When creating your own home herb garden, there are many options available to you, I have created this list of tips just to simplify the process if you have no idea where to start, or are suffering from information overload!
Choose 3 herbs to begin with, you can buy a set of three small pots in a shared tray that is small enough to fit on a window ledge and looks very attractive. You can choose to grow from seed or buy small potted herbs. These would be very handy for cooking with if placed in the kitchen, try to make sure they are in a position to get plenty of sun.
Do some research on the herbs you have chosen and consider whether they will stay indoors or be planted outside. If you choose to plant them outside (when they are sufficiently established of course), I would advise to plant in a pot on the patio in the first instance, this will allow you to move the herb easily to the most beneficial location (with regard to sunshine) for it to flourish.
As you move herbs outdoors (or maybe to another location in the home) you can then start growing another herb in the vacant pot, thus building your collection and learning about each one gradually.
As your knowledge increases, you will be in a much better position to design an outdoor herb garden, which herbs will thrive in which type of soil and which need the most sunshine etc. A word of warning from personal experience here: if you are growing mint, I would keep it in its own pot or container -- mint completely overwhelmed the rest of my herbs and ran riot in my first attempt at a home herb garden outdoors!
To preserve your herbs for later use, you can dry them, freeze them or preserve them in salt or vinegar. Freezing is probably the simplest way initially, wash and chop into inch long segments, freeze laid out flat on greaseproof paper and when frozen you can put them into a sealable bag, and a label may be a good idea for identification, especially if you store many herbs in the freezer!
Enjoy your herbs, be proud of them, use them in recipes and enhance the flavour and aroma of the dishes you create. It is very satisfying to know you have grown them yourself and that they are natural, organic and chemical free.
You may also want to look into using herbs for medicinal purposes, they have been used in natural remedies for centuries, for example using lavender to aid sleep. Herbal teas are also very popular these days, for example chamomile tea, peppermint tea etc.
