I have been maintaining 2 Zosia lawns for several years. Yet to get the fert part of the maintenance on this yard down yet. I have gone to Lesco to buy fert just for this yard. I put down what the suggest with little or no results. What do you guys put down on Zosia to get it to green up. The guys at lesco told me that this time of year (spring/early summer) that zosia can handle all the nitrogen it can get. I thought in that case I can put down Urea??
