How to Grow Peppermint from Seed: A Simple Guide for Beginners

Want to add a refreshing twist to your garden? Look no further than planting peppermint seeds! Not only is peppermint loved for its fragrant scent and delicious taste, but it’s also incredibly easy to grow. Whether you have a green thumb or not, our step-by-step guide will help you successfully grow peppermint from seeds in no time.

Understanding Peppermint Plants

Peppermint (Mentha x piperita) is a versatile plant known for its cool, refreshing fragrance and taste. Native to Europe and the Middle East, it’s now grown worldwide. Aside from culinary uses, it also has medicinal purposes as it’s been used to alleviate digestive, respiratory and muscular problems.

Peppermint is an aggressive grower, often considered a perennial herb. This means that with proper care, your peppermint plant can regrow year after year. It can potentially become invasive, so consider planting in pots, raised beds or areas where it can freely sprawl.

Selecting Your Peppermint Seeds

When starting peppermint from seeds, it’s crucial to ensure that you are starting with high-quality seeds. Purchase your seeds from a reliable retailer. Alternatively, you may gather seeds from a mature peppermint plant. Just bear in mind that peppermint is a hybrid plant, and seeds from hybrid plants may not grow true to form.

Ensure that the seeds are not old as old seeds have a lower germination rate. Ideally, get fresh peppermint seeds for the best results.

Starting Your Seeds Indoors

Peppermint can be directly sown into the ground, but starting the seeds indoors gives you a head start. Begin by soaking your seeds in water for 24 to 48 hours – this softens their coat and encourages germination. After soaking, place the seeds on a seedling tray filled with groovy soil mix. Keep the seeds moist and provide sufficient light.

Normally, peppermint seeds will sprout within 10-15 days. Once they grow to 3-4 inches tall, they are ready to be transplanted outdoors. As a rule of thumb, transplant seedlings after the last spring frost.

Planting The Seedlings

Find a sunny or partially shaded spot in your garden. Peppermint prefers a well-drained, fertile loam with a neutral to slightly alkaline pH. Dig a hole wide enough to accommodate the root ball of each seedling. Place them in the hole and fill it up with soil. Ensure the top of the root ball is level with the surface of the ground.

After planting, water thoroughly. Space multiple plants 18-24 inches apart as peppermint tends to spread aggressively.

Caring for Your Peppermint Plants

Once your seedlings are established, they require little attention. Water them regularly during dry periods, but be careful not to overwater. Lack of water can make the leaves taste bitter, while overwatering can cause root rot.

If you’ve planted your peppermint in a pot, remember to repot it every two years or so to replenish the soil. Regular pruning will also keep your peppermint plant bushy and manageable.
