It's still in the same place
I am going to preach a little about big box stores and seed. Don't do it.
Many times it is old. All of it is low quality with an assumed "price point" attractive to homeowners and their desire for convenience.
It really isn't "cheap" and certainly isn't good seed. It is not a custom product for this climate but a compromise.
Name brands mean nothing. Pennington is among the worst quality.
Weeds, weeds, weeds...the seed at box stores is full of weed seed. Says it right on the label. even tiny % of weed seed is thousands of seeds.
Find a place that sells first quality seed as it's business. I recommend
Southern Seeds in Middlesex NC.
I get their Triple Threat blend, all of the seeds in it were developed in this area for this area and did very well in NC State University turf trials over many years.
It has ZERO% weed seed. Is $75 for 50 lbs. This is MUCH cheaper than the box store seed. Last I looked, Rebel seed was over $45 for a 20lb bag. Rebel Elite was $60
Southern seeds carries chemicals you can't get at Lowes. Tenacity and Barricade chiefly which make crabgrass and weeds a thing of the past.
