Pole beans struggling, any ideas?

Sorry I can't be of much help as to what is going on with your beans. I put my seeds in about 8 weeks ago and mine
are much further along. I find pole beans just don't produce a lot for me. I've done 3 pickings so far off about 20 ft. of trellis and only had enough beans for one serving of steamed green beans for 3 people.

My usual climber bean for the past 20 years has been the Japanese Yard Long AKA Asparagus Bean and they are very plentiful and much faster growing than the typical Kentucky Wonder pole bean.

I'm actually thinking of pulling my pole bean plants and going back with the Yard Longs for a much better harvest.


Edited for this:

There are several reasons for what's going on with your plants. Both overwatering or underwatering can cause the yellowing to occur. If you underwater it doesn't allow the plants to pick up nutrients. If you overwater it suffocates the plants roots, again not allowing for nutrient uptake.

Soil not in the right PH range of 6-7, poor soil drainage, insufficient hours of sunlight, etc.

So many variables.
