How much salt is too much salt for plants? Slugs have been invading my garden beds in masses recently and I got a bit too vindictive. I grabbed some salt and started sprinkling it along the edges of my beds and around plants to deter the pests. I always sprinkled the salt well outside of the length of each plant’s “canopy” (trying to think of the word here). I never put salt at any bases or under any “canopies.” By the time I reached my front door to go back inside I realized that I had used regular salt and not epsom salt! Now I am panicking! I ran back out to see what I might be able to do and I was only able to find a few pieces of salt here and there but otherwise it was not so much salt that I was able to find it on top of the 4” of dark brown mulch so that I could try and do something about it. So I went to researching and am reading that very little salt is needed to ruin soil. Have I ruined all of my garden beds and killed all of my precious plants for good?! I can not NOT obsess about this.
