Perth, Western Australia
The soil where Kaz and Paul live is pure sand Water simply soaks through and disappears In order to change this Derek mixed clay with manure and washing detergent (the sort that's compatible with septic systems) to make a mixuture where the water will hold and nourish the plant. Then the planting and finally the dri irrigation system
Sandra Crowley nee McIntosh donated quite a few plants from her garden as she's a real green thumb Thanks Sandra
See album Kaz'...
