How to Grow Cayenne Peppers Indoors

By Robin Coe ; Updated September 21, 2017
Indoor cayenne makes a great decorative plant.

Cayenne peppers are relatively easy to grow indoors, and they add both a spicy kick to recipes, and attractive decoration to your kitchen. In the fall, you can string and hang the extra peppers to dry for later use. Cayenne peppers are high in vitamin A, which is great for vision and promoting smooth skin.

Fill your starter peat pots with potting soil. Press a seed 1/4 inch into the soil of each pot, and cover them with soil.

Set your starter plant pots under a grow light for 16 hours each day.

Water your soil immediately after adding the seed. Continue watering each day by making sure that the soil is moist but not soggy.

Once your plants are two inches tall, add potting soil to a pot with good drainage. Choose a 6-inch or larger size pot. The bigger your pot is, the larger your cayenne plants will grow.

Mix peat into your soil until it is loamy. Dig a hole into the center of the soil in each pot that is big enough for the peat pots. Stick one peat pot into the soil of each planter pot, and then cover them completely with soil.

Add liquid fertilizer that is diluted to 1/2 its normal strength to the soil in each plant pot. Repeat the application once a week.

Cover the top of the soil with mulch. Place your plants in a window facing the south or west so that they get plenty of morning sun, or continue to keep them under grow lights for 16 hours a day. They need plenty of light to produce peppers.

Keep the soil moist with water each day. Re-pot and prune your plants in the spring.
