Soil & Growing Conditions

Water: Water regularly; feed with high-potassium liquid fertiliser once the first fruit sets (RHS)

Soil pH range

5.5 8

Span reflects genuine variation between the cited authorities, not a single agreed figure.

Growth Stages

Stage	BBCH	Notes
Sowing and germination	0	Sow indoors from late winter to early spring in seed compost, covered with a fine layer of vermiculite (RHS). Start seedlings indoors and do not transplant outside until night temperatures reliably reach 55F/13C (NC State Extension).
Vegetative growth	3	Pinch out growing tips at around 20cm to encourage a bushier plant (RHS). Grow on in full sun in rich, moist, well-drained soil (RHS; NC State Extension).
Flowering and fruit set	6	Feed with a high-potassium liquid fertiliser once the first fruit sets (RHS).
Harvest	8	Fruit is harvested summer and fall once fully coloured -- green through orange, red, white, brown, yellow or purple depending on variety (RHS; NC State Extension).

Harvest & Storage

When to pick: Fruit ripens from green through orange, red, white, brown, yellow or purple depending on variety, and is typically harvested in summer and fall once fully coloured (RHS; NC State Extension).

1. NC State Extension Gardener Plant Toolbox - Capsicum chinense (Carolina Reaper, Habanero, Habanero Pepper, Habanero Type Pepper)

   Native to Bolivia, northern Brazil and Peru. USDA hardiness zones 10a-11b. Plant out only once nighttime temperatures reach at least 55F. Thrives in heat, tolerates drought (though prolonged drought reduces fruit quality). Full sun (6+ hrs). Soil pH acid (<6.0) to alkaline (>8.0), clay/loam/sand/high organic matter, rich moist well-drained. Spacing 12in-3ft. Height 1-2.5ft, width 1-2ft. Start seedlings indoors, transplant at 55F+ nights. Common pests: aphids, whiteflies, cutworms, pepper maggots, Colorado potato beetles. Diseases: Verticillium wilt, mosaic virus (unspecified strain). Fruit is a non-pulpy berry with high capsaicin content, harvested summer and fall in gold, yellow, orange, purple, red or white.

2. Royal Horticultural Society - Capsicum chinense Habanero Group

   Very hot chilli peppers from the Amazon region, fruit 2-6cm long ripening from green to orange, red, white, brown, yellow or purple. Grow in loam or sand (acid/alkaline/neutral), moist but well-drained or well-drained, full sun, south/west-facing, sheltered. Hardiness H1C (5-10C min) -- best grown indoors on a sunny windowsill or in a greenhouse, or outside only after frost risk passes. Height 0.5-1m, spread 0.1-0.5m. Time to maturity 1 year. Sow indoors late winter to early spring; pinch out growing tips at 20cm to encourage bushiness. Water regularly, feed with high-potassium liquid fertiliser once first fruit sets. Susceptible to glasshouse red spider mite, whitefly, aphids, slugs, snails, and grey mould. Irritant if eaten; causes skin/eye irritation -- wear protective equipment when handling. Family Solanaceae.
