Growing reed tubes

Out of curiousity, is there a plant/bush/tree that I can grow in my area (Oregon Willamette Valley) that will produce acceptable tubes for solitary bees.

I had originally planned to use drinking straws, as they are easy to get ahold of.
But I would prefer to grow something myself, if that is a reasonable approach.

Alternatively I suppose, would paper drinking straws work?

Any ideas?

I just made 100 or so of them out of old dry blackberry vines. Good for pith bees all left alone and when hollowed out good for others. The thorns help keep mice off.

Of course bamboo works. Reeds and other thick stem grasses.

teasel (Dipsacus species). may be considered a noxious weed in your location, but maybe not. grows wild all over the best coast.

Blackberry canes... beautiful, I had not thought of those. Both plain and hollowed out, great idea.

We grow wild blackberries around here everyplace, so I do not need to grow them, I can grab some.

Thank you

Just make sure to get the old dry ones they don't like fresh ones hollowed out.

Hmm.... I had thought about cutting them green, trimming them to the length I need and then letting them dry until spring.
Then I can hollow them out before I put them out in spring.

It seems like that would making it easier to trim them to length.
Would that work?

Dave Miller posted some great photos of mason bee shelters he made in this thread.

One of the mistakes beginning mason bee keepers make is that they forget (or don't know) to harvest bees in the fall. If you let bees survive on their own, mite infestation occurs and you begin to lose more bees than you started with.

That's why bamboo isn't a great nesting reed. It's too strong and can't be opened without killing the bees.

Reeds, on the other hand are awesome... unless you leave the bees on their own.

Why manage bees? It's the same thing as managing cows or sheep. If you don't care for them, pests/disease overrun.

You could try Japanese Knotweed. It's invasive and spreads fast, but you'll get a lot of tubes really fast. I have a small patch (50 square feet) that I harvest once in the spring for food, then cut a few times a summer for a compst additive and then a final cut in the fall to dry and use for next years mason bees. Each successive cutting produces narrower diameter stalks. The early summer ones are about an inch while the fall ones are closer to a quarter inch or so. Once dry I store them in the basement till after the wet spring then just pile them up in a dry area.

Here's another idea for "reeds"... the dried stems from Jerusalem Aritchokes.
I had a bundle of them on the porch for a fall/halloween decoration.
After cutting them to size, and cleaning them out with a wire they look just perfect.

I have seen mentioned Raspberry canes as well.
