🍎 Blueberry
Vaccinium corymbosum / V. angustifolium
fruits perennial bush
☀️ Sun
full sun
💧 Water
evenly moist; shallow roots dry out quickly — mulch essential
🗺️ Zones
3–8 (highbush), 2–7 (lowbush)
🪴 Soil Type
acidic, well-drained, high organic matter (peat, pine bark)
🧪 Soil pH
4.0–5.5 (strongly acidic)
📏 Spacing
4-5 ft apart, 8-10 ft between rows (bush; multiple varieties for cross-pollination)
📅 Days to Maturity
3-4 years (from planting); begins bearing 2-3 years after establishment
🍴 Edible Parts
🍽️ ["Fruit"]
🤝 Companions (8)
🤝 Evergreen shrubs (rhododendron, azalea, camellia)
Share identical acidic soil requirements; create beneficial microclimate and windbreak
🤝 Pine / Conifer trees (nearby)
Falling needles naturally acidify soil and provide ideal mulch; mycorrhizal fungi shared
Low groundcover suppresses weeds without competing; tolerates acidic soil; attracts pollinators
🤝 Thyme / Oregano / Marjoram
Low-growing herbs tolerate acidic soil; attract pollinators; oregano repels blueberry maggot fly
🤝 Cranberry / Lingonberry
Identical soil pH and moisture needs; complementary groundcover; shared pollinators like bumblebees
Dynamic accumulator mines potassium (critical for blueberry fruiting); chop-and-drop mulch acidifies slowly
Low-growing nitrogen fixer; tolerates acidic soil; feeds blueberries through root-zone nitrogen transfer
🤝 Lupine
Acid-tolerant nitrogen fixer; tall flowers attract bumblebees (primary blueberry pollinators)
⚠️ Keep Apart (4)
⚠️ Brassicas (cabbage family)
Require alkaline soil (pH 6.5+); soil pH conflict — cannot satisfy both; brassicas deplete nutrients blueberries need
⚠️ Nightshades (tomato, potato, pepper)
Prefer neutral-to-alkaline soil; verticillium wilt risk; compete for potassium
⚠️ Walnut trees (black walnut)
Juglone toxicity — blueberries highly sensitive; causes wilting and death even at root-zone edge
⚠️ Grasses (lawn / turf)
Competition for water and nutrients at shallow root zone; grass clippings raise pH
💊 Medicinal Uses
Contains exceptionally high anthocyanins (delphinidin, malvidin) and pterostilbene with neuroprotective, anti-aging, and cognitive-enhancing properties. Clinically studied for memory enhancement, cardiovascular health, and blood sugar regulation. Traditional Native American remedy for digestive health and as a general tonic. Blueberry anthocyanins cross the blood-brain barrier.
