Just found a couple packs of pole beans leftover from last year. Turning over a few ideas in my head what to do with them.
A few years ago, I tried growing some pole beans alongside my chicken run fencing. I just dug/tilled a small furrow alongside the fencing and planted my beans. They did OK, but nothing great. Mainly got crowded out by lawn grass creeping into the beans. I think a big part of my problem is that my native lakeside soil is just too sandy for good plant growth.
Last year I did not even plant any pole beans.
I am stuck inside today because it's raining outside. I got my first idea on this potential project from a question I put into the Google search and got this result...

Since I found a couple of unopened packs of pole bean seeds today, I'm thinking maybe I could build 16-inch high, 4-foot long, 6-inch narrow raised beds alongside my chicken run fencing. I would fill the bottom half of the pole bean raised beds with hügelkultur wood and top it off with my mix to topsoil and chicken run compost mixed 1:1.
I am thinking that 16 inches off the ground - on the outside of the chicken run - would be high enough that the chickens would not reach into the raised beds and pluck out the seedlings as they start to grow. Starting off with quality topsoil and compost in the raised bed should be much better than my native lakeside sandy soil in the ground. Also, I would not have much of a problem with lawn grass and weeds creeping into the pole bean raised beds. I think I might have better success with the narrow raised beds idea.
Found a google picture of something close to my idea. Just imagine some 4-foot-long narrow raised pole bean raised beds alongside the chicken run fencing...

Of course, I am saying 4-foot-long because that makes it easy for me to use the pallet wood 2X4's. Each raised bed section could be placed end to end for 8, 12, or 16 feet in total length. I would still use the basic design of my 4X4 foot 16-inch-high pallet wood raised bed v2.0. It would just be only 6-inches wide.
And, if the pole bean raised beds alongside the chicken run fencings does not work out, I could easily take it apart and convert it back to my standard 4X4 foot raised bed design.

Well, I am not fixed on the notion of only a 6-inch-wide raised bed alongside the fencing. I could go 1-foot-wide or even 2-foot-wide, planting beans along the fence side but planting other non-vining crops in the rest of the raised bed.

If anyone has used their chicken run fencing as a trellis, please let me know what worked for you, or not. Thanks for any suggestions and/or feedback.
