Last summer my neighbor had some exta fescue sod that wasn’t needed for there new lawn that had been, tilled, layer with dirt and finally sod added. I had recently spayed my yard to get rid of a yard 50 percent weeds ( two weeks prior) so I had a lot of bare spots. I took the extra sod, about 300 sq ft and laid it directly over my current grass (side of home) even used small remnants around tree roots that I thought would never take. I watered the sod daily for two weeks, went to watering every other day, then every three days. Laid down fertilizer for new sod and The result is my yard is beautiful! I ended up purchasing an additional 1,000 sq foot and did the same to my back yard. I like to note I am a female, that has never ever done yard work. I have the best looking yard in the neighborhood, golf course, soccer field, baseball field these are references to what my yard looks like.
