Stone Herb Markers use a white Sharpie pen. I'm about to plant my herb garden. What a good idea.
Use an old pallet to make a vertical herb garden! Cheap, easy and beautiful! Just make sure to find out how the pallet was treated so you're not planting in harmful chemicals! And- u can write the name of the herbs on the wood!
Training Wheels: Bike wheel trellis with espalier apple tree. Maybe passionfruit vine
