Until a plant becomes firmly established, it is often good to mark where it is. I use flat river rocks to mark my newly planted mints, with a piece of driftwood in front of the rock so I know where to look for new growth in the spring.

I absolutely LOVE this! I always put rocks around my baby plants anyway so that they don't get frozen up and out of the soil during winter, so this is perfect.
You don't kick walls down, you pull the nails out and let them fall.

I like marking where to watch for new growth, also, although I often use small sticks pushed straight down into the ground... an upright stick has that "done on purpose" look that catches my eye. Useful to know where to expect new growth of a valued plant during spring weeding festivities!
