There are some beautiful topiary sculptures out there, some as large and intricate as this life-size T-rex topiary at the Botanical Gardens in Buffalo, New York. But most balcony garden topiaries shouldn't be intricate, and especially not large, because space is at a premium in the balcony garden.
Because space is at such a premium in the apartment balcony garden, you will need to clear up any clutter you have on your balcony. You can always maximize space by planting vertically (which you can achieve with this DIY plant shelf), but there may be some other items in your balcony garden that you can do without.
Succulent plants are unique-looking plants with lots of character, especially for Southwestern-style gardens. These easy plants do well in hot, dry climates, and they go well with the look of many Southwestern-style buildings that have stucco walls and Spanish Mission-style tiles.
A plant container can be pretty much any object that holds potting soil and that can have drainage holes drilled into it. You no doubt have seen photos of (or in real life) plants growing out of an old boot. Even old bathtubs or troughs can be used as plant containers.
