2. You can dehydrate whole blueberries as easily and as well as halved blueberries, but halving cuts down on the dehydration time quite a bit (about 40%), so I suggest first halving all the blueberries.
3. Lay your halved blueberries cut side down on the dehydrator trays, leaving at least half a blueberry’s thickness sized space between each berry (approx. 1/16 of an inch).
4. Place your first filled dehydrator rack in your open dehydrator.
5. As you continue to fill dehydrator racks with berries, stack the completed racks on top of each other.
6. When you are out of blueberries to stack on racks, put the cover on your dehydrator and turn it on!
After you “harvest” your blueberries, allow them to cool a little before storing them in resealable bags, mason jars, or cannisters to preserve their freshness.
