Mint - Key Growing Information
DAYS TO GERMINATION: 10-14 days at 72–75°F (22–24°C).
SOWING: Transplant (recommended): Start 6-8 weeks before setting out in early spring; young plants can withstand some freezing. Sow seeds on top of the growing medium, gently pressing them into the soil mix. Do not cover, as the seeds require light to germinate. Keep moist and germinate at a temperature of 55-65°F (13-18°C). Transplant seedlings into individual containers when the first true leaves appear. Pinch off the top sets of leaves regularly starting at the seedling stage for a bushier, healthier plant. When 3-4" tall, transplant outside, spacing plants 12-18" apart in rows 18" apart. Since mint spreads quickly, choose location carefully, possibly with a growth barrier. Water deeply once in a while, rather than watering the plants lightly more often. To prevent the spread of leaf diseases, water the soil and not the foliage. Cut back the plants to the ground before winter. This will make for healthier, more prolific plants the following year.
LIGHT PREFERENCE: Sun/Part Shade.
SOIL REQUIREMENTS: Best in rich, moist soil that is high in organic matter with good drainage.
PLANT HEIGHT: 18-36".
PLANT SPACING: 12-18".
HARDINESS ZONES: Zones 4-9.
HARVEST: Pick mint regularly for better production. If harvesting the entire plant, wait until just before flowering. Individual leaves may be harvested the first year once the plants are established. Dry in a warm, well-ventilated location that is out of direct sunlight, turning the leaves and flowers occasionally as they are drying.
Note: May become invasive in field plantings, if allowed to do so.
SCIENTIFIC NAME: Mentha spp.
