Organic Growing Tips
Acidify soil with pine needle mulch, composted bark, or sulphur chips before planting.
Net plants with fine mesh as berries begin to ripen to protect from birds.
Plant comfrey nearby to act as a mineral accumulator that feeds blueberries through chop-and-drop.
Test soil pH annually; blueberries are highly sensitive and will fail in alkaline soil.
