Easy-care succulents, such as sedums, echeverias, crassulas, and more, are all the rage. To display your faves, punch three holes in the bottom of a boot tray with a hammer and large nail. Fill the tray about three-fourths full with a premoistened mix of 3 parts potting soil and 1 part sand. Position two or three bricks in the center. Plant an assortment of succulents shoulder to shoulder around them. Fill crevices with Scotch or Irish moss, which thrives in well-drained soil in sun or part shade, as do succulents. Top the bricks with pumpkins. Water when the soil is dry to the touch. This display will withstand light freezing temperatures, so it's okay to keep it outdoors.
