Common Mint Seeds

Scatter mint seeds for planting on the soil surface rather than burying them, since they need light to germinate. Press seeds lightly into moist soil and keep them at 65–70°F for best results. Common mint seeds germinate in 10–15 days, though germination can stretch longer in cooler conditions. Start seeds indoors 8–10 weeks before the last frost if you want an early crop, then transplant seedlings outdoors once they've developed a few true leaves. Mint plant seeds don't need stratification or soaking, so the process stays fairly straightforward from packet to seedling tray.

Mint grows best in full sun to partial shade, with a few hours of afternoon shade helping in hotter climates. It tolerates a wide range of soils, but moist, well-drained soil rich in organic matter produces the fullest, most flavorful leaves. Water regularly, since mint's shallow root system dries out faster than deep-rooted herbs. Avoid letting the soil become soggy for extended periods, as this invites root rot. A layer of mulch around the base helps retain moisture during warm stretches.

Pinch back the tips of young mint plants to encourage bushier growth rather than tall, leggy stems. Divide clumps every 2–3 years, since mint can become congested and lose vigor if left unchecked. Harvest leaves any time after the plant reaches 4–6 inches tall, picking in the morning when essential oils are most concentrated. Cut stems just above a leaf node to encourage the plant to branch out again quickly. Harvest regularly to keep it productive and prevent it from becoming woody at the base.
