Central Florida (Zone 9a) I recycle, reuse, repurpose!
Have you ever thought about using those big deep plastic tubs that TS sells for horses to drink out of? Would that be something you could use to have a raised bed effect, plus you can grow a lot of stuff in those. My friend Barb has a bunch of them and grows veg and herbs in them and they look terrific. Just a thought. You could use some of that free mulch to fill one and top it off with a good soil mix. I love her garden and it's so easy to walk around the tubs and pick tomatoes or whatever.
