Sweet marjoram thrives in full sun and has good drought tolerance once it is well established. It's important to plant marjoram in free-draining soil to avoid problems with root rot in wet conditions.

What is the difference between marjoram and oregano?

Marjoram and oregano are often confused. Although they are closely related, they are not the same species. Oregano (Origanum vulgare) is a hardy perennial sub-shrub native to most of Europe, including the UK. It's often known as wild marjoram and is widely used as a dried culinary herb.

Marjoram is not as hardy as oregano. It has a delicate, sweeter taste and is usually used fresh. Pot marjoram (Origanum onites) is another culinary Mediterranean species. It closely resembles oregano and is hardy in milder areas of the UK. Both marjoram and oregano are toxic to pets.

Where to grow marjoram

Plant marjoram in a sheltered sunny spot in free-draining soil with an alkaline or neutral pH. Plants grow into bushy mounds that reach around 60cm in height.

Marjoram combines well with other Mediterranean herbs in borders and raised beds. It will also grow well in containers on a sunny patio or in a greenhouse or conservatory.

How to plant marjoram

Sow marjoram seeds in spring under cover in peat-free seed compost. Harden off plants and transplant into the garden after the last frost. Young marjoram plants that have been bought from a nursery or garden centre can also be planted out in a free-draining, sunny spot once the risk of frost has passed.

Although marjoram is a perennial, it is often grown outside and treated as an annual in the UK. When grown in containers, marjoram can be brought indoors in autumn and overwintered in a sunny spot, ready to put back out in the garden in late spring after the last frost. In summer and early autumn, plants should be harvested regularly to promote new growth.

How to harvest marjoram

The best time to harvest marjoram is on a sunny morning when the leaves are full of essential oils. Remove some flowerheads before they open in midsummer for the best flavoured leaves, but allow plenty to flower to provide food for pollinating insects.

How to prepare and use marjoram

Marjoram is often used fresh in Mediterranean food such as meat, stuffings and pasta dishes. Oregano can be used as a substitute for marjoram. To store, dry small branches upside down in a dark, warm, well-ventilated area for a few weeks. Then strip off the leaves and store in airtight containers. Do not use marjoram while pregnant or breastfeeding.

How to propagate marjoram plants

Marjoram can be sown from seed and plants can be divided in autumn or spring. It can also be propagated from stem cuttings or by layering.

Pests and diseases

Sweet marjoram has few issues with pests and diseases. If plants attract aphids, remove them by hand or with a spray of water, or leave as food for beneficial species, such as ladybirds and birds, such as blue tits.
