Below are general guidelines for growing herbs. It's probably easier than you thought and there's nothing better than harvesting and cooking with your own home grown produce.
Many herbs can also be grown in pots indoors, so long as they are kept in a light position (e.g. on a windowsill), but beware of them being scorched by the sun through the window!
Most herbs prefer a sunny position, especially the woody types such as thyme, sage and rosemary, although shade for part of the day is a welcome relief to the annual types such as parsley, basil and chervil.
