Converting Lawn to Perennial Bed: Soil Preparation Formula

A gardener asks for general pointers on turning grassy lawn into a perennial bed.

Soil Prep Is Everything

Formula (per 6x6 ft, assuming 2-3" topsoil over clay):

  • 1 bag peat moss (1/2 large bale)
  • 1 bag play sand
  • 1 bag gypsum
  • 1/3 bag Milorganite
  • 1 bag cedar/cypress mulch
  • 3-4 bags manure (horse, chicken best)
  • Rototill 8-10 inches deep.

Then Plant

Remove grass first (sod cutter or smother with cardboard/mulch). Then amend. You'll be amazed at the results.
