Wash the glass container and dry completely. Create a one-inch layer of stones on the bottom of the jar,then add a half-inch of charcoal or gravel. (I thought I was being savvy in skipping this step because I didn’t want to buy any, but it turns out the soil will slip down and cover up the bottom rocks if you don’t have this layer). Spoon in a two- to three-inch layer of potting soil, piling soil higher on one side to make plants visible from a side view. Dig small holes for the roots. Take plants out of their pots, remove extra soil from the roots, and trim damaged leaves. While the roots are still moist, place the plants in the holes and pat soil over the roots. Place taller plants in the back. Dampen the soil but do not overwater. Decorate with pretty rocks, animal figurines, or a garden gnome. Place in indirect sunlight and add water when your terrarium gets dry.
