Wash the rocks and dry them thoroughly. It may be necessary to let them sit for an hour or so as rocks are porous and can absorb water.
Which rocks you use with depend on what you have growing in your garden. For example, you will need a longer or larger rock for “marjoram” than you will for “kale” as there are more letters to fit on the rock. You can use a piece of paper to map out what rocks will get what names.
Paint the rocks in desired colors. For the longest life of your plant markers, it’s important to allow adequate drying time; allow at least 1 hour between coats. Some colors may need more coats than others in order to cover.
Once your rocks are painted and dry, use a black paint pen or Sharpie marker to write the names of your plants on each rock.
To decorate, use the handle end of a large craft paintbrush to dot on various spots in different colors. Use a smaller paintbrush handle to add smaller spots.
Finally, use the tip of a pencil or a toothpick to add tiny white dots to the center of the larger dots. Allow the rocks to dry for 2-3 hours.
Apply a clear coat and allow them to dry overnight.
