Growing Marjoram in Zone 9A

Sweet marjoram is oregano’s gentler, more floral cousin — warmer and sweeter, with less bite. Essential in Mediterranean cooking and dried herb blends.

Zone 9A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Start indoors 6-8 weeks before last frost — slow from seed
• Pinch back flowers to keep plants producing tender leaves
• Harvest before flowers fully open for most concentrated flavor
• Bring indoors as a perennial houseplant in zones 6 and below
• Use fresh or dried — one of the best herbs for drying

Companion Planting

Good companions: vegetables generally, vegetables and beans

Avoid planting near: Fennel

Harvest Timeline

60-90 days; harvest leaves anytime; best flavor just before bloom
