I have a 8' x 36' area of kikuyugrass (and few survivors of St. Augustine) in the front (side) of my lawn that I'd like to remove without using any glyphosate based product. Since reading around, I have several options in order to preserve the soil and not leave behind anything harmful.
The first would be solarization (warm weather coming right about now). Do I use clear or black plastic? Where would I get a large enough sheet?
Second would be several layers of wet newspaper. I've never tried this before but I can think of a few issues - 1) the newspaper possibly not holding down completely 2) it could be a potential eyesore - HOA? 3) with the warmer weather coming now, the method might not decompose the kikuyugrass properly and/or it'll just sprout right back up with any remaining roots underneath, as soon as the newspaper layer is removed.
I considered renting a sod cutter, but it most likely would not take care of kikuyugrass' deep root system.
