Tractor Supply Company Welcomes Jonsered to Its Line-Up

Agreement makes Tractor Supply the exclusive national retailer of Jonsered.

After numerous years of battling with slugs feeding on my garden foliage, I became obsessed with finding a permanent way to defeat them. My persistence eventually paid off when I began concentrating on the “scratchiness” approach. Here’s how it works. (Note: This method requires raised beds.)

First, purchase a common hardware product known as silicon carbide. Its purpose is to sand drywall spackle, and it comes in boxes of 50 sheets — 4 1⁄4 inches wide by 11 1⁄4 inches long — in 80 grit. You’ll also need a box of stainless steel staples and a staple gun. Now, cut the sheets in half lengthwise using a utility knife, then staple them end-to-end to the uppermost sides of your raised beds.

Make sure you purchase silicon carbide sheets that are waterproof — some types are and some aren’t. When applying these sheets, be certain to staple them tightly against the raised bed frames: Do not leave any gaps for slugs to crawl “under” these barrier sheets.

This method has worked magically for me, and I can honestly say not a single slug has crossed these barriers! To make a good thing even better, I only have to replace the silicon carbide sheets every four years.

You could mulch with those spiky fruits from sweet gum trees to impale them!

we always put beer bottles around the vegetable garden, with a splash of beer, the slugs go in, and die, we get rid of the bottles when they are full, so no one drinks em again!
