Using your custom metal garden marker is easy. First, decide where you want to place the markers in your garden, whether it's indoors or outdoors. Then, write the names of your plants, herbs, or flowers on the markers. If you ordered with mounting holes, you can use nails or screws to attach the markers to a wall or fence. As for maintenance, since it's made of durable metal, it can handle most weather conditions. But if it gets dirty, just use a damp cloth to wipe it clean. Remember, if you didn't order with mounting holes initially but later need them, you can always leave a note at checkout next time and we'll add them for free. Enjoy your organized and personalized garden!
