USDA Grow Zone: 6-11
Garden Uses: Herb gardens. Edging. Effective in window boxes, hanging baskets or containers.
Soil pH: 6.0-9.0, Ideal 6.0-8.0. Marjoram prefers to be planted in well-drained soil.
In short growing seasons, start marjoram inside about a month before the last frost; sow the seeds just beneath the surface of the soil and keep evenly moist at a temperature of 65-70 degrees F. Germination can be very slow, taking up to 21 days.
Transplant well after the last frost, since marjoram cannot tolerate cold. Place the seedlings 10-12" apart in light, well drained soil and full sun.
Marjoram can also be direct sown after the last frost, planting the seeds 6-8" apart and thinning the seedlings to 10-12". Marjoram also grows very well as a container plant or houseplant.

Transplant outdoors, either with your own seedlings, starts purchased at the nursery, or cuttings from another plant.
When: Plant outdoors 2 to 4 weeks after last frost date.
How: Dig a hole 4 - 6" deep (depending on the container size). Gently squeeze the sides of the container to release the soil. Remove the plant and soil from the container and place into hole. Surround with additional soil, but don't bury the base of the plant. Give a good watering.
Cold, Cool, Warm, Hot: Marjoram prefers light, well-drained, moderately fertile soil with a neutral pH. Water regularly, but moderately.
When outdoor temp: 55°F to 90°F, optimal temp 70°F to 80°F
When min soil temp: 60°F. Start seeds indoors 6 to 8 weeks before frost or sow seed directly after last frost, when soils have reached at least 60˚ F.
Spacing: 6.0"-8.0", 4 plants per sq ft. Plant 6 to 8" apart.

Marjoram is pretty low maintenance as long as it has well-drained soil and sun. It pretty much looks after itself.
Water Needs: Low. Marjoram is adapted to a Mediterranean climate and suffers more from too much water than not enough.
Fertilizer Needs: Light. Marjoram should be grown in soil that is lightly fertilized.
Watering: Water, 0.5 inch(es), every 2 weeks. Marjoram is very drought tolerant, but will grow best if it gets some water when the soil is drying out.
Pruning: 1 time. If the plant starts to get woody, cut it down to within a couple of inches of the ground. This will stimulate it to send up fresh new growth.

Harvesting
Ripening:
Wait until the plant has reached a height of 6 to 8" tall before picking leaves for use. Harvest leaves as desired. Leaves retain flavor well when dried; dry away from sun to preserve color and flavor. Store in an airtight container.

Medicinal
Sweet marjoram is mainly used as a culinary herb, but is also medicinally valuable due to its stimulant and antispasmodic properties. It is a good general tonic, treating various disorders of the digestive and respiratory systems. It has a stronger affect on the nervous system than the related oregano (O. vulgare) and is also thought to lower the sex drive. Because it can promote menstruation, it should not be used medicinally by pregnant women though small quantities used for culinary purposes are safe. The herb is antiseptic, antispasmodic, carminative, cholagogue, diaphoretic, diuretic, emmenagogue, expectorant, stimulant, stomachic and mildly tonic. It is taken internally in the treatment of bronchial complaints, tension headaches, insomnia, anxiety, minor digestive upsets and painful menstruation. It should not be prescribed for pregnant women. Externally, it is used to treat muscular pain, bronchial complaints, arthritis, sprains and stiff joints. The plant is harvested as flowering begins and can be used fresh or dried. Marjoram is often used medicinally in the form of the essential oil, about 400 grams being obtained from 70 kilos of the fresh herb. The oil is used as an external application for sprains, bruises etc. The essential oil is used in aromatherapy. Its keyword is "Muscle relaxant".
