i was wondering why what new grass is lacking that makes it give off a yellow tint? i applied fertilizer with plenty of nitrogen to a new area and it still looks the same. is it just becoming established, and this is how it looks until it is fully growing in about a year? or is it lacking something? i also noticed in the same neighborhood (newer development, poor soil) that many of lawns are looking the same too. it isn't rust, but looks like the grass is lacking something.
