How to Build a Usable Herb Garden

Buy a quality potting mix. Herbs grow much better in potting mix than in outdoor soil because a mix holds moisture well and is relatively free of contaminants. Add fertilizer to enhance the potting mix before planting your herbs. Choose a granular fertilizer for use before planting and a water-soluble fertilizer after planting.

Select a container large enough for the herbs to grow comfortably. Your container should accommodate both the plant and a considerable amount of potting mix. The container should have drainage holes to allow sufficient watering. According to the Utah State University Extension, you can plant up to three herbs in one container that is 12 inches in diameter, using 3 1/2 gallons of potting mix.

Plant herbs that grow well in containers. Certain herbs prefer to be spread out in an outdoor garden. Group plants together that have similar watering needs. Drought-resistant herbs, such as rosemary or thyme, should be planted in terra cotta pots. Herbs that require moisture-rich soil, such as basil and tarragon, should be planted in plastic containers.

Wear gardening gloves to protect your hands from sphagnum moss fungus that may be in the potting mix. Fill the container three-quarters full of potting mix. Plant herbs in the container at the proper depth. If you’re planting from seed, don’t push the seeds deep into the potting mix, but be sure to cover them completely. If you’re planting seedlings, place the roots beneath the surface of the potting mix.

Add water to the potting mix. It should be moist but not thoroughly wet. Herbs that require moisture will need watering once or twice a week, depending on the amount of sun exposure. Herbs that thrive in drier conditions should be watered about every 10 days.
