This will make the grass thrive. Planting the grass on the side of the lawn or garden would be a great idea on the south side. 

Soil – pampas grass is drought-resistant grass as we have talked about earlier so aerate the soil and rake it well to make it lose and make good drainage. You can pull up some of the soil from that part and replace it with sand to have good drainage. This will also ensure the grass grows well.

Timing – this is what we have not talked about yet. Pampas grass starts to grow after the last frost when the heat and light of the sun start to make an effect. So to have good growth and healthy grass, plant it after the last frost in the garden so that the grass will grow rapidly and also have flowers till August.

  • Aerate the soil – After you have selected the seed, the next step is to prepare the soil by aerating it and doing a raking so the soil is loose and has drainage as pampas grass wants soil to develop roots.
  • Sow the seed – sowing the seed is very easy as you just need to put the seed on top of the soil and not cover it up or rake it. Just put the seed on top and water deeply. 
  • Cover it up – if you have birds in your area then they can be a threat to the seeds as they can pick the seeds. To protect the seeds, cover that area with some net or mulch so that the birds can’t pick it up.
  • Watering – keep the soil moist until you see some sprouts coming out from the area as pampas grass needs sunlight and water to germinate. After this you don’t need to worry about watering that much, just watering once a week would suffice the plant.
  • Fertilize – after watering, put some fertilizer to give the seeds some boost to grow. This will make sure that the grass will grow fast and healthy. You can use Miracle-gro fertilizer for this purpose.
