Organic gardening with herbs is easily done with two basic rules; no pesticides and no chemical fertilizers. Herbs are often used in cooking and growing them organically is safer. You can create organic herb gardens as a separate garden space or integrate herbs into a perennial flower garden. Taller herbs, such as Angelica, grow well mixed with roses and delphiniums. Organic care of the soil enhances the health of perennial herbs, such as tarragon.
The American Herb Society describes Angelica as an herb that grows from 6 to 10 feet tall, with greenish-white flowers in large club-shaped heads. The flowers bloom at midsummer and can grow to 6 inches in diameter. All parts of the plant are fragrant. It is a biennial plant that re-seeds in the wild. The roots and leaves are harvested for medicinal use as a remedy for digestive problems. Grow Angelica organically by incorporating compost into the seed bed when you plant it, and give it a side dressing of fertilizing compost after the bloom period. Herbs do not need a lot of water or fertilizer.
Use homemade compost as a soil additive when planting chives. Chives are a member of the lily family and they are grown for their onion or garlic tasting leaves. It is a perennial plant that dies back each winter and returns in late spring. Perennials thrive when they are organically cared for with fertilizing compost each winter when they are dormant. The underground bulbs create the next season's growth at that time. Chives grown from seed take two years to become a usable plant. They are often sold as young plants. The clump increases annually by bulb division and can be separated into new plants every three years.
Tarragon is another hardy perennial that thrives with organic gardening care. It grows from old roots each year to a height of 2 to 3 feet. The leaves are narrow, pointed, smooth and dark green. Leaves are cultivated for culinary use because they taste slightly like anise. Tarragon thrives in dry conditions. Do not over-water because it is subject to fungal problems. Use organic mulch in the winter dormancy period when the roots freeze.
Organic herb gardens often contain oregano, which is a mainstay of Mediterranean cooking. Oregano is a tender perennial plant in the wild but is grown as an annual. Enhance the soil with organic compost when oregano is planted but do not fertilize regularly. This herb creates its distinctive flavorful leaves from dry, poor soil conditions. Good drainage is essential.
