Safety

People: The capsaicin in peppers can cause significant skin and eye irritation if handled without care.
Pets: Chili peppers contain capsaicin, which can cause gastrointestinal irritation and discomfort if ingested by cats or dogs.
Children: Keep hot peppers away from small children as the capsaicin can cause intense pain if rubbed into eyes or skin.
Contact allergens: Handling hot peppers can cause a burning sensation on the skin due to capsaicin oil.
Airborne allergens: Inhaling dust from dried peppers or fumes from cooking can irritate the respiratory tract.
Edibility: Always wash peppers thoroughly to remove any potential pesticide residues before consumption.

Common problems

Aphids — Small insects that cluster on new growth and suck plant sap.
Blossom End Rot — A dark, sunken spot on the bottom of the fruit caused by calcium deficiency or uneven watering.
Bacterial Spot — Causes small, dark, water soaked spots on leaves and fruit.

Growing it

Propagation: seed
When to plant: spring
Overwintering: Bring containers indoors before the first frost and place them in a sunny window. Keep the soil slightly moist but not soggy during the winter months.
In containers: Peppers grow very well in containers, provided you use a pot at least 12 inches wide with drainage holes.

Seed Starting

Sow seeds in a seed starting mix 8 to 10 weeks before the last frost.
Keep the soil warm and moist until germination occurs.
Provide bright light once seedlings emerge.
Transplant outdoors only after all danger of frost has passed.

Planting aromatic herbs nearby can help mask the scent of peppers from hungry pests.

Grows well with

Basil — Basil is thought to improve the flavor and growth of peppers.
Marigold — Marigolds help deter harmful nematodes and other pests.
Onion — Onions help repel common pests that bother pepper plants.

Keep away from

Fennel — Fennel can inhibit the growth of many garden vegetables.
