Two applications of Pre-Emergent but a yard full of Oxalis weeds.
I’ve purchased 4 products from you so far in 2026. I applied Safeguard 0-0-7 Pre-emergent in early March to my centipede lawn. My square footage in 7,500-8,000. I followed up with Guardian Pre-Emegent in the 4th week of April. I’m now looking at a lawn with far too much yellow wood sorrel growing. I wouldn’t complain if it was near the perimeter of my lawn or near flower beds as I try to avoid spreading too close to those areas. I’m concerned that it’s eveywhere. When I apply your product using my Scott’s Lawn Pro Broadcast spreader I apply at half rates so I can make 2 passes in different directions. The first bag was 50 lbs good for more than my yard needs but used the entire bag since I have in ground irrigation so I can ensure adequate watering. The application of Guardian was 25 lbs which was slightly less product but still sufficient amount for my yard to receive sufficient coverage. I see some evidence of Oxalis wrinkling and turning brown but too much looks unaffected to the point I’m applying a spray herbicide to kill the existing growth, extra work that I did not encounter last year when I bought my fertilizer and herbicide at Lowe’s.
