Soil Amendments
Q.

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

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?

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:
