Marcus chose Watersaver Gardens because they can cope with the intense heat generated by the concrete and full sun on his rooftop deck in Newfarm. Getting the soil and chip up there was a major issue but with some strong volunteers and expert assistance from Roman (see http://spurtopia.blogspot.com.au) we got the job done ahead of schedule.
Instead of trying to keep plants alive by watering every day Marcus now only has to check the water level via the entry pipes once a month.
