Growing Peppers Indoors – Guidelines & Tips

Are you looking for a fun and rewarding project to do indoors? Growing peppers indoors is a great way to bring more flavor and diversity to your cooking while sprucing up your interior decor. Though pepper plants require some specialized care, the end result is worth it.

1. Choose the Right Variety of Pepper Plant

The majority of pepper plants are perennial, meaning they’ll keep coming back year after year. However, you’ll need to select a variety that is well-suited to an indoor environment.

Sweet peppers: Sweet peppers come in a variety of colors, sizes, and shapes. Some of the most popular varieties for indoor growing include bell peppers as well as varieties such as ‘Clermont’ and ‘Gourmet’.

Hot peppers: If you’re feeling adventurous, try growing hot peppers indoors. Cayenne and jalapeno peppers are two of the most popular varieties. They tend to thrive indoors and have a short growth cycle.

2. Set Up a Warm and Well-Lit Space

Your pepper plants will need plenty of sunshine, steady temperatures, and good ventilation to thrive. Try to place them in a south- or southwest-facing window. You may need to supplement the light by investing in a grow light.

Also, make sure your pepper plants won’t be exposed to sub-freezing temperatures. Remember, if you’re growing indoors, your plants will need supplemental heat during the winter months.

3. Plant in Fertile and Well-Draining Soil

In order for your pepper plants to flourish, you’ll need to use fertile and well-draining soil. Use a standard potting soil mix, and incorporate some compost for a nutrient-rich blend.

For best results, it’s also a good idea to invest in a pH test kit. The ideal pH for pepper plants is 6.5–7.0. If the soil is significantly more acidic or alkaline, you may need to add some lime or sulfur to adjust the pH balance.

4. Water and Fertilize Consistently

For best results, keep your pepper plants consistently moist but not overly saturated. Aim for about one inch of water per week. Fertilize your plants about once a month using a diluted liquid fertilizer.

Keep an eye out for signs of nutrient deficiency, such as yellowing leaves. This could be a sign that your plants need additional fertilizer.

5. Harvesting & Storing

It’s recommended that you wait until the peppers have developed a deep and vibrant color before harvesting. You can store your freshly-picked peppers in the refrigerator or dry them for longer-term storage.


Growing peppers indoors is a rewarding and flavorful project. Just make sure you choose the right variety of pepper plant, create a bright and warm environment, plant in fertile soil, water and fertilize regularly, and harvest at the right time. With a bit of effort, your pepper plants will bring great flavor and beauty to your home.
