Mounting pots on walls, balconies, and roof overhangs also uses vertical space. If your best sun lands on a small area or against a wall, place pots there on a tiered plant stand.
There are also newfangled vertical growing systems modeled after modular systems that support green roofs. Options range from plastic grid systems with angled planting cells (ELT Easy Green
) to products made of metal mesh (McNichols
) to fabric pockets that look like shoe storage systems (Urban Garden Products, Inc
and Plants On Walls
). Just make sure you understand where excess water will drain so that you don't rot out a wall or balcony. Shown:
