Growth Stages

1

Seedling

2-3 weeks

Tiny heart-shaped cotyledons emerge, followed by true minty-scented leaves

Keep soil lightly moist but not wet. Provide bright light. Thin seedlings to 12 inches apart.

2

Vegetative Growth

4-6 weeks

Plant develops bushy mounds of small, aromatic green foliage; stems become woody at base

Water moderately. Avoid overwatering. Pinch back tips to encourage branching and fuller habit.

3

Flowering

8-12 weeks (spring through fall)

Delicate two-lipped flowers in pink, purple, lavender, or white appear along stems in dense clusters

Deadhead spent flowers to encourage continuous blooming. Water during dry spells. Flowers attract bees and butterflies.

4

Seed Development

4-6 weeks

Flowers fade, revealing tiny seed-bearing calyces; foliage may yellow slightly

Allow some flowers to dry on plant if self-seeding is desired. Cut back in late fall to tidy plant.

5

Dormancy

2-4 months (winter)

Plant dies back in winter in northern zones; may remain evergreen in milder zones

No watering needed. Cut back dead stems in early spring. Mulch lightly in zone 5 for winter protection.

Harvest Tips

Pinch fresh leaves and flower buds anytime during the growing season for herbal use; best flavor before flowers fully open. For drying, harvest in mid-morning after dew dries but before heat peaks. Cut stems just above leaf nodes to encourage bushiness. Harvest no more than one-third of plant at a time.
