While it is more common to grow blueberry plants from small seedlings purchased at your local nursery, you can also grow them from seeds. High and low bush varieties of blueberry seeds can be planted in the same manner. Once the seeds grow and mature over the winter, you can transplant the plants outdoors in the spring, just after the last frost. Plant more seeds than your desired amount of plants, just in case some do not thrive.
Gather your seeds. You may be able to purchase them or you can collect them from existing blueberries. If they are from a package, read the label carefully as you may need to refrigerate them for a couple months to break dormancy, but otherwise you can proceed to step 3.
Freeze your fresh blueberries for 3 months to break dormancy. Then, mix in ¾ a cup of water in a blender or grinder and grind away on high for about 10 seconds (you can also use a bowl and pedestal to mash). Remove the blueberries from the blender/grinder and allow them to sit for at least 10 minutes. The seeds will start to sink. Add some water and allow the seeds to sink and the pulp to rise. Keep repeating this until you can easily scoop away the pulp and remove the seeds. Allow the seeds to dry in a single layer on a paper towel.
Use a planting tray--or similar--that is at least three inches deep. Fill with sphagnum moss that is moist. Sow the seeds on the surface and then cover with a thin layer of more moss. Keep the soil slightly moist and cover with newspaper. Place the tray in an area that is between 60 and 70 degrees F.
Wait for your seeds to germinate. Generally, it should take about a month, at which time, you should place them in a sunny area of your home, such as a south facing window. Again, keep the soil moist.
Allow your new seedlings to grow a couple inches and then transplant them in individual pots. You can use general potting soil or make your own with equal parts of peat, sand and soil.
Keep the blueberry plants in a sunny area of your home and in a couple weeks fertilize with a balanced liquid fertilizer. Follow manufacturer directions except only use half the recommended dosing amount.
