Minnesota is about 4" short of its annual rainfall, so we're sort of in a drought. But tonight we had a beautiful storm come through, with crisp cracking lightening and great big drops. I opened my window, put my feet against the wall, and watched the storm blow by. This gave me time to finally sit and think about something that's been bothering me for the last five years. No matter what happens, we never have an "ideal" amount of rain, not for the landscapers or for the farmers.
So: How much rain must fall so that we would *never* have to water our lawns? In other words, what are the ideal conditions for a perfect, natural summer lawn and are they actually achievable? Is it a bit every week? Every two days? What natural amount of rain will keep the grass green and bright? Also: What impact has concrete and asphalt had on lawn water retention? Are grass strips (the area between the sidewalk and the curb) always going to have a harder time finding water than larger swaths of grass? What are the most ecologically friendly grass alternatives? What is the cultural history of grass?
Now is not the time for these questions...
