I have a footpath garden and despite bag of soil,newspaper and poop, the sand keeps rising, help!
Sandy soil takes a lot before it develops enough structure to hold on to the inputs you put in.
google 'sheet mulch'
google 'no dig gardening'
take a trip to the stables (randwick race course, or police horses in surry hills)
apply thickly (at least a foot in total, preferably 2)
