Fern gardens are one of the softest and most relaxing gardens you can have and all is you need is regular water so an automatic irrigation system is helpful as well as a smart organic set up. They are a strong plant once established but make sure they are under some sort of canopy so a micro-climate can be established.
Silver Lady ferns are one of the strongest ferns we have in Brisbane so is a must as it is easy to look after. The small button fern is also a favourite. Like most plants they need to be looked after in the establishment period.
