I plan to plant carpet grass in my new house n my father in law who is a farmer volunteerd to plan for me n also fix the irrigation system for me. He got his grass from his friend house ( donated by his friend) . I also got few more pieces of japanese grass SOD due to insufficiency.

Pls comment if this way if planting method works? ( photo attached)

1. The general view if the whole land
2. The grass donated by my FIL friend
3. The grass i bought from nursery. May i know pic 2& 3 are the same species of grass? Are these japanese grass?

May i know how fast can these grass grow to cover up the whole land( expose under full sun light n water daily)
