“I’m not sure exactly what type of weed is as I’m not familiar with what is native to that area of Canada. Could potentially be wild violet, but I’m not certain. As for why that area isn’t growing the same, it could be a number of things. It could just be that that area has less nutrients. The soil make up could be different and doesn’t hold water/dries out faster than the other areas. Depending on seed type, it could be getting too much/too little sun depending on how the sun casts down on your”

“I’m in zone 7a/6b (St Louis MO) and just moved into a new house. I can’t tell if this is Bermuda grass or something else. When I google image search Bermuda grass it doesn’t look like what I have. Lots of big fluffy patches with stolons and lifts pretty easily. There are clumps of this all over the front yard that I want gone. I come from TTTF that did extremely well and want to do the same at my new house. Any help with identifying and suggestions on treating this? This stuff is probably 50% of”
“I'm in BC so won't have exact options as you. But I got this seed from Gardenworks, a local nursery, and this is a black label blend made for them that comes out of the Willamette Valley in Oregon. So I'm sure you could find a local supplier with the same blend or something very similar. I tend to avoid influencer brands and focus more on regional gardener knowledge. Everyone's climate is different so there's no one size fits all approach, imo.”

The greener pic is what is covering most of the area in large patches. About two weeks ago I sprayed it with glyphosate. It was a 41% solution diluted to 5-6 oz in a one gallon sprayer.
