How to grow blueberries from seeds

Growing blueberries from seed is easy. Some Blueberry species like lowbush blueberry and highbush blueberry serve a dual purpose in landscaping, they serve as both an ornamental ground cover and edible crop. The lowbush blueberry and highbush blueberry grow best within USDA plant hardiness zones eight and below, where they will start producing fruit during their 2nd year in the ground.

Furthermore, growing blueberry plant from seed is reliable when you’re working with fresh seed, even though the resulting shrub may not closely resemble the parent plant. The blueberry plant seeds require no pretreatment to successfully germinate, although chilling them will enhance their germination rate and also help ensure a successful outcome.

How to Prepare Blueberry Plant Seeds

You can gather the blueberries in summer after they have ripened to a solid, bluish-black color and the flesh has yields to slight pressure. You can also collect some berries from your favorite blueberry bush in other to increase the likelihood of locating viable, intact seeds.

You have to place the blueberries in a sealable plastic bag. You have to store them in the freezer for about 3 months to cold stratify the seeds, this will actually help to fulfill their dormancy requirement and also help prompt germination.

You can easily take out the blueberries from the freezer after the cold stratification period has ended. Then place the bag on the counter for about 1 to 2 hours or until the blueberries have thawed to room temperature.

Get a blender and fill it with three-quarters full of fresh water and then pour in 3/4 cup of blueberries. Secure the lid. Run the blender for about ten to fifteen minutes to macerate the berries.

Then pour the blueberry pulp into a very large mixing bowl and let it stand for about 5 minutes. You have to scoop out and discard the pulp that floats to the surface. You need to carefully pour off the excess water. Then add fresh water and allow it stand for another 5 minutes.

You have to pour the contents of the bowl through a fine sieve or wire mesh colander. Then collect the tiny, reddish brown blueberry seeds from the sieve. You can spread them out to dry on a sheet of newspaper.

How to Germinate Blueberry Plant Seeds

You have to fill in your 12-inch nursery pots with a moistened mixture of equal parts; milled peat, coarse sand and loam. Then sprinkle a pinch of the blueberry plant seeds across the surface of the soil. Spread a very scant layer of milled peat over the blueberry plant seeds so they are barely covered.

You have to place the nursery pots outdoors inside a lightly shaded cold frame. You can cover each of the pot with a sheet of newspaper. You can warm the pots to about sixty and seventy degrees Fahrenheit with a germination mat if daytime temperatures actually stay below 60 F. 

Ensure you maintain constant moisture in the top inch of the soil while the blueberry plant seeds germinate. Make sure you use a plant mister or a spray bottle to water because a watering can or other strong water stream can dislodge the tiny blueberry seeds.

Watch the blueberry seed germination for about one month. Then remove the newspaper and the germination mat after the blueberry seedlings emerge. You need to crack open the cold frame to help acclimate the blueberry seedlings to normal outdoor conditions.

Make sure you thin the blueberry seedlings to 2 per pot once they grow to about two inches. You can keep the strongest, most vigorous of the seedlings and then remove the weaker ones. Snip off the unwanted blueberry seedlings at soil-level with a small sharp scissors.

You can easily move the nursery pots to a sheltered spot outdoors with dappled shade. Make sure you water to a depth of 1 inch every week. You can transplant the blueberries plant to a sunny or lightly shaded bed with moist, acid soil in the following autumn.
