Bell pepper bell-pepper Bell pepper (Capsicum annuum) is a warm-season crop grown as an annual in Nordic climates. Plants prefer steady warmth and strong light. In most of Sweden, they perform best under cover (greenhouse, tunnel, or a warm balcony) but can succeed outdoors in the warmest microclimates. Fruits color from green to yellow, orange, red, or purple depending on variety. Thick-walled, blocky types need more heat; smaller or early cultivars ripen faster. Support with stakes or a string system to prevent branches from snapping under fruit weight. Growing conditions LightFull sun, warm and sheltered; 8–10+ hours of direct light is ideal. Greenhouse or a south-facing wall in cooler regions. Soil typeFertile, well-drained, moisture-retentive loam rich in organic matter. Amend with mature compost; avoid compacted or waterlogged soils. Water requirementEven moisture; keep consistently damp but not soggy. Mulch to reduce evaporation. Avoid large dry-wet swings to prevent blossom end rot. Nutrient requirementModerate nitrogen, high potassium and calcium. Use a balanced start, then switch to a K-rich feed during flowering and fruiting. Back to plant list
