Marjoram (Origanum majorana) is an easy to grow herb well suited for growing in containers as well as the garden. There are generally three varieties that are commonly grown: sweet marjoram, pot marjoram, and wild marjoram (also known as common oregano). All types of marjoram are popular for use in the kitchen as seasoning for numerous dishes. They’re also grown for their enticing fragrance.
How to Grow Marjoram Herbs
Although marjoram plants are tender perennials, they are typically treated as annuals as freezing temperatures will cause serious injury or death to the plants.
When growing marjoram plants, it’s generally best to start the seeds indoors during late winter or early spring. Push seeds just below the soil surface. Seedlings can be transplanted outdoors once all threat of frost has passed.
Marjoram should be located in areas receiving full sun with light, well-drained soil. Likewise, marjoram plants can be grown in containers indoors and treated as houseplants.
Marjoram usually grows to a height of 24 to 36 inches (60 - 90cm).
Marjoram plants should be spaced between 15 and 18 inches (38 - 45 cm) apart.
Preferred pH Range
Marjoram will grow in a relatively wide pH range between 6.1 (mildly acidic) and 8.5 (alkaline) with a preferred range between 6.5 and 7.5.
Seed Germination Period
Sweet marjoram seeds will germinate in approximately 8 to 14 days.
