I used to care a lot about my lawn.
Use to cut it weekly, twice weekly in summer, feed it, weed it and water it with sprinkler system in dry weather.
Looked fantastic.
Nowadays I care a lot less.
Yes, I weed it, feed it, but cut it every fortnight and rarely water it.
This is to say that if you want a great lawn you have to spend a lot of time on it.
Living on the edge of the countryside our garden was levelled and raked 30 years ago and the lawn arrived on the wind.
I cut it maybe every 10 days, it's never had any feed and we don't own a hosepipe.
Our two neighbours on the other hand have had people coming on a regular basis with various treatments over the years.
I think we may have a bit more moss but from a distance all three lawns look the same.
