Seedling
2-3 weeksTiny green leaves emerge from soil; very delicate with characteristic opposite leaf arrangement of mint family
Keep soil consistently moist but not soggy. Provide bright indirect light. Thin seedlings to appropriate spacing after true leaves develop.
Vegetative Growth
4-6 weeksPlant develops bushy form with increasingly aromatic, lance-shaped green leaves on erect square stems typical of mints
Pinch back growing tips in early summer to promote bushier, more compact growth. Maintain consistent moisture. Fertilize monthly with balanced fertilizer.
Budding & Flowering
6-8 weeksFlower buds form at stem tips, developing into characteristic shaggy, pompom-like flower heads in deep purple to violet colors
Deadhead spent flowers to encourage continued blooming. Water at soil level, not overhead, to prevent powdery mildew. Staking may be needed for tall varieties.
Peak Bloom
6-8 weeksMultiple large flower clusters in full display, attracting bees, hummingbirds, and butterflies; foliage highly aromatic when brushed
Continue deadheading for extended blooms. Monitor for powdery mildew and spider mites, especially if crowded or in poor air circulation.
Seed Set & Senescence
4-6 weeksFlowers fade and dry on plant; seed heads form and harden; foliage may decline in appearance, especially in fall
Allow final flowers to remain for seed dispersal and wildlife food, or harvest seeds before fully mature. Cut back plant in late fall or early spring.

Harvest Tips
Harvest leaves and flowers in the morning after dew dries but before heat of the day for maximum flavor and aroma. Pinch off flower clusters individually for fresh use or cut entire stem bundles for drying. For tea, harvest just as flowers open. Dry by hanging bundles upside-down in warm, well-ventilated area for 1-2 weeks. Store dried material in airtight containers away from light. Can harvest continuously throughout growing season without harming plant.
