How to Grow Peppers in Pots (Sweet and Hot)

After tomatoes, peppers are the king of the container garden: compact, decorative (fruit turns from green to red, yellow or orange) and very productive in the sun. They work for both sweet peppers and hot chilies, and the care is virtually the same.

Fact	Peppers in pots
Pot size	4-5 gallons per plant
Light	6+ h of sun and warmth
Watering	Regular, no waterlogging
Feeding	Potassium-rich from flowering
Harvest	Green or ripened to color
Difficulty	Medium

Choose the variety

Sweet / Italian / frying: medium plants, very productive.
Hot (chili, jalapeño, cayenne): compact and perfect for pots, plus very decorative.
Mini / snack peppers: ideal for small balconies.

Pot and soil

At least 4-5 gallons per plant (the bigger, the more harvest).
Rich soil with compost and good drainage. Drainage holes essential.

Sun and temperature

Peppers love heat: they want 6+ hours of sun and warm temperatures. In cold or low light, the flowers drop without setting. A south- or west-facing balcony is ideal; don't move them outside until frost risk has passed.

Watering

Regular watering without waterlogging (like tomatoes, irregular watering causes blossom-end rot on the fruit):

When the top inch is dry; in summer, often daily.
Water the base, not the leaves, ideally in the morning.

Feeding

From flowering, feed every 1-2 weeks with a potassium-rich fertilizer (tomato ones work). Too much nitrogen gives lots of leaves and few peppers.

Tricks for more harvest

Pinch the first flower (the "crown flower") so the plant grows stronger before fruiting.
Stake it if the fruit gets heavy: the branches are brittle.
Pick green to stimulate more production, or let it ripen to color for more sweetness and vitamins.
