Your blueberry plants are growing well but not producing many berries, that's a bit frustrating. I think one thing to look at is the soil pH, blueberries need it to be pretty acidic, around 4.5 to 5.5. If your soil is too alkaline, that could be limiting production. You might consider getting a soil test to check the pH and nutrient levels. As for fertilizer, a balanced acidic fertilizer can help, but make sure it's not too high in nitrogen or it can promote leaf growth over fruiting. Also, are your plants getting enough water and sunlight, blueberries need consistent moisture and full sun to produce well.
