i have suggested to my stepson( in the chicago suburb areas) where he mows large hoas to try using embark around the areas he weedeats and edges. as well as using it around the banks of ponds. i have never used this product but had thought about it many years ago. this would save labor,fuel and wear and tear on equipment. sounds like a win win situation if it works properly. i know there are variables that effect its performance. also after trimming landscape ornamentals this could be used to eliminate followup of trimming new growth. what has been your experience and is it economical especially with the high fuel prices?
