Marjoram, a delightful herb with a sweet pine and citrus flavor, is a cold-sensitive perennial that thrives in warm climates. Often called pot marjoram or knotted marjoram, this undershrub can be grown successfully in home gardens with the right care and attention.
Marjoram prefers well-drained soil and full sun exposure. It thrives in temperatures above 60°F (15°C) and dislikes cold weather. Ensure your garden has these conditions for optimal marjoram growth.
Plant marjoram seedlings or cuttings in early spring, after the last frost. Space them about a foot apart to allow room for growth. Water regularly during dry spells, but avoid overwatering. Prune lightly to encourage bushy growth and prevent flowering.
Marjoram may succumb to powdery mildew if not properly ventilated. Overcrowding can also lead to disease. If your plant becomes leggy or sparse, prune it back heavily in spring for a more compact habit.
Harvest leaves as needed throughout the growing season. Use clean scissors or hand snip the tender tips. You can also propagate new plants from cuttings. Enjoy using fresh marjoram in your cooking or preserve its flavor by drying or freezing.
