Magnets help, but they’re not foolproof, especially if you’ve got mixed metals or the nails are buried in grass.
That’s spot on. Even with a rolling magnet, I still find strays months later—usually after a mower finds them first. One thing I’ve noticed is that nail heads can sink just below the soil line, especially after rain or foot traffic, making them almost invisible. I agree screws are easier to spot, but sometimes the job just calls for nails. I always recommend a second sweep a week later—surprising how many turn up after things settle.

Couldn’t agree more. I’ve lost count of how many times I’ve thought the yard was clear, only to find another nail after a heavy rain or when the grass gets mowed. Sometimes I’ll even use a leaf blower to push the grass around before running the magnet again—seems to help bring hidden stuff to the surface. It’s wild how those little things can disappear right in front of you.
I’m right there with you—it’s like those nails have a mind of their own. What’s worked for me is going slow with the magnet, almost dragging it through the grass instead of rolling. I’ve also tried watering the area lightly before a sweep, just enough to settle the dust but not make mud. Seems to help the nails stand out a bit more. Still, I always seem to find one more weeks later...
Dragging the magnet works, but honestly, I just skip the water step. For me, it seems like watering makes the nails sink a bit more, especially if the ground’s soft. I just stick to a slow sweep after mowing—less grass for stuff to hide in. Still miss a few every time, though...
I get what you mean about watering—on softer soil, it does seem like the nails just disappear. I actually do the water step, but only if the ground’s really dry and hard. Otherwise, like you said, it’s just a mess.
That’s smart, though. My trick is an old broom to push the grass down first, then go over with the magnet. Still end up finding random nails months later... but at least it cuts down on tire punctures.“I just stick to a slow sweep after mowing—less grass for stuff to hide in.”
