Germination & Seedling
2-3 weeksTiny seedlings emerge 7-14 days after planting with small oval cotyledons. True leaves begin appearing shortly after.
Keep soil consistently moist but not waterlogged. Provide bright light immediately. Thin seedlings to 1-2 inches apart. Maintain 65-75°F temperature.
Vegetative Growth
4-6 weeksPlant develops bushy foliage with multiple stems. Fuzzy, aromatic green leaves expand rapidly. Root system establishes.
Water moderately, allowing soil surface to dry slightly between waterings. Begin fertilizing every 2-3 weeks with balanced fertilizer. Pinch growing tips to encourage bushiness.
Pre-Flowering
2-3 weeksPlant reaches mature size with dense foliage. Flower buds begin forming at stem tips.
Continue pinching off flower buds if prioritizing leaf production for cooking. Reduce nitrogen fertilizer to encourage flowering if flowers are desired.
Flowering
4-8 weeks (mid-summer through early fall)Delicate pink, purple, or white flowers appear in dense clusters at branch tips. Plant reaches full aromatic potential.
Do not fertilize during flowering. Water only when soil is dry to touch. Flowers attract pollinators and beneficial insects. Harvest leaves before peak bloom for best flavor.
Dormancy & Winter
2-4 monthsFoliage growth slows significantly. In mild climates, plant remains semi-evergreen. In cold zones, foliage dies back but roots survive underground.
Reduce watering significantly. Cut back dead stems in spring after frost danger passes (zone 4) or in late winter (zones 5-7). Mulch lightly in zones 4-5 for winter protection.

Harvest Tips
Begin harvesting leaves once plant is 6-8 inches tall, pinching off stem tips to encourage bushiness. Harvest regularly in early morning after dew dries for best flavor and aroma. Cut no more than one-third of plant at a time. Best flavor occurs just before flowering; harvest heavily before flowers fully open. Dried oregano is more concentrated in flavor than fresh.
