I am a complete newbie and clueless when it comes to gardening. If i want to start fresh this year and plant a bunch of flowers, what do I need to put down first? We had some reddish wood chips last year and DH has take a bunch out and then layed some soil on top. My BIL suggested we put some mulch on top of that. When you start planting every year what do you put down before you plant any flowers?
