blackberries do better if the entire row is kept moist.”

    Hopefully this information will help you with your blackberry problems. Keep us posted on your next harvest.

    Not every blueberry is created equal — there are a lot of varieties, with different flavor profiles.

    For tart, firm berries, go for the early-season Emeralds, says Manuel Jimenez, a University of California Cooperative Extension farm adviser in Tulare County, Calif. A softer and sweeter option is the Jewel. The Reveille has lots of sweetness, while Southmoons have “the best flavor and sweetness combination,” he says.

    Enjoying all of these varieties depends on selecting good ones. Look for full, rounded berries covered with the white, powdery coating called bloom. Avoid shriveled and leaky berries.

    At home, store them in the refrigerator, and do not wash them until just before using. They’ll keep in the refrigerator for five to seven days, or you can place them in sealed plastic bags in the freezer.

    “If you’re going to freeze berries, don’t wash them before freezing,” says Kingsburg, Calif., blueberry farmer Gayle Willems. If wet, the berries will stick together and get icy. They will keep in the freezer for up to a year, but like all other frozen foods, it’s best to eat them within a few months.

    Blueberries are known for their high levels of antioxidants, which help prevent cell damage. “Ounce for ounce, blueberries provide more antioxidants than any other fresh fruit or vegetable,” Dana Jacobi writes in her “12 Best Foods Cookbook.”

    To get the most health benefits from blueberries, eat them plain and uncooked. “Heat diminishes the benefits of the phytonutrients they contain,” Jacobi writes.

    For those compelled to tinker in the kitchen, the sweet-tart flavor of blueberries works well in sweet and savory dishes. A classic combination is blueberries, lemon and mascarpone cheese, which makes an easy topping for cookies. On the less sweet side, blueberries add a fruity punch to corn bread. And with thyme, shallots and lemon juice, these little berries are a great sauce for meats.

    Blueberry-mascarpone shortbread

    Prep: 10 minutes

    Makes: about 16 cookies

    This is a versatile formula for a quick dessert. Substitute sugar cookies for shortbread, and try different flavor combinations, such as blueberries and bits of candied ginger.

    8 ounces mascarpone cheese

    1/4 cup confectioners’ sugar

    1 teaspoon lemon zest, from about 2 lemons

    1/8 to 1/4 teaspoon fine-grained sea salt

    16 homemade or store-bought shortbread cookies, about 2 1/2 inches wide

    6 ounces blueberries

    Combine mascarpone, confectioners’ sugar and lemon zest in a bowl. Add 1/8 teaspoon sea salt; mix well. Taste and add more salt, if necessary. Spread mascarpone mixture on cookies; top with blueberries.

    Yay!!! It’s strawberry season! Strawberry season is the local kick off to a summer of great produce. Not much beats ripe, freshly picked strawberries. Everyone gets excited and a bit crazy during the first few days of the season. Demand is high and the berries are moving. In order to keep up with the craze, you’ll find that sometimes the berries are picked in haste. If you’re not picking your own, you might find a bit too many under ripe strawberries. Not so sweet and delicious.

    You know what else is not so sweet & delicious – the majority of strawberries I buy throughout the year at my local grocery stores. They look like big, bright, juicy berries – but when you taste them, well you don’t taste much 🙁

    The first thing I do when I bring berries home is remove them from their cartons, rinse them off and let them air dry. This way they’re ready to eat. This is also the time you should inspect for any bad berries that need to be tossed or badly bruised & overly ripe berries that need to be eaten right away.

    So what to do with those greenish-whitish sour strawberries. Easy. Chop up all your cleaned berries, throw them in a bowl and mix them up with some sugar. Cover and refrigerate for a few hours. The sugar and natural acidic juices from the strawberries mix and macerate/marinate the berries in sweetness. No need to make a simple syrup – the berry juices do it for you. This works best with a mixture of juicy ripe and not so ripe berries.

    That’s it. At times I feel silly stating what seems obvious to many. After having a conversation with an older woman at the grocery store today, I realized there are a lot of people who don’t know such little tricks.

    On another note, if the strawberry crop is abundant, buy up on it while it’s cheap. Strawberries freeze very well – even more so if you have a vacuum sealer.

    Okay, enough reading! Go out and get your fresh strawberries – the season doesn’t last too long!

    Thanks for stopping by! Hope you have a beautiful day : )
