Since worms are natural decomposers of organic matter, adding some not fully finished compost should attract them naturally. Are you sure they are not present already?

And skip the peat.......likely not needed at all.

It was a pretty big project, and we never see them in the soil when digging after 4 years. Here's a picture taken during construction to give you a better idea.

The photo would indicate you are seriously lacking in organic matter. Provide it and they will come :-))

Adding worms won't do anything if you don't give them any reason to stick around. As said, add organic matter if you want to have worms.

I like the fact you think out of the box,,,,,,,or bed as the case might be. I agree with previous comments but I'm not sure you got what you are looking for. To encourage and nurture worms it's a good idea to routinely bury kitchen scraps in bed or garden. Many do just that to amend soil while others put scraps in worm bins and some add scraps to compost. To get ideas of what to feed, search vermicompost. Any conversation about vermicomposting will include bedding ,that's organic matter suggested above. As for whether plants and/or soil benefit might vary dependent on conditions. Soil receiving doses of amendments every few days might not be the best thing for worms. In that situation a corner of bed might be left undisturbed except for additions of food. Beds worms find idea will be shrinking so be prepared to add organic matter ongoing.

talk with your local COUNTY conservation office.. and find local sources.. do not mail order in from china or god knows where ...

I USED TO TAKE A SOUP CAN AND GO WORM HUNTING during/AFTER RAIN.. AND JUST RELOCATE THEM INTO MY BEDS ...

OOPS.. lol

My father used to "seed" new lawns or gardens with night crawlers when I was a kid.

Have you got a compost bin? Compost makes a mulch that earthworms, etc. love.

I depend heavily on a worm population for tilling and fertilizing my garden, but worms have to have a food source to want to stick around.

Earthworms do not live everywhere. The worms require temperature and food.

If you havent seen worms in 4 years, maybe your area does not support worms…Elephants do not live in the artic, nor polar bears in the desert.

Are you trying to play ”bucket biologist”? Relocating non native species for your enjoyment?

Well, that's a pretty inane comment :-) Anyone should be able to figure out that you cannot compare worms to polar bears or elephants, both of which require rather specialized habitats. Worms will exist and thrive anywhere that has a temperate climate and sufficient moisture and organic matter to sustain them.

btw. most common species of worms found in our gardens are not native to the US or even North America. Most were imported either intentionally or inadvertently.

FWIW, We have worms on our property. We have a compost bin. The soil I’m asking about was brought in, worm free, and the new bed wall, in some places, is 4 foot high, filled with this imported soil mix.

At the risk of being repetitive, add organic matter to the beds of imported soil and they will come :-)

They'll get there. If you make the soil attractive to them, they'll find their way to that bed---despite the wall. If you doubt it, you can always take worms from other places in your yard and toss them in the walled garden. Worms reproduce pretty rapidly. I think the more worms the merrier, but I'd get local worms if I could.

If you move any,just make certain the whole family is relocated. There's been a lot of buzz on national news about kids being separated from their families in a strand land.

Gardengal's link shows worm eggs. Fun Fact: Once you know them, they're very easy to spot in your soil. They're shaped like little lemons and they range in color from yellow to brown.
