Weeding my
asparagus patch this weekend was a joy. Weed a foot, celebrate with a spear,
weed another foot, munch some more. Have you ever had asparagus fresh from the
ground; raw, crunchy, juicy, and sweet? It was a discovery for me that
asparagus could be so delicious. It was more reminiscent of fresh ‘mange-tout’ sweet
peas than it was of the steamed spears traditionally laid out sparingly and
artistically next to a fancy piece of animal flesh. I ate a dozen out there in
the field, slowly burning the skin on the back of my neck.
Once these weeds are out of the way, this asparagus spear is my reward! |
As I pulled
the weeds up through the mulch I was surprised at the number of earthworms at
work in there. When I was digging the holes for my new plants this spring I saw
very few earthworms, yet here beneath an inch of grass they were having a huge
party on the surface of the earth.
Everyone
knows worms are meant to be a sign of a healthy soil. I wanted to take a moment
of your time to talk about what it is these fleshy noodles actually do.
Worms live
in the ground, of course. Like rodents, they like to keep a door to the outside
world in their domicile. From this hole they reach out and grab at decaying
organic matter. You can see evidence of this in fields where debris is left in
the fall. It looks like many consecutive circles, each circle being the territory
around a worm’s hole.
They eat
this organic matter and defecate in their hole, deeper in the soil. This way nutrients
are spread throughout the soil profile. This organic matter, now worm casts,
contains nutrients that are more easily available to the plants thanks to Mr. Worm’s
digestion.
The tunnels
created by the worms also have positive effects. They aerate the soil, and create
conditions for better drainage and water infiltration. The channels also provide an easy avenue in which
plant roots can travel deeper in the soil to find further sources of water. Even
their wee, noble bodies decompose and provide nitrogen for the plants. A
healthy population of earthworms can actually build topsoil, by how much seems
to vary from one study to another. This is excellent news for me on my site,
where the topsoil is a mere foot before reaching pure bedrock.
I will end
on a darker note. The earthworm is not native to Canada. It appears its
presence
is having a drastic impact on the ecology of our old growth forests. National parks advise people to avoid dumping left over earthworms from fishing trips in the forest. Take them home, feed them to your dog, just don’t empty that container (even if it is just dirt, they might have laid eggs in there!) in our forests.

Have a
lovely week, I wish you good health and happiness!
