How to Plant Marjoram Seeds

Grow marjoram in a pot year around.

Marjoram is often grown as a kitchen herb. It is grown for its fragrant and flavorful leaves, which are used both fresh and dried in recipes. It is often grown as a potted herb, as it does not tolerate cold weather. Planting marjoram in a pot allows you to place the pot outdoors in spring and summer then bring it indoors to a protected area before winter frost threatens. Planting marjoram from seed is an inexpensive way to introduce this herb to your garden.

Planting in Pots

Fill an 8 inch diameter pot with a quality potting mix. Moisten the mix until it is just damp before adding it to the pot to ensure it is evenly moist throughout.

Sow two to three marjoram seeds in the pot. Plant them to a 1/4 inch depth, then mist the soil surface with water so it is moist.

Cover the top of the pot with plastic wrap to help maintain moisture during the germination process. Place the pot in a warm room to germinate, which usually takes between 7 and 14 days.

Remove the plastic wrap once sprouts appear. Move the pot to a warm, sunny windowsill and water as needed to keep the soil moist.

Place the pot outdoors once all danger of frost has passed in spring. Place it in an area that receives at least eight hours of sunlight.

Water the plant every two to three days or when the soil surface begins to feel dry. Fertilize once a month with a water-soluble, balanced fertilizer following label application instructions.

Planting in Beds

Prepare a garden bed for planting in spring after all frost danger has passed. Lay a 2 inch layer of compost over a full-sun garden bed and till it into the top 6 to 10 inches of soil to aid drainage and soil quality.

Sow marjoram seeds to a 1/4 inch depth. Space the seeds 1 to 2 feet apart in all directions, as marjoram quickly fills in the open spaces and acts a ground cover. Alternately, start the seeds in pots and indoors and transplant the seedlings to garden, following the above spacing.

Water the bed as necessary to keep it moist but not soggy. Generally, supply the herb garden with 1 to 2 inches of water a week.

Lay a 1 to 2 inch layer of bark mulch around the plants once they are 6 inches tall. Mulching preserves soil moisture and also prevents weeds from growing in the marjoram bed.

Fertilize marjoram each spring with a general purpose fertilizer. Follow label instructions for exact fertilizer amounts.


Things You Will Need

  • Pot
  • Potting soil
  • Plastic wrap
  • Fertilizer
  • Tilling equipment
  • Compost


  • Harvest marjoram as needed throughout the growing season. Cut of sprigs of leaves from the outside of the plant and use immediately or dry in a warm room for later use.


  • Marjoram makes an attractive ground cover in outdoor beds but it will die if affected by a freeze. Either treat bedded marjoram as an annual or transplant it to a pot prior to winter.
