Want to grow your own mint indoors? You can start growing mint indoors from cuttings or from the seeds. Here is how.

Growing Mint from Cuttings

The easiest way to grow a new mint plant indoors is by starting from cuttings. You can have the roots showing after just two weeks.

  1. Cut a few sprigs of mint of about 5 – 6 inches long just below the node.
  2. Remove the leaves from the bottom half of the sprig.
  3. Place the cuttings in a jar filled with only water.
  4. Keep the jar in a sunny spot with indirect sunlight until roots start to grow.
  5. Once the roots are about 2 inches long, you can transfer the plant to a container with soil.
  6. Fill a container with regular potting soil and water it to make it moist.
  7. Plant the mint with new roots a few inches apart from each other.

Mint plants don’t grow very long, rather they grow horizontally. Keep this in mind when you transferring them to a container.

Make sure there is enough space in between for them to grow. Before you know it the entire container will become a lush bush of mint.

Growing Mint from Seeds

If you are up for a challenge you can try growing mint indoors starting from the seeds. As with any plant, this is a little trickier but since mint loves to grow you do stand a good chance for success.

  1. Fill a container with regular potting soil.
  2. Make small indentations in the top inch of the soil with several inches in between.
  3. Spread the mint seeds across the indentations.
  4. Lightly cover the seeds with soil from the container.
  5. Water the soil frequently so that it stays moist without being soggy.
  6. Keep the pot in a sunny spot with direct sunlight.

Newly germinated mint seeds are very fragile so don’t rush into moving them to a new container. In fact, if you start with a large enough container your can keep them in the same container until they are ready to be used.
