We went to hardware shops several times and Steven built a new sprinkler system.
After we raked the yard to balance it out, we packed it down with a rental lawn roller. Steven is putting water into the lawn roller on the up-right pic.
Then we spread starter fertilizer. One of our neighbor gave it to us and lent us this spreader. They are so nice!!!
Not only that the neighbor helped us to install the sod(down-left pic)!! We used 75 rolls of sod. Looked like roll cakes or sushi rolls...anyone hungry? We laid them in a staggered pattern like laying bricks.
Wow! After a few hours, we got a nice green lawn!!! Steven studied about lawns, designed the sprinkler systems and we did it in a month total. Now we can have a backyard party!!
