Add 1 tsp. of liquid food coloring to 1 cup of water. Drizzle the colored water onto the soil surrounding the base of a plant. Wait 24 hours for the water to absorb. Apply another identical dose if the color change was not sufficient.
Moss graffiti - mix yogurt, water and live moss in a blender, then paint onto a wall. Moss will grow in the shape of whatever you painted. Just remember to spritz it with water every once in a while to keep it alive.
Galvanized Trough Fairy Garden - I made a mini galvanized trough Fairy Garden inside the larger one! I used an unfinished wood craft house and glued pinecone petals and mini stones onto it. I made a mini birdbath with a bottle cap, some hot glue for water and odds/ends for base. The pond is clear take out lid with green & blue food coloring. I glued small stones around edge.
