Growth Stages

Seedling

2-3 weeks

Tiny plants with 2-4 small leaves emerging from soil; delicate and pale green

Keep soil consistently moist; provide bright, indirect light; protect from strong winds; maintain 65-70°F temperature

Vegetative

3-4 weeks

Bushy growth with increasingly fragrant green foliage; stems elongate with multiple leaf nodes; plant develops characteristic citrus aroma

Pinch back growing tips to encourage bushiness; maintain consistent moisture; begin light feeding with balanced fertilizer every 3-4 weeks

Pre-flowering

2-3 weeks

Stems strengthen and thicken; foliage becomes denser and more fragrant; flower buds begin to form at stem tips

Continue pinching to delay flowering if maximum leaf production desired; reduce nitrogen fertilizer to encourage flowering; ensure adequate sunlight

Flowering

4-6 weeks (continuous from mid-summer through fall)

Delicate purple to pink flowers arranged in terminal spikes; plant reaches mature height; aromatic oils peak in foliage and flowers

Allow some flowers to bloom for pollinator attraction; deadhead spent flowers to encourage more blooms; harvest regularly for culinary use

Established Perennial

Year-round; multiple seasons of production

Strong, vigorous plant with woody base; dies back in winter in cold zones; regrows vigorously in spring from rhizomes

Cut back after frost in fall; mulch in fall for winter protection in zones 5-6; divide every 2-3 years to rejuvenate; fertilize lightly in spring

Harvest Tips

Begin harvesting once plant has at least 6-8 true leaves (typically 4-6 weeks after planting); pinch off top 2-3 sets of leaves to encourage bushing; harvest in morning after dew dries for best aroma and oils; regular harvesting promotes more vigorous growth; can harvest continuously throughout growing season; for drying, cut stems just before flowering for maximum essential oil content
