Good point and well put I get the impression that turf is an evil of the sustainable philosophy as well. I don't see grass as a 'monoculture' rather it is a 'colony'. The same as any bacteria will colonize and dominant an area, if given half a chance, grass does the same thing. The right grass in the right place will grow to the exclusion of all else once established. I am glad that Kiril and Tom are going to team up and simplify CTs etc. for the benefit of the forum, but I agree with Kiril's earlier statement that the goal is for our lawns to become self sustaining. I know that they can be, because as I have said before the best lawns in rural Wisconsin are not watered, fertilized, aerated, weeded with 2,4d, or mowed at regular intervals at the proper height. There is a long tradition of using the heavy iron rake in the spring however. The problem lawn care people face is hybrid grasses for color, too much water for lushness, too much fertilizer to be safe, then we start killing everything in the soil. Good for business, but terrible for lawns. The first step in organic switch over is to stop fertilizing in the spring rather just topdress with compost. Inexpensive, safe and simple.
