here's an idea for a low maintenance, small space, winter or summer garden inside or out.
you will need:
an old ladder
potting mix & sand
plastic to line cups
i used a variety of succulent cuttings from the garden on our deck. i lined thrifted teacups with plastic, added a mixture of potting mix and sand. planted the cuttings and covered the soil with tiny shells. the teapots are filled with water.
