Fans of the blueberry know how pricey they can be at the supermarket. Growing them at home is much less expensive and a rewarding hobby. Although most blueberry bushes that you see in the nurseries and gardening centers were propagated by cuttings, it is possible to grow the lowbush varieties, wild blueberries, from seed. Grab a handful of berries from the nearest bush or ask a neighbor for a few from her plant. Start the process in January or February.
Freeze the blueberries for 90 days.
Remove the blueberries from the freezer and remove the seeds from the blueberries. There are several methods commonly used for this extraction, the easiest of which is to mash them in a bowl. Pour the mashed berries into a 1-quart jar, fill the jar to within one-fourth of the top with water, cap it, and shake the jar vigorously for three minutes. Allow the jar to stand for five minutes. The seeds will sink to the bottom and the pulp will rise to the top. Carefully pour off the pulp, add fresh water, allow the seeds to settle again and pour off the remaining pulp. Remove the seeds and lay them on a paper towel to dry.
Fill the seeding flat with pre-moistened sphagnum peat moss. Sprinkle the blueberry seeds over the surface of the moss and cover with a thin layer of moss. Use the misting bottle to moisten the top layer of moss and to water the seeds whenever the moss begins to dry.
Cover the flat with newspapers and place it in an area that remains between 60 to 70 degrees F. The blueberry seeds should sprout within one month.
Remove the newspaper when the seeds have germinated and place the flat in a sunny area. Use the plant misting bottle to keep them moist.
Transplant the seedlings when they are 3 inches tall. Mix together equal parts of peat moss, sand and potting soil. Moisten it well and pour it into the planting pots. Carefully remove the seedlings from the flat and plant them into the pots. Place them in a sunny location and keep the soil moist.
Fertilize the blueberry seedlings three weeks after transplanting with starter fertilizer at half the rate suggested on the package.
Transplant the blueberry seedlings, after all danger of frost has passed, into their permanent location.
