I’ve heard the vinegar/Epsom salts/detergent weed killer leaves the soil sterile. Is this true? Is there a better combo?

Question

I have a yard full of London rocket. I refuse to use glyphosate because the bees love the small yellow flowers. But I have been told that the vinegar/Epsom salts/dish detergent concoction I was going to use leaves salts in the soil that will leave it sterile indefinitely. Is this true? Is there a combination of things I can spray over the yard that will not harm the soil or pollinators?

Answer 1

That combo is neither safe nor effective. And it can destroy good things in the soil like earthworms and soil microbes. Here is more information:
