Growth Stages

Seedling

2-3 weeks

Tiny seedlings with cotyledons emerge; slow initial growth

Keep soil consistently moist but not waterlogged. Provide 12-14 hours of light daily. Thin seedlings to 12 inches apart.

Vegetative Growth

4-8 weeks

Plant develops multiple stems and spreads outward; small true leaves are aromatic and gray-green

Pinch growing tips to encourage bushier growth. Reduce watering frequency as plant matures. Fertilize lightly every 3-4 weeks with balanced fertilizer.

Establishment

4-6 weeks

Plant becomes woody at the base and forms a dense, spreading mound 12-18 inches tall and wide

Reduce watering; plant is becoming drought-tolerant. Weed carefully to avoid disturbing roots. Mulch around base to suppress weeds.

Flowering

6-8 weeks

Small white, pink, or purple flowers appear in terminal spikes; flowering occurs mid to late summer

Allow some flowers to remain for pollinator benefit and seed production. Harvest leaves before flowers fully open for strongest flavor.

Harvest & Perennial Dormancy

Continuous through growing season; dormant in winter (zones 4-7)

Foliage remains harvestable through fall; plant dies back or becomes evergreen depending on zone; regrows from roots in spring

Harvest leaves anytime during growing season. In fall, cut back to 6 inches above ground to prepare for winter. In warmer zones, it may remain semi-evergreen.

Harvest Tips

Begin pinching leaves when plant is 6 inches tall. Harvest in the morning after dew dries for peak essential oil content. Cut stems back to healthy leaves; never remove more than one-third of the plant at once. Continuous harvesting promotes bushier growth. For winter storage, harvest before first frost and hang-dry or freeze in oil.

Fun Facts

🌱 Oregano's name comes from Greek words meaning 'mountain joy' (oros meaning mountain, and ganos meaning joy), as it naturally grows on Mediterranean hillsides.
🌱 The stronger the sunlight and the drier the conditions, the more concentrated the essential oils in oregano leaves, making sun-stressed plants more flavorful.
🌱 Oregano is one of the few herbs that actually becomes more flavorful when dried than when fresh, as the drying process concentrates its volatile oils.
