Blueberry seeds require many of the same types of environmental conditions as other plants to germinate successfully. Having just the right temperature and water levels can make or break a successful germination, or sprouting of seeds prior to planting. Blueberry seeds are particularly picky about the conditions needed for germination. Because they are very small, for example, blueberry seeds need ample amounts of light.

Place the planter box on a table or other flat surface.
Cover the seeds with a very fine layer of moss, just until the seeds are covered. It’s important to give the seeds access to light to spark the germination process.
Sprinkle the blueberry seeds evenly on top of the moss. Spread the seeds with your fingers so there are about 10 seeds per square inch.
Spray the top of the moss with the water bottle until moist. Place the container in a room where the temperature is regulated at between 60 and 70 degrees Fahrenheit. It is not important to place the container in direct sunlight at this point, but it should receive at least partial sunlight.
Germinating blueberry seeds can increase the chances of a successful plant.
Line the bottom of the planter evenly with about 1 inch of finely ground sphagnum moss. Spray the moss with a spray bottle filled with water until the moss is moist, but not soaking wet.
Check to make sure the moss is moist every day, and spray with the water bottle to keep the moss moist.

Extract the seed by one of the following methods:
- Waring Blender (Kitchen Blender)
Place 3/4 cup of thawed berries in blender. Fill 3/4 full with water. Put on cap and run blender at high speed for 10-15 seconds. Allow to stand 5 minutes. Seed will sink to the bottom while pulp will stay suspended in the water. Very slowly pour off some of this pulp and add fresh water. Allow seed to settle again. Slowly pour off more pulpy water. Add more fresh water. Allow seed to settle. Keep repeating this cycle until all the pulp is removed and only blueberry seed remains in the bottom. Remove seed and spread on a paper towel to dry.
- Food Grinder
Grind 3/4 cup of thawed blueberries and place in quart jar. Wash inside of grinder into jar also. Fill to 3/4 full with water and cap. Shake vigorously for a few minutes. Allow to stand five minutes as above, and follow same procedure in pouring off the pulp.
- Mashing Berries In a Bowl Place 3/4 cup of thawed berries in a mixing bowl. Mash thoroughly with a pedestal. Place in a quart jar and follow same procedure as above.

Lowbush blueberries can be propagated quite easily from seed. The plants can then be set out in prepared rows, vacant areas in fields or as an ornamental ground cover plant for home landscaping. The best time to start seed is in January or February.

- Obtain seed from blueberries that have been frozen at least 90 days. This will break the seeds’ nest period. A small amount of seed will start quite a few seedlings.
