A force multiplier
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!

I put some seed down on May 29 and am starting to see some come up! I was really impressed with Brandon's expertise and help with my questions about how much to buy, when to plant, etc. I plan on putting more seed down in the fall, to give my lawn a boost before winter.
