Growing directions
Blueberries require acidic soil with a pH of 4.5–5.5; amend with elemental sulfur and use acidic mulch such as pine bark or wood chips 3–4 in deep. Plant at least two cultivars for cross-pollination and better fruit set. Prune out old canes older than 6 years at the base each late winter to stimulate productive new wood. Harvest when berries turn deep blue and detach with minimal resistance, typically 7–10 days after color change.
