I have a massive herb garden all growing in terra cotta pots - big ones 75cms or so high - in full sun against a brick wall arranged on a terraced wrought iron stand and it looks like the hanging gardens of Babylon! Even have a lime tree in a giant pot (important for my husband's Coronas).

Herbs seem to like to get hot, dry out, get hot , dry out etc - rather like the Mediterranean climate I think, so daily watering of the pots - particularly in Summer, is vital.

Another good thing about pots, particularly with things like mint - it keeps them where you put them, as opposed to taking over your lawn or whaetever when you're not looking!

Marina.
