How To Plant Peppermint Plants?
The best time to plant a peppermint plant is in the early spring months. Ensure that the final frost has passed. Here are a few simple steps you need to follow while planting peppermint using seeds:
- Use a seed starting mix and press the peppermint seeds onto its surface.
- Avoid pressing the seed too hard, and do not bury the seeds in soil.
- Keep the soil moist. You will notice germination in five to ten days.
- Tip: If you want germination to start sooner, keep the soil warm with the help of a heat mat.
- Transplant the seedling in the garden with well-draining soil.
- Ensure you space the peppermint seedlings at least 20 to 26 inches apart.
How to Propagate Peppermint?
One of the easiest ways to plant mint is by propagating it from cuttings. Here are the steps you need to follow:
- Using a sharp knife or scissors, cut a healthy peppermint stem about 4 to 6 inches long just below the leaf node.
- Remove the leaves from the lower half of the stem and submerge the cutting in distilled water.
- Place the pot in a location with good air circulation and bright light.
- Once the roots are formed, transplant the cuttings into a pot filled with soil or directly sow them in the garden.
Tip
If you are planting peppermint in a pot, ensure that it has proper drainage holes.

Essential Peppermint Plant Care Tips
The peppermint plant is low-maintenance and does not need much attention. Below is a list of essential care tips for the plant:
- Choose a location that receives direct morning sunlight and gets partial shade in the afternoon. This will keep the leaves fragrant and fresh.
- Peppermint is adaptable to any soil, but the ideal soil is rich, loamy, and moist.
- Water the soil at regular intervals to keep it constantly moist. Avoid overwatering the plant because mints cannot tolerate standing water, which leads to soggy roots and eventually harms the plant.
- Avoid fertilising peppermint because fertilisers might affect its flavour. Instead, use organic compost, if required.
- Prune the peppermint plant once every 20 days after the plant has established, up to 4 to 6 inches tall. This will not only help the plant to stay in structure but also promote the emergence of new leaves.
Tip
Make sure that you are aware of peppermint’s invasive nature before planting it. If you are planning to directly plant it into the ground, consider installing soil barriers. It is better to grow the plant in a container and then later sink it into the ground or another larger container.
