It is REALLY easy to grow most herbs, they love a sunny window!
First you have to buy the herbs you like to cook with
This depends on your own style of course! If you let us know what types of food you like to eat we can help out.
Then you need to look at your window area and see what kind of a pot will fit. Some people have space for big, round pots. Other people need thin, rectangular pots. If you post a photo of your area we can help with that too.
Then you plant the seeds according to the instructions! I'm growing lots of herbs right now and will be posting photos. Mine will all be outside for now though
