Q&As

1 - 2 of 2 Questions

Q: Will this work as a pre emergent when applied in February?

a year ago
1 Answer
  • A: When using BioAdvanced products, for best results, we do recommend waiting until early Spring to apply. It is important that the lawn is completely green and actively growing, and that temperatures are in the range of 50 to 90 degrees, even overnight, at the time of your application. -Madison

Easy to apply and those pesky weeds can officially be gone!

5 days ago
So far I am really liking this! Application was simple and the packaging makes it easy to use, and there wasn't an overwhelming odor. We have Southern grass and those pesky weeds are always coming through. I love how this kills the weeds and prevents new ones from popping up! Anything that means less time fighting my lawn and spending more time enjoying my yard is a win for me! Pesky Weeds BeGone!!

Will use again beginning of summer

This lawn weed killer does a solid job overall. The packaging is sturdy and thankfully doesn’t leak, even after being stored in my garage for weeks. The label instructions are clear step by step with measurements that are easy to follow, so dilution feels foolproof. In terms of value is overall a great take.

Effective

I seriously havent loved a weed killer before. But here we are!! This works well in the south Texas summer heat. It is so effective half of my yard is coming back to life in the beat way possible. I had so much crab grass and this helped rid of it. The best part it seemed to get rid of the crab grass overnight! So quickly! My grass is coming back even thicker too which is such a plus! If only my hair would be this voluminous

Thank you for taking the time to share your thoughts on BioAdvanced Season Long Lawn Weed Killer Plus Preventer for Southern Lawns. In some cases, especially later in the season, weeds may be more established and may need a second application. Thank you for your review.
