Peppermint is a hybrid species of mint, a cross between watermint and spearmint. Indigenous to Europe and the Middle East, the plant is now widely spread and cultivated in many regions of the world. This amazingly aromatic herb is one of the oldest herbs used for ritual, culinary, and medicinal purposes. Today it is used for aesthetics, being cherished for its lovely refreshing fragrance and taste.
If there was ever a plant that could make the blackest thumb turn green, it’s mint. Give it enough water and it will happily do its thing. In USDA Hardiness Zones 3 to 8, it will continue to grow – and spread – year after year.
Peppermint is also an excellent option for growing in a container! Since mints are aggressive growers, many people prefer growing them in containers, rather than in their gardens. Imagine picking your own fresh peppermint for cooking, teas, and drinks whenever you need it.
Tips for growing indoor herbs:
Provide as much light as possible. Herbs grown in strong bright light will have the best flavor. Herbs prefer 6-8 hours of sunlight, so a sunny window or sunroom is an ideal location. If you don't have a bright enough window, you can provide artificial light such as a small grow light. Parsley, Mint, and Chives don't require as much light as other herbs.
Keep temps between 60-70 degrees. The most particular herb when it comes to temperature is basil. Basil loves the warmth and would prefer a constant 75 degrees if possible.
Let the plants dry out somewhat between waterings. Test the soil with your finger and if dry 2" below the surface, it's time to water. Water slowly so the water has a chance to absorb in the soil before running out the bottom. Typically plan to water herbs 2 to 3 times per week. Make sure your pots have good drainage, as herbs do not like to be kept in standing water.
Grow each herb in a separate pot when growing indoors.
Fertilize regularly with high-nitrogen plant food.
Provide good air circulation around your plants. Keep indoor herbs trimmed and under control so there is adequate airflow between the plants.
