Spearmint

How to Grow: Spearmint (Mentha spicata)

Start Indoors Sow seeds indoors 6-8 weeks before the last expected frost. Spearmint seeds are tiny and require light for germination.

Sowing Depth: Scatter the tiny seeds lightly on the surface of moist seed-starting mix. Gently press them down, but do not cover them, as they need light to germinate.
Germination Time: Seeds typically germinate in 10-15 days at temperatures around 65-70°F (18-21°C). Keep the soil consistently moist (a clear dome helps).

Light & Growing Spearmint is adaptable but thrives with consistent moisture and some sun.

Sunlight: Prefers partial shade (4-6 hours direct sunlight) in hotter climates, which helps prevent scorching and keeps leaves tender. It can tolerate full sun in cooler regions if kept consistently moist.
Growth Habit: Spearmint grows as a spreading perennial, typically 1-2 feet tall, with bright green, often crinkled or textured leaves. It produces spikes of small purplish or white flowers in summer, which are attractive to pollinators.
Maintenance: o Containment (Crucial!): Like all mints, Spearmint is an extremely aggressive spreader. It is highly recommended to plant it in containers or raised beds with physical barriers (like bottomless buckets sunk into the ground) to prevent it from taking over your garden. o Pinching & Pruning: Pinch back stem tips regularly to encourage bushier growth and prevent flowering, which can reduce leaf flavor. Cut back plants by about one-third after flowering or a major harvest to encourage new, tender growth. o Winter Care: Spearmint is very hardy (Zones 3-11). It will typically die back to the ground in winter and re-emerge vigorously in spring.

Harvesting Spearmint Regular harvesting promotes more tender growth and keeps the plant productive.

Timing: Begin harvesting once the plant is well-established and has a good amount of foliage (at least 6-8 inches tall). You can harvest as needed throughout the growing season, typically before it flowers for the best flavor.
How to Harvest: o Snip Stems: Use clean scissors or a sharp knife to snip off entire stems, leaving a few inches of growth at the base to ensure regrowth. o Major Harvests: For drying or freezing, you can take larger harvests, cutting back up to two-thirds of the plant. It will quickly regrow.
Storage: o Fresh: Store fresh spearmint by placing stems in a glass of water on the counter (like a bouquet) or in the refrigerator, covered loosely with a plastic bag. o Drying: Spearmint dries well, though it loses some intensity. Hang small bunches upside down in a cool, dark, well-ventilated area, or use a dehydrator. Once dry, strip leaves from stems and store in airtight glass jars away from light and heat. o Freezing: Freeze whole leaves or chopped spearmint in ice cube trays with water for later use in drinks or cooking.
