Growing Peppers Indoors – Guidelines & Tips

Peppers are a popular cooking ingredient around the world, and they’re also a great plant to grow at home. Growing peppers indoors can be an especially rewarding task as you’ll have full control over the variety of pepper and the environmental conditions needed for growth. Here are a few guidelines and tips for successfully growing peppers indoors.

Choose the Right Pepper Variety

When choosing a pepper variety for indoor growth, look for plants that are shorter in stature and more compact. Varieties such as sweet bell peppers, jalapenos, banana peppers, and chilis are all excellent choices for indoor pepper gardening. These varieties are more likely to grow well in a limited space while they don’t require too much maintenance.

Pick the Right Potting Soil

The soil you use for your pepper plants will make all the difference in the health and growth of your pepper plants. Look for potting soil labeled specifically for peppers. These soils are formulated for optimum growth and will provide your plants with the appropriate levels of nutrients and drainage. Avoid regular garden soil or compost, as these can often contain too many unnecessary elements and can lead to root rot or disease.

Provide Plenty of Light

One of the most important aspects of successfully growing peppers indoors is to provide your plants with plenty of light. On average, pepper plants need at least 6 hours of direct sunlight per day. If you don’t have access to a south-facing windowsill, you can always use a fluorescent or LED grow lamp to give your plants the light they need. If you opt for the latter, make sure you keep your lamp about 8 to 10 inches away from the tops of the plants.

Maintain a Consistent Temperature

It’s very important to keep your peppers at a consistent temperature. Pepper plants need a minimum temperature of 70°F (21°C) to thrive. If your home’s temperature dips below 65°F (18°C), your plants won’t be able to set fruits. If necessary, supplement your existing heating system with a space heater, or move your plants to a warmer location.

Water Regularly

Consistent watering is essential to pepper plant growth and development. Your plants should be watered often enough to keep the soil evenly moist. Aim for about 1–2 inches of water per week. Too little water can cause blossom drop and inhibit fruit production, while too much water can lead to root rot and other issues.

Fertilize and Prune

Just like other plants, peppers need to be fertilized in order to remain healthy and strong. Use a balanced fertilizer formulated for peppers and apply it according to the product instructions. Additionally, pruning your pepper plants can help increase air flow and boost productivity. When pruning, remove any damaged or dead leaves to create an open canopy and encourage greater growth.

Harvesting Peppers

Good things come to those who wait! Pepper plants usually take about 75 to 90 days from planting to harvest. When the peppers are about 3–4 inches in size, they are generally ready to be picked. Hold them gently between your thumb and forefinger, and twist until the pepper easily comes off the plant.


Growing peppers indoors can be a fun and rewarding activity. Taking the time to do your research and carefully choosing the variety, soil, and environment for your plants is the key to success. With the right care and attention, you’ll be able to enjoy the flavors of homegrown peppers all year round!
