Soil amendment, was Planting Lilies

For more background on soil amendment using sand, google “soil triangle”.  You can turn clay loam into loam or sandy loam, but there isn’t much you can do with clay, except bury it with topsoil, or haul it away and replace it with topsoil.  My rule of thumb is this:  if your heavy native soil grows a good crop of weeds and grass, it can probably be amended with sand to produce sandy loam soil.  After that, you can achieve nirvana by raking the soil into raised beds.  My experience is that nearly everything will grow to perfection in raised beds of sandy loam soil with mulch.  But they don’t do much for garden esthetics, sadly.
