Another question is why aren’t my blueberries turning blue?
The most likely reason for this is blueberries, the ones that don’t ripen are the kind of berries. Some strains require longer periods of cold winter temperatures to properly fruit. If you live in a warmer region, the plants may not have had a sufficiently long chilling period. Late winter or spring frosts can then kill them.
Second, can you grow a blueberry bush from a blueberry?
Blueberries propagate reliably well from fresh seed, although the resulting bush can do so not very similar to the mother plant. The seeds do not require any pre-treatment to germinate successfully, but chilling increases their germination rate and contributes to a successful outcome.

How to make blueberries sweeter?
Sprinkle 1 tbsp. Gradually pour the sugar over the berries and taste as you taste to prevent over-sweetening. Honey is sweeter than sugar, so add honey one teaspoon at a time. If using yogurt or heavy cream to sweeten the berries, add about 1/4 cup of yogurt or heavy cream to the bowl.
Are blueberries self-pollinating?
