Quick Facts:
- Days to harvest: 60
- Hardiness: Frost-sensitive (perennial in warmer climates, treat as annual in Zone 8b or overwinter indoors)
- Light needs: Full sun
- Water needs: Low to moderate (well-draining; drought-tolerant once established)
Planting:
- Start indoors 6–8 weeks before last frost. Seeds are tiny and slow to germinate.
- Timing: Zone 8b — start indoors Feb–Mar, transplant after last frost in May.
- Depth: Surface sow or barely cover, 1/8 in — needs light to germinate
- Spacing: 8–12 in apart
Care:
- Germination is slow (7–14 days) and seedlings are small at first — don't give up on them.
- Pinch back tips regularly to encourage bushiness and prevent early flowering.
- Once flowering begins, flavor shifts slightly — harvest heavily before this happens if you want leaves at peak flavor.
- To overwinter in Zone 8b: bring pots indoors before first frost, grow in a sunny window.
Harvest:
- Begin harvesting once the plant is 6+ in tall, taking no more than a third at a time.
- Best flavor just before flowering — this is when aromatic oils are highest.
- Fresh use is excellent; also dries well. Hang in bunches or strip leaves and spread on a screen.
- Add fresh marjoram at the end of cooking to preserve its delicate flavor.
