Irregular lawn growth and color
I am very frustrated... We are in a new house, last summer was our first. I had the same issue last year and am trying to figure it out this season. First, I have two dogs, so take that into consideration, but as you will see, I do not think they are the main culprit here. My back yard is very irregular in its growth with lush green patches that grown dense with the most perfect looking grass I have ever seen that grows much faster than the rest, and areas that are much less green with some straw colors mixed in that does not seem to grow much if at all to the point I can never really see my mower path in those areas. These areas can start and stop on a dime, not gradually, so they stand out quite dramatically as islands in the lawn and can be 5-10 inches in diameter or several feet around. There are also a few dead patches here and there which I expect are from the dogs, but surrounding those dead patches are some of the most lush areas of green grass; I have read that dog urine if it doesn't kill can actually boost growth with the salts in the urine, is this true? The more heavily traveled areas are some of the slowest and least green, but areas that are not heavily traveled are also much less green than the dense patches and do not seem to grow much if at all. I expected compaction might be an issue and that aeration may be the solution but I also read many posts that it is not necessary in most cases and could be detrimental... So I am confused. My biggest question are why I have these beautiful patches surrounded by grass that is mediocre at best. Thanks for any insight.
