  • Water, water, water.
  • Can cut the new sod after 2 weeks, under normal conditions.
  • Remember to purchase only clean fill.
  • If the berm is going to receive high foot traffic, then lay a soil backed sod. Soil backed sod holds up better to high foot traffic. It is more expensive per piece and heavier to move.
  • Remember to purchase fresh sod. Does not matter if the soil is peat or soil. Peat sod is lighter in weight and usually less expensive than soil backed sod.
  • Rolling the fill makes adding the topsoil easier, but not necessary.
  • Remember to roll the topsoil. It should look smooth.
  • Do not fertilize or use weed control in the first year. However, when laying the sod, a growth hormone can be applied to the topsoil prior to laying the soil. This is an amazing help to quickly establish the sod roots.
