What do you see in this lawn?
Does the dandelion in the center of the picture bother you? Did you notice that the tips of the blades of grass are a little ragged, indicating that someone needs to sharpen the blade on her lawn mower?
Or did you see how the green the lawn is and jump to the conclusion that it must be a suburban wasteland created by the overuse of lawn chemicals, primarily herbicides and insecticides, in spite of the dandelion that is clearly considered by 99% of all people to be a weed.
Maybe you saw nothing wrong with this picture.
If that was the case, good for you. I see nothing wrong in this picture, except maybe the ragged tips caused by a less than sharp cut with a dull mower blade.
I took this picture in my backyard where no herbicides or insecticides are used on the lawn. It does get some fertilizer in the spring and fall, as do other plants in my garden.
I mow "high", generally not shorter than three inches, and hope that the lawn crowds out the weeds and not vice versa. When I think of it, or when a really big dandelion or other weed really does stick out and grab attention away from the lawn, I dig the weeds out. I do try to keep the mower blades sharp, and will admit that after I took this picture, I realized that it is time to put a little edge on those blades. I do this with a sharpening file as best I can.
I'm not looking for perfection in my lawn, I'm just looking for a sea of green upon which will rest the "islands" of flower borders. Actually, the garden beds and borders are more like continents surrounding the sea of green. On the northern shore of the sea is the Vegetable Garden Cathedral, to the west is The Shrubbery and Plopper's Field, to the east is August Dreams Garden and Woodland Follies, and to the south is Birds' Blanket, the patio, and some yet to be named continents, I mean flower borders near the house.
The lawn, the sea of green, clearly needs its own name, too. I think I'll refer to it as simply The Green Sea.
