Is homemade weedkiller cheaper than commercial products?
The answer here is also NO as the price the price of vinegar alone is about 64p a litre without the salt and washing up liquid. This compares to 25p max per litre of ready to use glyphosate at a rate of 10ml concentrate to 1 litre of water or 50p max per litre of ready to use glyphosate at a rate of 20ml concentrate to 1 litre of water.
