Add portable green space to your patio using galvanized metal trash cans and casters.Brian Patrick Flynn, Decor Demon
Select a combination of tall, medium and low metal trash bins. Keep in mind that groupings work best in odd numbers.
Use a drill and drill bit to add about 5 holes in the bottom of the trash can to allow for drainage.
Measure proper spacing for casters with tape measure, then add mark with marker. Drill holes, then attach casters with bolts and screws. For reinforcement of extra large trash cans, attach a strip of pre-cut, pressure-treated lumber to bottom before attaching casters.
Fill trash can approximately 3/4 full, using empty 2-liter bottles (Image 1). Next, top off the can using potting soil (Image 2).
Place tall plants toward the back of the containers, then fill in center with low, bushy plants. Fill in the edges with flowering and cascading plants.
