Why is my blueberry not fruiting well and how do I keep the plants healthy?

Poor blueberry fruiting usually comes down to a few things, soil pH that is not acidic enough, a variety whose chilling requirement is not met in your climate, weak pollination, young plant age, or wrong pruning. Blueberry needs distinctly acidic conditions, and if the medium drifts toward neutral or alkaline the plants struggle and barely fruit, so regular pH monitoring and correction is essential. Cross-pollination between two or more varieties usually improves berry set and size, and bees help, so do not rely on a single variety. Annual pruning to remove old, weak wood encourages productive young shoots. It is a demanding crop. Check your medium pH and variety chilling match, and confirm the right varieties, pollination plan and pruning for your conditions with your KVK or a horticulture university.
