Site & Soil Prep
- Sun: Full sun (8+ hours) for best heat and yield
- Soil: Loose, fertile, and well-drained; target pH 6.0–6.8
- Amend: Mix in 2–3 in (5–7.5 cm) of finished compost plus a light application of a balanced organic fertilizer at planting; avoid heavy nitrogen up front (delays fruiting)
- Rotation: Do not follow tomatoes, peppers, eggplant, or potatoes the prior year
Watering (Consistency is Everything)
- Keep soil evenly moist—aim for ~1–1½ in (2.5–4 cm) water/week including rain
- Water deeply and less often to encourage strong roots; avoid waterlogging
- Container plants dry faster—check daily in hot weather and water when top 1 in (2.5 cm) is dry
- Mulch after soils warm to reduce evaporation and prevent swings that cause blossom drop
Feeding (Light but Regular)
- At transplant: Light, balanced feed mixed into the planting hole
- Vegetative stage: Modest nitrogen; over-feeding = lush leaves, late fruit
- Budding/fruiting: Shift toward K-forward nutrition (still balanced overall) every 10–14 days (containers: every 7–10 days at lower strength)
- Calcium/Magnesium: Supplement if your water is soft to reduce blossom-end rot–like symptoms
Temperature & Season Management
- Ideal: Days 75–90°F (24–32°C); nights 60–75°F (16–24°C)
- Stress thresholds: Flower set suffers <60°F (16°C) and >95°F (35°C)
- Heat waves: Use 30–40% shade cloth midday; water in the morning to reduce stress
- Cool snaps: Cover with row cover at night; keep root zone warm with dark mulch or fabric
Training, Pruning & Support
- Staking/Caging: Recommended—heavy fruit and winds can snap branches
- Pruning: Light tipping early can increase branching; avoid heavy pruning on mature plants
- Sanitation: Remove damaged leaves/branches to improve airflow and reduce disease pressure
Mulch & Weed Control
- Apply 2–3 in (5–7.5 cm) organic mulch once the soil is warm
- Suppresses weeds, evens soil moisture, and protects fruit from soil splash
Pollination
- Peppers are self-fertile; gentle airflow and pollinators improve set
- Avoid broad-spectrum insecticides during bloom; encourage beneficials
Pests & Diseases (IPM Quick Guide)
Scout weekly. Treat early and choose the least-disruptive option first.
- Aphids, thrips, spider mites, whiteflies: Blast with water; use insecticidal soap or horticultural oil; increase airflow and avoid plant stress
- Pepper weevil/fruit borers (region-dependent): Remove infested fruit; keep area clean; consider fine mesh exclusion
- Slugs/snails: Hand-pick; traps; keep mulch pulled back from stems
- Bacterial leaf spot, anthracnose: Rotate annually; water at soil level; remove infected tissue; sanitize tools
- Viruses: Do not smoke/handle tobacco around plants; wash hands; rogue symptomatic plants promptly
Common Physiological Issues
- Blossom drop: Heat/cold stress, drought, or high nitrogen—stabilize environment and moisture
- Sunscald on fruit: Provide better canopy or temporary shade in extreme sun
- “BER-like” spots: Irregular watering or low Ca/Mg—correct moisture and supplement if needed
- Leggy growth: Insufficient light or excess nitrogen—adjust both
Harvest & Handling (Super-Hot Safety)
- Harvest when fruit is fully colored and firm; flavor and heat peak at full maturity
- Wear gloves (and consider eye protection). Do not touch eyes/face.
- Use clean, sharp snips to avoid branch damage
- Post-harvest: Refrigerate unwashed fruit in breathable bag up to 1–2 weeks; for long-term, dry at low heat (110–125°F / 43–52°C) until brittle, or freeze whole fruit
Containers (Performance Tips)
- Volume: Minimum 5 gal (19 L); 7–10 gal (26–38 L) ideal
- Medium: High-quality potting mix; add perlite/pumice for drainage
- Fertility: Regular, dilute feed; flush with clear water monthly to avoid salt buildup
- Support: Stake/cage from the start to avoid disturbing roots later
Overwintering (Perennializing C. chinense)
In frost-free or protected conditions, super hots can live multiple years.
- Before first frost, prune lightly (remove flowers/immature fruit)
- Pot up if in ground; keep at ≥60°F (16°C) with bright light
- Water sparingly in winter—just enough to prevent wilt
- In spring, up-pot/refresh mix, resume feeding, and re-acclimate outdoors
Seed Saving — Super Hot Peppers (C. chinense)
Isolation & Purity
- Isolation distance: For home seed use, keep different pepper varieties 50–150 ft (15–45 m) apart with windbreaks; for higher purity, 300+ ft (90+ m).
- Physical controls: For maximum purity, bag a few branches before bloom or cage entire plants with insect netting; introduce pollinators inside cages if needed.
- Species note: C. chinense readily crosses with other C. chinense and can occasionally cross with C. annuum; isolate accordingly.
Parent Selection
4. Select true-to-type, disease-free plants with excellent flavor, yield, pod shape, and heat profile.
5. Rogue off-types early (flowering through fruit set).
Harvest & Processing
6. Harvest fully ripe pods (deep final color).
7. Wet extraction (recommended):
- Split pods and scrape seeds into a jar with a little water
- Optional 12–24 hr fermentation loosens pulp; do not over-ferment (can reduce viability)
- Rinse in a fine sieve until seeds are clean and sink
- Drying: Spread in a single layer on a non-stick surface; dry with steady airflow and shade at ≤95°F (35°C) until snaps, not bends (7–14 days depending on humidity).
Storage & Viability
9. Label with variety, species, and year.
10. Store cool, dark, and dry: ~40°F (4–5°C) with low humidity in airtight containers.
11. Viability: 3–5 years typical under good storage; test yearly with a 10-seed germination check (aim ≥75%).
Safety
12. Wear gloves when processing seeds from super hots; dust is potent. Clean tools and surfaces thoroughly.
Troubleshooting (Quick Reference)
- Stalled plants early season → Soil too cold; use dark mulch or fabric, delay feeding heavy N
- Flowers but no fruit → Temps outside ideal range; uneven moisture; excess N; improve pollination airflow
- Leaves cupping or bronzing → Mites or thrips; inspect undersides; treat promptly with soap/oil and increase humidity/airflow
- Bitter/off flavors → Drought stress or nutrient imbalance late; maintain even moisture and balanced feeding
