Went to the Nambour Garden Expo at the weekend and have decided to plant the embankment out with a "Good Bug Mix" - a mixture of perenial flowering and other plants that attract and support populations of bugs that are preditors to the pests that attack our fruit trees at the bottom of the embankment. That way I can let it go a 'little bit wild' and it will look pretty and do a benificial job with minimal attention.
