Blueberries are a favorite treat of summer. If you have access to fresh blueberries that you particularly enjoy, you can actually save the seeds and try growing some blueberries of your own. Harvesting and storing your own blueberry seeds is not a complicated task, and the rewards last all season; from seeing that first seedling sprout up, to enjoying the fresh taste of blueberries at harvest time.
Put water in the blender until it is half full.
Put 1/2 cup of blueberries into the blender. The berries can be fresh or frozen.
Put the lid on the blender and put on the "Blend" setting for 45 seconds. When the blueberries are blended, the pulp and poor-quality seeds will rise to the top. The viable seeds that can be used in planting will sink to the bottom of the blender.
Shut the blender off and wait 30 seconds for the usable seeds to sink.
Add more water to the blender until it is full. Wait 15 seconds to allow more seeds to sink if need be. Dump half of the water out, and add more. When dumping, try not to dislodge the good seeds that are at the bottom of the blender. Continue this process until the water in the blender is clear and you have the pile of good seeds at the bottom.
Place paper towels along the bottom of the colander, and pour the rest of the water and good seeds out of the blender into the colander. Allow the liquid to drain.
Place the seeds onto a dry paper towel and try to spread them out. Allow the seeds to dry.
Put the dry seeds into a paper or wax paper envelope and store them in the freezer until you wish to use them.
