If there are many independent health and farmers markets then grow both culinary and herbs for tea or medicinal healing. After you decide on the type of herbs that you will grow for a profit you would then check your business budget. Know before you start a home business what funds are available. Never start a business that cannot afford.
Dill is my best selling herb. I sell out of it in June. Here in my area people use it to pickle cucumbers.
Start your herb business small and grow it over the years.
Start up costs for herb garden are minimal and the time required to care for your plants is part-time. Even if you work outside the home, you can maintain an herb garden and grow herbs for a profit.
