David Robson from the University of Illinois Extension says the best results come from moist, richly organic black soil. 伊利诺斯州大学拓展部的 David Robson 称潮湿的，肥沃的有机黑土是最好的选择，

He says that is because the farmer used rich soil to produce the sod, so it might not do well in clay soils. 他说这是因为农民能用肥沃的土壤产出好的草坪，这是黏性土壤所做不到的。
