I have only been watering selected plants with it ie not my 'best' plants.
Is it toxic to plants does anyone know? |
Shouldn't be toxic in such dilution. Are you in a hard water area? Fizzing suggests some form of carbonate reacting with the residual acid, unless you are using a galvanised watering can, in which case there might be a reaction you could do without, but still unlikely to harm plants if well diluted (more likely to 'eat' the watering can).
Is that one of those plastic cubes in a frame?
