Spearmint
Also known as: Mentha spicata
What's special about Spearmint
The mojito / tabbouleh mint. Sweet, classic mint flavor.
Growing this variety
Spearmint follows the same growing basics as Mint. Variety-specific maturity above; everything else below applies to the whole Mint family.
Germination
Spacing & depth
How to plant
Press seed onto damp mix. Keep humid until germination. ALWAYS plant in a pot or sunken container — mint runs and takes over beds within one season.
Grower's tip
Rampant spreader. If planted in-ground, sink a pot 12" deep to contain the roots.
Soil preferences
Light, well-drained loam. Most culinary herbs suffer in soggy soil.
6.0–7.5 (neutral)
A single fork of finished compost at planting is plenty — over-feeding weakens flavor.
Watering
Consistent moisture while young; let the top inch dry between waterings once established.
Water at the base in the morning to keep leaves dry and prevent mildew.
Overwatered: yellow lower leaves, damp-smelling soil, wilt that doesn't rebound. Underwatered: crispy tips, purple stems, sudden bolting.
Prefers top-watering — Top-water at the base. Peppers are prone to leaf spot and phytophthora when foliage stays wet.
Temperature tolerance
65–85°F (18–29°C) ideal
55–65°F (13–18°C)
Most annual herbs are frost-tender; perennial herbs (sage, thyme, oregano, mint) tolerate frost once established.
Container growing
Yes — great in containers
6–10 in (15–25 cm) wide, minimum 6 in deep
Herbs thrive in pots — group by water needs (Mediterranean herbs on the drier side, basil/parsley/cilantro on the wetter).
Succession planting
Sow leafy herbs (basil, cilantro, dill, parsley) every 3–4 weeks for a steady supply.
Detailed harvesting
Pinch or snip stems just above a leaf pair — never strip a plant of more than one third at a time. Harvest before flowering for peak flavor.
Post-harvest storage & preservation
Air-dry small bundles upside-down in a dark airy spot, or freeze chopped in olive oil in ice-cube trays. Store dried leaves whole in a jar; crush just before use.
Culinary, medicinal & other uses
Culinary flavoring — fresh in salads and finishing, dried in slow cooks and rubs. Many herbs (basil, mint, chamomile) also infuse oils, vinegars, or teas.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Mostly insect-pollinated; some (basil, mint) self-pollinate.
Isolate different varieties of the same species by 150 ft or cage/bag flower heads to keep strains true.
Let one plant flower fully; harvest brown, dry seed heads into a paper bag; rub free and store dry.

Track packets and loose seeds you already have. Private to your account.
Par level — leave at 0 for no alert. Anything below par shows on Seed Starting and your shopping list.
From your kitchen — grow mint from what you already have
Most annual and biennial herbs give seed if you stop harvesting one plant and let it flower.
- 1Choose your best-flavored, latest-to-bolt plant to be the seed parent.
- 2Let it flower, then wait for the seed heads to dry brown and papery on the plant.
- 3Cut whole stems into a paper bag before they shatter.
- 4Rub or crumble the heads to release seed; sieve out the chaff and store dry in an envelope.
Storage: Most herb seed stays viable 2–4 years dry.
