Fill container with soil, sprinkle oregano seeds, recommend to over-seed it because ¼ seeds may not germinate. There’s no need to cover oregano herb seeds with soil. Simply mist them with water and cover the seed tray or container with plastic. Place this in a sunny location to germinate. Oregano seeds usually germinate within about a week or so. Once the seedlings have reached approximately 6 inches (15 cm) tall, the plants can be thinned down to about a foot (30 cm) apart. Oregano plants can be set out or transplanted in the garden once the risk of frost has passed. Locate oregano in areas receiving full sun and in well-drained soil.
Oregano is a strong-flavored herb sometimes called wild marjoram (it is closely related to sweet marjoram). Oregano (Origanum vulgare) is an easy-care herb that can be grown indoors or out in the garden. As it is native to hot, arid regions, the oregano plant is perfect for growing in areas prone to drought. Growing oregano is easy. Oregano can be grown from seeds or cuttings. Seeds should be started indoors prior to your region’s last expected frost. If you live in a colder part of the world, you may want to start your plant indoors and transfer it outside when the weather warms up. A fully grown oregano plant will be about 2 to 2½ feet tall (60 to 76 cm) and about 2 feet wide (60 cm). For best results in your garden, you should give your oregano about 10 inches (25 cm) of space between plants. Established plants do not require much attention. In fact, these drought-tolerant herbs need watering only during excessively dry periods. Oregano doesn’t need to be fertilized either, as these hardy plants can typically take care of themselves. For optimal flavor (if growing oregano for kitchen use) or more compact plant growth, flower buds can be pinched out as they begin to bloom. Oregano herb plants are commonly used for cooking. Oregano leaves can be stored whole, placed in freezer bags and frozen. Store unwashed leaves in the refrigerator for a few days in a sealed bag. Dry leaves for long storage. Dry leaves on a cookie sheet in a barely warm oven for half a day. Or dry leaves by hanging cut stems together upside down in a cool, dry, dark place or in a paper bag for about 2 weeks. Oregano plants should be cut back to the ground and covered with a layer of mulch for overwintering outdoors. Container grown plants can be brought inside for growing oregano indoors year-round.
