## Customer Reviews

### ⭐⭐⭐⭐⭐ Appears to work
*by J***S on June 10, 2025*

Seems to be an organic dandelion killer that works. Make sure you saturate the dandelion.

### ⭐ Did not meet expectations
*by C***R on June 10, 2025*

Did not work in the bootheel of Missouri! Barely burned the leaves of several weeds.I bought this after seeing it on The Garden Answer you tube video. She was trying it out too.

### ⭐⭐⭐⭐⭐ Green lawn…Not green and yellow!
*by A***R on May 11, 2025*

Best way to get rid of dandelions! Does not kill grass. I used to get dandelions out with a weed prong. This was very backbreaking work and if any of the root was left in the ground, the weed would regrow again. I used this weed killing product this spring and yard looks fantastic… No dandelions!
