In fact, larger, more mature potted plants might make more sense for balcony gardens than small pots; having just a few different plants in your balcony garden, each of them well suited to the particular light and wind conditions, makes for much easier maintenance. And the look is a bit more refined than a motley collection of pots (which can, of course, be beautiful, but sometimes results in a cluttered look).
Of course, some balconies are just too small for mature plants; not all of us have the luxury of balcony space shown in the garden above (designed by the U.K.-based Paperbark Garden Design). Furthermore, weight and watering requirements may make mature plantings difficult on some apartment building balconies.
What do you think? Are you growing large, mature plants on your balcony? Please share!
