Growing Peppers Indoors – Guidelines & Tips

Growing peppers indoors is easier than you may think. With the right planning, you can have a plentiful crop of peppers year round! Here are some basic guidelines and tips to help you get started.

Choosing the Right Pepper Variety

When selecting the pepper variety, look for types that are suitable for growing indoors, such as Anaheim or Caribe peppers. Make sure to choose a variety that has been bred for indoor cultivation, as some varieties are better suited for outdoor growth.

Environmental Conditions

The key to successful pepper growing indoors is providing your plants with the right environmental conditions. Pepper plants need plenty of sunshine, so make sure to place them near a sunny window and rotate them periodically to ensure they get an even amount of light. Peppers also need warm temperatures, so keep the thermostat at a consistent temperature and make sure to provide adequate air circulation.

Soil & Fertilizer

The soil for your pepper plants should be light and fluffy and should contain plenty of organic material. Peppers prefer a slightly acidic pH, so you may need to add lime to the soil if the pH is too low. When it comes to fertilizing, opt for a balanced fertilizer with an NPK ratio of 5-7-5. Fertilize your pepper plants every two weeks during the growing season and use ½ the recommended dose.

Watering & Mulching

Pepper plants need consistent watering, as too much or not enough can cause problems. Water your pepper plants deeply, so that the soil is moist but not soggy. To conserve moisture, you can add a layer of mulch around the plants. This will also help insulate the soil and keep it warm.

Pruning & Support

Pruning your pepper plants will help keep them healthy and encourage increased production. When you first plant them, prune off any dead or damaged leaves and stems. Once the plants get larger, snip off any crowded or weak branches. Provide support, such as stakes or cages, to protect the branches from breaking under the weight of the peppers.

Harvesting & Storage

As your pepper plants start producing peppers, check them often and pick them as soon as they’re ripe. Peppers should be harvested when the fruits are firm and bright in color. To store, keep them in a cool and dry place.


Growing peppers indoors is possible with the right planning and care. Start by selecting a suitable variety, then provide your plants with the right environmental conditions, soil, fertilizer, water, and support. Prune and harvest your peppers as needed, and store them in a cool and dry place. With a bit of work, you can have a plentiful crop of peppers year round.
