Choosing the Right Location and Soil
Sweet marjoram thrives in warm, sunny locations. Choose a spot in your garden that receives at least six hours of direct sunlight daily. The ideal soil for this herb is well-drained, fertile, and slightly alkaline. Avoid planting in areas prone to waterlogging as it can lead to root rot.
Starting Sweet Marjoram from Seed

- Depth: Sow seeds ¼ inch deep.
- Spacing: Space seeds 6-12 inches apart.
- Germination: Expect germination in 10-14 days.
Starting Indoors

Caring for Your Sweet Marjoram Plants
Watering
Sweet marjoram prefers consistently moist soil, but it’s important to avoid overwatering. Water deeply but infrequently, allowing the top inch of soil to dry out between waterings.
Fertilizing
Sweet marjoram is a light feeder. You can fertilize once or twice during the growing season with a balanced liquid fertilizer diluted to half strength.
Pruning
Regular pruning encourages bushier growth and prevents the plant from becoming leggy. Pinch off the tips of stems to promote branching.
Harvesting Sweet Marjoram
