Prepare the bed (remove weeds and dead vegetation)
Decide if soil will be amended with Sheet Mulching (a more passive tactic that takes more time to see soil restoration benefits) or Soil Restoration (an active tactic that more quickly restores damaged soils and incorporates organic material into compacted soils to allow for quick replanting)
For sheet mulching, see guidance below under Lawn replacement
If restoring soils please follow steps below
Till in compost (add 3" compost and till 8" deep into the existing soil)
Avoid compaction
For detailed instructions see the Restoring & Amending Soil pdf below
Install native plants
Mulch bed if needed
