Blotting off all the bean plants after one of your Western Washington mists
, Eric. Terry cloth towels should work well. Those little packets of desiccant that are in medicine bottles - scatter those around the garden.
Okay, I suspect that it wouldn't be a good idea to crowd the plants. Air circulation is important. And, especially so for your part of the world.
I've noticed that you plant in beds, Eric. I often plant beans in beds and tend to crowd them, a little. One thing that helps keep the pods off the ground is to run baling twine ~ even for the bush beans. Keeping the twine taut allows the plants to lean
on the twine even if they aren't a vining variety.
I don't know about your California Blackeye. The Etna is a bush type, as I understand it. Commercial ag is usually "in charge" of crops like this. They have bred bush varieties for their own purposes. That doesn't mean that a bush Pinto, for example, is best for the home gardener. You may want to explore pole beans for your dry bean crops.
