Growing Blueberries - When and How to Grow Blueberries In Your Garden

Updated on January 18, 2017

Fresh Blueberries

Blueberries have gained a lot of favor recently as a health food that is high in antioxidants. Nonetheless, they are a delicious treat and like most fruits, they always taste better when fresh from the garden. But how do you grow your own blueberries?

Blueberries grow on bushes that bear fruit for several years, so it can be a worthwhile investment of your time, money and efforts. You should also know that it takes a couple of years for blueberries to start producing depending on the variety you plant, unlike it's well-known companion strawberries.

Spotlight On Blueberries

Types of Blueberry Bushes and Their Hardy Zone

The first step in growing blueberries is to identify the type of blueberry bush that will grow best in your area. You need to make sure that the bush is suited to your hardiness zone. There are four basic target varieties of blueberries.

Highbush: This is the most common commercially grown type of bush and can grow over six feet tall. It produces larger fruit than some other varieties, is hardy up to zone 4, and can be grown in much of the south as well.

Half High Blueberries: Not quite as tall as the highbush, but are hardy as far north as zone 3. Somewhat smaller fruit than highbush as well.

Lowbush Blueberries: These are not as erect as the other varieties, growing up to 18 inches in height. They spread in growth through runners, acting like a groundcover and not as much as bushes. Hardy to zone 3, but does not do well in the south, these are much more a northern variety.

Rabbiteye blueberries: These are better for the south and are native to parts of the Southeast. These are the tallest variety of all and are hardy in zones 7 through 9.

Preparing the Soil to Grow Blueberries

Blueberries are related to azaleas and rhododendrons, and like very acidic soil similar to their plant cousins. The best soil pH would be about 4.5. They require some soil preparation, with a good first step mixing in a few bushels of peat moss. After that, test the soil again, and add sulfur to get the pH to the targeted range. It is best to use a soil gauge to check the proper soil levels.

Most blueberry plants have fairly shallow roots and since they will be in place for years the preparation of the soil is critical. The best is a loamy mix, consisting of 4-7% organic matter like compost. If the combination of acidity and drainage is not feasible you may want to consider raised garden beds.

Planting Blueberries Together

When to Plant Blueberry Bushes

How many bushes should you plant? That, of course, will vary with the size of the family you want to feed, but four to six bushes can service an average family. The spacing should be five to six feet for the large varieties, and maybe three feet for the lowbush blueberries.

Wait to plant until after the last frost date. When you are planting, dig a hole about 18 inches deep and 18 inches in diameter, which will accommodate plants grown in containers quite easily. As you pack the soil in around the root ball, cover the stem slightly. This will encourage runner development.

Care of Blueberry Bushes

These bushes need at least one or two inches of water per week. Keep in mind that tap water can affect the pH and mineral content of the soil so when possible use rainwater. To help retain water and reduce watering needs a two-to-four inch layer of organic mulch is recommended. This will naturally help suppress the weeds as well.

Use a fertilizer that won't increase the pH of the soil. It's also best to avoid concentrated fertilizers, since it is easy to damage the roots of your bushes if these aren't properly diluted. Organic fertilizers like soybean or cottonseed meal work very well, or you might use an organic azalea fertilizer as they are formulated to maintain a lower soil pH.

Blueberry bushes will likely not blossom until their second year, and many suggest removing any blossoms the first year to encourage stronger root systems and improve the long term yields of the bushes.

Controlling BIrds and Other Pests

Birds are the most common pest problem with blueberries. The simplest solution to controlling birds is bird netting. Just remember that when you put up bird netting, the birds can land on the ground and walk under it unless you secure it to the ground around the bushes. Sometimes you may have problems with rabbits or other small rodents. An effective solution there is to put a small chicken wire fence around your blueberries.

Another solution is to use a motion activated sprinkler.

Pruning Blueberry Bushes

You probably won't need to prune your blueberry bushes for the first three years. Again, removing blossoms in the first year to stimulate strong new growth is encouraged. When the time comes to prune, do it in in the early spring on dormant plants. Thin out the dead and weak growth, and be sure to open up the middle of the plant to allow light and air to the center of the plant. Remember the blossoms bud out of two year old or older growth. Finally, when you have fruit set, like any fruit tree or bush, it's important to thin it out as if too many berries are on the bush they will not develop adequately.

Harvesting Blueberries

Harvesting blueberries can be done by shaking the bush. Place a container, screen or towel under the bush. When they are ripe, they will simply fall out into your chosen vessel. Or, if you are harvesting wild blueberries, it is more than likely you will want to hand-pick the berries from the bush.

There is nothing like a handful of fresh berries to go plop on your breakfast cereal, bowl of ice cream or just plain pop them in your mouth! Blueberries are an excellent food for lower your cholesterol.

      Removing the flowers early in the life of the bush is a normal practice and should increase the strength of your bush and a higher yield for the future. Good Luck!

      Very enjoyable and informative article. I actually got a small crop this year from two blueberry plants in containers on the porch. Over the past two weeks there have been about one quart of berries ripen. It was great picking a handful each day then storing them in the freezer for use in recipes.

      I have 4 or 5 year old blueberry bushes that every year set on small, hard, green berries. Tissues berries never ripen into fruit. Last year, the berries did actually turn blue, but they never grew large enough to pickl. Any ideas on what I need to do?

      Thanks!

      What do you think of the little giant blueberries? If you haven't heard of them they are offered at http://littlegiantblueberry.com. I was wondering if you think this is a good deal or if $10 for three plants is so cheap that they have to be crap?

      If you have trouble with rodents eating them, just use repellents. I use DeFence for my garden and now don’t have any problems with rabbits or deer. And it’s cheap too. I got mine for $12 at my local lawn & garden store. I’m getting my next bottle online though. You get 10% off if you sign up for the e-newsletter.

      Here's the stuff I’m talking about:

      If there's no recent tender growth most likely you've not had any damage from a frost, not a hard freeze. Just wait a little and see, or try scratching the branch to see if there is still fresh growth under the surface.

      I have planted 3 different blueberry bushes and planted them in 1/2 wine barrels. I followed the soil recommendations, but the companies instructions recommended cutting back the initial branches after planting to encourage root browth. I did that after 3 days in the soil, but we have had a frost since planting and I am worried they have died. How do I tell?

      Nice article. It's good to see encouragement for growing fruit. One of my recent blog entries suggested blueberries: http://www.smallkitchengarden.net/small-kitchen-ga... I'm going to add a link so my readers can learn more about it from your hub page.

      Thanks for th eadditonal info John,

      My littlest one and I planted a highbush seedling this past winter and almost immediately it flowered and now has set five little fruit. I have warned everyone not to touch them and that I will destribute them when they ripen.....or else!
