Mint grows horizontally, so choose a wide, shallow container. Ensure it has good drainage holes to avoid waterlogging.
Use a general-purpose potting mix. Mint prefers slightly acidic to neutral pH levels, between 6.0 and 7.0.
You can start mint from seeds, but it's usually easier to begin with a cutting or a small plant from a nursery. Plant it just below the surface of your potting mix.
Place the container in a spot with plenty of sunlight, like a south-facing window. Mint needs about 4-6 hours of sunlight each day.
Keep the soil consistently moist, but be careful not to overwater and make it soggy. It's better to water a little each day rather than a lot at once.
Regular harvesting encourages more growth. Pinch off the top leaves once the plant is about 6 inches tall.
If you see pests like aphids or spider mites, use an organic insecticidal soap to get rid of them.
