Thank you all for these suggestions. Mostly what folks in this neighborhood have is pine straw which I didn't think would be to the worms liking. But if they eat the microbes off the organic stuff, I do have sticks and certainly plenty of weeds. The worms didn't come up from the ground; they were in the; rabbit manure I was given. I did put on the top of the soil the snow pea plants I mentioned. The worms are already in the soil from the rabbit manure, I'm just trying to keep them there. We, unfortunately don't eat much vegetables that would have left overs, but I'll add that to the bed. What about orange peels? We do have coffee grounds that I can add as well.
You often hear people that keep worm bins warn to NOT put orange peels in the bin. However, most worm bins are relatively small and and the citric acid could hurt the worms.
However, in your case I would add the orange peels, because they have room (unlike most worm bins) to stay away from the orange peels, until they start getting moldy. Once the orange peels get moldy the worms will eat them as well. I always mix in orange peels to my little compost piles with no problem.
BTW, your question about orange peels reminded me of a story from Costa Rica. It's very interesting about two scientists that had 12,000 tons of wastes from a company that made orange juice.
Very Interesting. I posted only an excerpt, but it's a good article to read.
Princeton researchers explore how discarded orange peels revived a Costa Rican forest.

Orange is the new green: How orange peels revived a Costa Rican forest
In the mid-1990s, 1,000 truckloads of orange peels and orange pulp were purposefully unloaded onto a barren pasture in a Costa Rican national park. Today, that area is covered in lush, vine-laden forest.
A team led by Princeton University researchers surveyed the land 16 years after the orange peels were deposited. They found a 176 percent increase in aboveground biomass — or the wood in the trees — within the 3-hectare area studied (7 acres). Their results are published in the journal Restoration Ecology.
This story, which involves a contentious lawsuit, showcases the unique power of agricultural waste to not only regenerate a forest but also to sequester a significant amount of carbon at no cost.
“This is one of the only instances I’ve ever heard of where you can have cost-negative carbon sequestration,” said Timothy Treuer, co-lead author of the study and a graduate student in Princeton’s
Department of Ecology and Evolutionary Biology. “It’s not just a win-win between the company and the local park — it’s a win for everyone.”
