- 1). Find a sunny location in your home to locate your indoor herb garden. A sunny window with southern or eastern exposure is best because herbs need at least six hours of sunlight per day. However, a western window with harsh afternoon sunlight may be too hot for some herb plants. If locating near a western window, think about setting the container where it gets direct sun only one or two hours during the day and bright light the rest of the afternoon. You need to rotate the plants every three days when they are located near a window, so all sides of the plant can be exposed to sunlight.
Another option, if you do not have a sunny window, is to place the herbs one foot away from two 40-watt white fluorescent bulbs for 16 hours each day. - 2). Buy or order herb seeds or plants. Good herbs for indoor herb gardening are parsley, mint, winter savory, chives, rosemary and thyme. These are herbs that can survive in less than optimal sunlight conditions.
- 3). Choose attractive planting containers or pots for your herb plants. All herb plants must have good drainage, so all containers need drainage holes located in the bottom or bottom-side of the container. Be sure the containers are compatible with the location you have chosen to create your indoor herb garden.
- 4). Fill the containers with new potting soil from a sealed bag that was not stored outdoors. Potting soil exposed to the outdoors can carry insect and disease pests.
Add plants or plant seeds at the depth recommended on the seed packet. Some herb seeds should be planted as deep as 1/4 inch, while others are simply pressed into damp soil. - 5). Keep the soil around the plants damp, but not wet, during the growing period. Every two weeks, water the herbs with a water-soluble fertilizer diluted at half strength. Avoid over-fertilization. Adding lots of fertilizer to your indoor herb garden gives the herbs a bad taste and allows damaging fertilizer salts to build up in the soil.
