Kenny Barrett's no stranger to dirt and a few plants. The local creative and one of the founders of the Roosevelt Growhouse and the GROWop in downtown Phoenix spends most of his time tending to the boutique/urban garden's produce and managing Valley of the Sunflowers, the two-acre lot-revitalization project across the street. He also has an eye for what looks good (especially in hipstamatic).
Materials:
6. Add the soil mixture to your container. The soil should be one part potting soil and two parts sand or one part sand to one part shredded peat moss.
7. Starting with your largest plants, set each plant inside your terrarium until you find a layout you like. (Hint: Create a funnel with a piece of paper to "drop" the plants into your jar so that the sides don't get dirty...).
8. Funnel or spoon soil into the jar around the plants and softly press the soil around each plant to make sure they stay in place and can root themselves in the terrarium.
9. Add sand, decorations, found objects with long pliers. Use a paintbrush or tweezers to dust off any dirt or sand that might be covering your decorations or that's stuck to the side of the jar.
10. Close the jar and find a good sunny location, preferably near either a window with a southern or western exposure, for your terrarium. It is important that the plants get enough light during the day.
11. Water your terrarium only when the soil is dry at least 1-inch down.
