Blueberries are a valuable addition to fruit tree guilds in permaculture systems. Positioned in the shrub layer, they benefit from the shade and protection of larger trees while providing ground-level diversity. Their flowers attract pollinators, and their roots help with moisture retention, enhancing the overall health and productivity of the guild. Their nutrient-dense berries offer a reliable food source, complementing the fruit production of the larger trees.

Northern highbush blueberries are best suited for cooler climates, thriving in USDA zones 4-7. These plants require well-drained, acidic soil (pH 4.5-5.5) and full sun for optimal fruit production. Blueberries benefit from mulch to retain moisture, prevent weeds, and protect shallow roots. Consistent watering is essential, especially during fruiting. Blueberries are self-fertile but cross-pollination increases the overall yield, improves the size and quality of the berries, and leads to a more abundant harvest. Add organic compost or sulfur to the soil to maintain its acidity. Regular pruning encourages healthy growth and more abundant fruiting.
