For a garden to thrive, leave no slug alive
For a garden to thrive, leave no slug alive
I ask you … what
is so offensive about slugs? I’ve got so many fascinating tidbits to tell you
about slugs, but I’m afraid you won’t listen because they are, well,
gross.
However, if the law of the backyard jungle is “know
your enemy,” I just might be able to help when it comes to conquering the slimy
king of the garden. For instance, it’s well known that slugs are easy drunks.
Some people drown slugs by attracting them to beer poured in margarine
containers. OK, but I bet you didn’t know that slugs are cheap drunks! Save
those microbrews for yourself. Oregon State entomologist and slug researcher
Glenn Fisher reports that slugs prefer a light beer 2-to-1 over more expensive
brands. I can see the commercial coming: Slugweiser! Budweiser frogs, move
over.
What else works? Crushed eggshells slice slugs to
pieces. A 5 percent solution of household ammonia in water in a sprayer works,
too. Diatomaceous earth — soft rock composed of the fossilized skeletons of
algae — can be productive but has little effect when it gets wet. So forget that
for spring.
How about making your own slug traps? Slap down
some flat boards, shingles, damp newspaper or even an upside-down cantaloupe
rind. In the morning, check for slugs hiding underneath.
I know some of you use salt and scissors, but
that’s too hard-core for me. And you don’t really want to work that hard, do
you?
With that in mind, I should probably tell you about
the results of the slug track and field trials at Oregon State University.
During these Slug Olympics — no, they are not an officially sanctioned athletic
event — slugs raced for iron phosphate pellets, such as Sluggo and Escar-go!, or
metaldehyde products, such as Corey’s and Deadline.
OSU’s researcher found that while both formulas
worked well, some worked better than others. The metaldehyde compact pellet bait
was more effective, but the iron product was better than no bait at
all.
But consider this: The government lists metaldehyde
as highly toxic to dogs, cats, birds and children. That’s why I stick with iron
phosphate, even if it’s only a close second. After all, when it came to the Slug
Olympics, the contestants were finished as soon as they started.
Now, here’s your gardening “To Do” list for the
week — your mission, if you choose to accept it.
- Spring cleanup. Remove mulch or evergreen boughs
covering the crowns of plants. Cut back seed heads left for winter.
- Plant bare-root roses in the garden, or in pots if
you don’t know where you want to plant them permanently.
- Heel in plants uprooted by frost or pests.
Carefully press the edges of plants back into the ground.
Enjoy!
