hi there , the only way to get rid of mares tail is too squash the plat everytime it shows up , dont cut it off , squash it and then round up the little * ,
mares tail is waxy and is water proof , thats why its been aroud for 2 million years , squash it and round up is the only way , squash it and round up with in 10 minutes ,
even then it can take a full year to get rid of it , keep smiling ,
