I got an early start on my garden this year but quickly have been a bit demoralized.  I planted radishes, beets, brussel sprouts, cauliflower, spinach, kale, peas, and broccoli in April and while I got lots of babies, I really only have a few pea plants, a bunch of holey radishes and an odd spinach and kale leaf here and there to show for my efforts.  The culprit is more than just slugs and I haven’t quite sorted out who it is (I think since I have banished the woodchuck it must be a bunny) but the holey radish is of the insect variety.   And I noticed slugs on my Peonies.  Yuck!  I am taking action before they get my babies that have been planting since.

I am testing out one of many organic options for slug control –  and that is the use of copper.  Lowes has rolls of copper flashing that I reason gives me the most options for different methods.   The idea behind the copper is to block access to your plants with the copper.  Slugs and their slimy nastly membraneous bodies do not mix.  When a slug starts to ooze across a clean, corrosion-free piece of copper, a chemical reaction occurs with their slime layer which causes the slug to experience an electric shock. (how satisfying is that!)  I wish there was an equivalent for bunnies.  Any scientist know a substance  that reacts electrically with soft fur? ;)

I’ve got other plans for the extra flashing (I am thinking to experiment with a homemade water feature….more on that later).  To install, I simply cut a strip of the flashing to the length of the my raised beds, removed the sticky backing (though I am not entirely sure that was necessary  and wrapped it over the edge of my beds.   Bonus that they match the new terracotta and copper plant tags that I made earlier this year!

Sluggo is the best option and it’s safe! We lived with succulent eating snails & slugs year round. Lowes should carry it :)

Never had any luck with the copper foil, and really never liked the way it looked in the garden – Sluggo is absolutely the best solution for snails and slugs.

Unfortunately, Sluggo is toxic to soil organisms and eventually kills your soil life. You won’t find that on their label.

And, Sluggo + uses Spinosad which is toxic to honey bees.

I use copper in the form of Slug Shield. Year-after-year with great results.

I say let nature run its course, I don’t agree with using toxic chemicals on plants. Out of interest, i’m assuming using copper kills the slugs – or does is just deter them?
