When to plant
Plant in early spring. Blueberries produce heavily from years 3–4 onward and can produce for 50+ years. Plant at least two different varieties for cross-pollination (significantly increases yield). They are one of the most rewarding long-term garden investments.
Soil & site
Blueberries have very specific soil requirements: pH 4.5–5.5 (quite acidic). Most garden soils need acidification with elemental sulfur or acidic compost (like pine bark). Rich in organic matter. Perfect drainage — blueberries don't tolerate standing water. Test and adjust soil pH 6–12 months before planting.
Feeding
Use an acid-forming fertilizer specifically formulated for blueberries (ammonium sulfate, or a "berry fertilizer"). Never use lime. Feed in early spring when buds swell. A second light application in late spring after fruiting. Over-feeding produces vigorous growth but fewer berries.
Common problems
Mummy berry disease (shrivelled berries — rake up affected berries, apply mulch to prevent spore germination). Birds are the biggest harvesting pest — net bushes when fruit begins to colour. Fruit fly (spotted wing drosophila) in late-season crops. Iron chlorosis (yellowing leaves with green veins) from pH too high — acidify soil.
When to harvest
Blueberries are ready when the entire berry is uniformly deep blue or blue-purple (no pink or red tinges), soft to the touch, and comes off the cluster with the lightest nudge. Berries that require any force aren't ripe. Taste-test is the best guide — ripe blueberries are sweet with no bitterness.
How to harvest
Gently roll ripe berries off the cluster with your thumb, letting them fall into your palm or a bucket. Unripe berries resist this motion — leave them. Productive bushes need picking every 5–7 days during the 4–6 week harvest window. In the morning, when berries are cool, they're firmest and easiest to handle without crushing.
Storage & use
Don't wash until ready to eat. Fresh blueberries keep in the refrigerator for 1–2 weeks. Freeze on a baking sheet first (freeze individual berries, not a clump), then transfer to bags for up to a year. Frozen blueberries retain all their antioxidants.
Companion planting
Blueberries need acidic soil. Thyme as a groundcover helps retain moisture and deter pests.
