We have lived in our house for 20 years. When we moved in the garden was 80% roses and the rest cottage garden. This equals a lot of hard work. Pruning, watering, bug spray and more pruning. Summers in Adelaide are harsh, with 40ºc + every year. Heat waves go on for weeks. Rain is minimal. I have found a few Australian Native ie hardy plants and bushes and she (the garden) copes very well most Summers. As we get near retirement age we want to travel. This means leaving our garden to fend for itself.
