Hi Sparkles, and welcome to the board. Be prepared to fail with some seeds - everyone does, even though they may not admit it!
Getting a couple of books out of your local library, and reading the instructions on the seed packet are the starting points for you, as well as coming here. You will notice that the instructions on a lot of different seed packets are more or less the same, e.g 'sow in a fertile, well-drained soil' (you may think this is a statement of the obvious, but think about it), watering instructions, and planting depth, which you should take literally - to a seed, a quarter of an inch is not the same as an inch. RHS website is good for info about growing all sorts of flowers.
