Instructions

    • 1

      Add a thin layer of pebbles or gravel to the bottom of your terrarium.

    • 2

      Add potting soil to your terrarium until it reaches about halfway up the height of your terrarium.

    • 3

      Plant your cacti or succulents into the potting soil. You can add one plant or a few in each terrarium.

    • 4

      You can cover the top of the soil with decorative pebbles for an added stylistic touch.

    • 5

      Store the terrarium in an area that receives a moderate amount of sunlight. If your plants begin looking washed out or faded, then they're receiving too much light.

    • 6

      Check the water level by sticking your fingers into the soil every day or so. If the soil is very dry, add a little water. If the soil feels moist to the touch, leave the plants alone for another day.

    • 7

      Add one part fertilizer to four parts water in a watering can. Mix the solution. Water your plants with this instead of plain water once per week.
