Lawn - new grass turning yellow
End of May, had a new porch/walk put in and part of the front lawn was destroyed in the process (about 50' 10'). Put down top soil, Penn State Mix seed, then mushroom manure. It was a real battle because just when seeds started to sprout (about a week), we had extreme thunder storms and washed a lot of the mushroom manure, seeds and sprouts down the sloped lawn in waves. Did reseed, and it came in fairly nice, but I will still have to patch bare spots from the storms, now in the fall. When the lawn came in, it had a lot of some broadleaf weeds and barnyard grass. Local garden store said to use >>>Weed-B-Gone MAX
Hello and Thanks for using the Ask an Expert SystemBefore you start applying weed killers to your new lawn I recommend that you take a look at Penn State Extension’s publication “Weed Management in Turf” it is available for free download at http://pubs.cas.psu.edu/FreePubs/pdfs/uc189.pdf
In addition Penn State Extension has a thorough and detailed source of information on all aspects of lawn care on an online web site “Home Lawns” You can access this site at http://plantscience.psu.edu/research/centers/turf/extension/home-lawnsIf you have additional questions I suggest that you call Allegheny County Penn State Master Gardeners.
