Home gardeners who grow their own herb gardens have the benefit of healthy, tasty ingredients handy at all times. Herbs grown indoors require significantly less care than those grown outdoors. Indoor herb gardens are close at hand for cooks, and there are little to no risks for weeds or pest infestations.
Fill small flower pots with potting mix. Do not tamp the potting mix down; leave it loose so that developing root systems will be able to break through easily.
Plant seeds or seedlings in the potting mix. Plant the seeds at the depth indicated on the seed packets. If there are no instructions, the general rule is to plant seeds at a depth of 1 1/2 times their diameter. Water the seeds or seedlings until the potting mix is moist throughout.
Place the flower pots or containers in or near a sunny window. Four to 8 hours of sun per day is sufficient. If the window gets closer to 16 hours of sunlight per day, filter the light with a sheer shade.
Water the plants when the soil feels dry to the touch. Herb plants do not like over-watered conditions. Avoid watering heavily or frequently. Wait until the soil feels almost dry, and add enough water to moisten the soil.
Fertilize if desired. Use an organic fertilizer, since the plants are edible. Follow the directions on your package of fertilizer, for mixing and dosage instructions.
Prune regularly to encourage new growth. Use your hands or kitchen shears to snip off leaves and stems from the top of the plants.
