Research medical plants and herbs to find out which ones best suite your needs and will thrive in your environment. Some require more care than others, thus it's best to know how much daily upkeep is required for each plant. Locate a local source of seeds or clippings.
Select a window sill or spot in the back yard, as appropriate. Put potting soil in the receptacle or dig a fresh bed in a garden. Most herbs will require partial shade while others need full sunlight. It's important to know which herbs are being grown to adequately prepare.
Appropriate the necessary seeds or cuttings and plant them. The addition of compost or commercial plant products may speed their growth and enhance their health and is especially important if transferring a plant to a new receptacle.
Water plants as appropriate and remove from sunny window sills daily if partial shade is required. In general herbs thrive on sunlight, small amounts of daily watering and moderate temperatures.
Harvest plants as appropriate. Be knowledgeable of blooming signs and don't remove parts of the plant that will prevent it from further growth or renewal. Cure or store herbs as necessary.
