Cranberry cranberry American cranberry is a low, evergreen, vine-like shrub forming runners that root and produce vertical ‘uprights’ bearing flowers and fruit. It thrives in cool climates with acidic, organic soils that stay evenly moist. Unlike commercial flooded bog production, home gardens should grow cranberries in raised, contained, acid beds or large planters. Aim for pH 4.0–5.5, high organic matter (peat/sphagnum + sharp sand), and consistent moisture with good aeration. Contain the bed to keep acidity, and mulch with pine needles or coarse peat to suppress weeds and conserve moisture. Plants spread 1–2 m but stay only 10–20 cm tall. Flowers in early summer; berries ripen deep red in autumn and store or freeze well. Growing conditions LightFull sun to light partial shade; 6–8 hours of sun gives best fruiting. Soil typeMoist, acidic, organic-rich medium (peat/sphagnum with sand), well-drained yet evenly wet; avoid lime and high-carbonate water. Water requirementHigh. Keep consistently moist, never waterlogged in winter freeze. Use rainwater if possible. Nutrient requirementLow. Light feeding only; excessive nitrogen causes rank runners and poor fruiting.
