To make picket-fence herb gardens, purchase a 5-by-8-inch wooden planter box with a bottom seam for drainage, and about 4 dozen wooden plant markers.
Glue plant markers around the outside of the planter with wood glue, lining up the bottoms of the markers with the bottom of the planter.
Paint planter with one coat of white latex paint.
Line each planter with fine gravel or perlite for drainage, then fill with potting soil and two plants.
Settle the potting soil around the plants, and water. We used sage and thyme, but any herb will work.
