I can't get parsley to grow in my garden for love nor money, somebody told me you have to ask the devil to grow it! Plants such as mints are best kept in big tubs else they'll spread like wildfire. Basil I grow in pots in the greenhouse, it keeps the blackfly away from the tomatoes. The 'woodier' herbs such as thyme, marjoram (oregano) and rosemary should grow into nice bushy plants, if you want it to grow up pinch out the sides, and vice-versa.
This is a brilliant website for tips - what to grow, where to grow it, what to use it for and seeds too - what this lady doesn't know isn't worth knowing!
