This has been the difference between thistle, grass, and creepers overgrowing my landscaping and staying five steps ahead of the weeds. It obviously doesn't kill the whole weed, but I've been able to knock down the new growth again and again in a way I couldn't if I were weeding by hand. After enough applications, I'm finding that the rhizomes of my main problem (thistle) get starved out and stop regrowing. Way better than a torch.
Only challenge is spring growth, when weeds start growing but temperatures are still below 50 degrees, but in direct sun, this works so fast. Very very pleased with the results.
Thanks for sharing your success with Finalsan:registered:! We’re thrilled it’s helping you stay ahead of stubborn thistle and other weeds. For that cool early-spring window, try spraying in midday sun—just a few extra degrees kick the fatty acids into gear faster. Need more tips? Happy weeding!

So far I am pleased with this product. I was looking for an alternative to round up to spray on my backyard. Will be reseeding the area with native flower seeds. After 1 day the grass and dandelions are dead. Need to order more!

Works Great
So far this has worked better than Glyphosate on our gravel driveway with weeds like Yellow Clover, White Top and even Russian Knapweed before flowering. Spraying was done on regrowth, on a hot summer day about a month after mowing earlier in the season. The shipping was fast with excellent packaging I especially appreciate the tape on the container caps to prevent leaks.
