Is Bicarbonate Soda or Potassium Sulfate environmentally safe?
As safe as it comes. Of course lets be honest, if you dumped a whole bag of bicarbonate on a plant, it will die. Plants around a remodeling job should be protected and you will need to wash an area down with water during the clean up process. As explained earlier, for heavy concentrates, you may need to add vinegar to the water as a form of neutralizer. The environment is completely safe, including the waterways and your clients grass and plants. Mosquitoes and their larva seem to be affected by bicarbonate soda, but that is the only insect that appears to be affected.
