With careful planning, research, and proper plant choice, it is possible to enjoy gardening on balconies. Determining if the balcony can withstand the weight of containers, soil, and water is the most important factor. Check with the building manager for restrictions and weight limits before adding more than a few containers.
Gardening on a high-rise balcony offers the added challenges of strong winds and neighbouring buildings that can cast impenetrable shade. The light and temperature conditions on a balcony are dependent on the direction it is facing and on the height and proximity of the surrounding buildings. South-east and south-west locations are the best. The east-facing will have the softer sunlight of the morning, while the west-facing will have afternoon and evening sun as well as a greater exposure to incoming storms and rain. A south-facing balcony will provide the best sunlight (along with excessive heat) while a north-facing balcony will always be in the shade.
