At this time of year, the lawns of the Chicago area are slowly emerging. Some residents are already mowing to address one key feature of an acceptable suburban lawn: it must be even.
You can have a green, full, and weed-free lawn but it is not complete if it is uneven. This primarily has to do with grass height. The acceptable lawn is uniform. The grass looks like a flat surface. It does not have to look exactly like a golf fairway or green but the idea is the same. A lawn with weird dips and rises can also make it look uneven compared to a flat surface or a continually sloping area.
In the spring, the grass may be particularly uneven. Some of it is due to the activity of dogs. Some of it has to do with all the rain and moisture the grass has had. The growth might be different across a lawn, meaning mowing would lower the height of the grass in some spots and not be needed elsewhere.
This time will pass as more growth, higher temperatures, and regular mowing evens out lawns. For those who like lawns that do not have a uniform height, now is the time to enjoy.
