The first thing you will want to do is decide what plants you want to grow. Chamomile and peppermint are both easy to grow and delicious. You can start with seeds or seedlings. If you do start with seeds you will find it is relatively easy to plant them outside in the late spring, forgoing starting the plants under lights in your house in the winter. Soon enough your hardy little herbs will sprout, and you're in business.
Herbs are very tough plants, seeming to thrive on neglect.
Most herbs do not like their soil to be to rich, so you do not have to worry about fertilizing. They also rarely need to be watered, unless they are planted in pots, which have a tendency to dry out quickly. You may want to put a thin layer of mulch or fine gravel on the surface of your soil, to prevent weeds from growing among your herbs. Insects or disease rarely bothers herbs. Let your plants grow until they are stocky, and then you can start harvesting leaves for tea.
