A paddock workers best friend in the paddock is mulch. Obviously that refers to inatimate objects and not to the Resposible Adult who is this paddock workers best friend in regard to humans. Mulch helps to retain moisture in the soil and to keep that harsh Oz sun from heating and baking the soil. It brings worms and micro organisims into the garden and eventually breaks down and becomes humus in the soil. So having established an area in front of the groovy pad for a garden, it is time to mulch and plant. The cheapest mulch is called forest blend. Forest blend is the chipped remains of trees that some other person wanted removed. If I ever have a tree removed, then the resulting forest blend stays on the paddock, but some people actually want it removed! So, you just phone tree removers and ask them to bring you someone elses unwanted mulch.
Having had your bloody big pile of mulch delivered, it then needs to be moved and spread on your garden beds. The easiest way to move this, or any other big pile of stuff is to lay your barrow on a low angle and start raking the stuff in. You can get a fair bit in this way without having touched a shovel. Then stand your barrow up and shovel until absolutely full. Obviously, if you were shifting somethin heavier, say gravel, then half a barrow load is probably heavy enough. But with mulch, you should go really full so as to save a few trips.
