Growing Peppers Indoors – Guidelines & Tips

Growing peppers indoors can be a fun and rewarding experience! While it may present some unique challenges, with the right knowledge and preparation, you can easily enjoy a bountiful harvest of pungent or mild peppers inside your own home.

Getting Started

The first step in growing peppers indoors is selecting the variety you want to grow. Some popular peppers with good indoor growing characteristics include bell peppers, jalapeno, cayenne, Hungarian wax, and banana peppers. Pick a container with bottom drainage holes and a removable tray to catch any water runoff.

Potting Soil & Fertilizer

Make sure to use potting soil that is amended with organic matter like compost, manure, or peat. For maximum fertility, use a liquid fertilizer with a balanced ratio of nitrogen, phosphorus, and potassium (N-P-K); follow the label directions for proper application. If using organic fertilizer, such as bone meal or blood meal, be sure to mix it into the soil before planting.

Light & Temperature

Light and temperature are essential for peppers to thrive inside. Place your potted pepper plants near a south-facing window or set up a grow light to provide 8 to 10 hours of bright but indirect sunlight each day.

Temperature must remain consistently warm, between 65 and 75℉. If it gets too cold or too hot, the plants may stop producing peppers.

Water & Pest Control

Peppers grown indoors need watering regularly to keep the soil slightly damp, but not saturated. Water the soil directly with room-temperature water; avoid splashing the leaves or flowers as this may cause rot.

If pests become an issue, be proactive with natural, organic repellents. Neem oil can be used to help fend off aphids, mites, and other soft-bodied bugs that may be attracted to indoor plants.


Once the peppers start ripening, usually in late summer or early autumn, monitor them closely and harvest them as soon as they’re ready. Avoid over-watering plants at this stage, as too much water can reduce the number of peppers produced. You can easily enjoy your homegrown peppers raw in salads or cooked for a delicious meal.


Growing peppers indoors is a great way to enjoy homegrown vegetables all year round. As long as you give your plants the right environment and plenty of TLC, you can reap a steady harvest of your very own peppers. Happy harvesting!
