Yes you heard the right thing dear. Dishwater is really helpful for your leaves. You should use dishwater twice in a day.

MomesqNY, I am having the same problem. I just tore down all my pole beans today and have to replant. This has been going on for a month now. I had perfectly healthy plants and started noticing that entire poles were missing leaves (whole leaves chomped off). Sometimes just the top leaves and then the bottom leaves would be gone the next day or vice versa. The beans were left completely untouched and intact. I am certain it is an animal and think it may be a rat! I've seen a rat running along the fence on that side of the yard several times. I purchased a rat trap 2 weeks ago, but have yet to set it up. I think that is the only critter that is capable of climbing the poles without dragging the whole plant down. We also have squirrels, but I haven't seen them in that area during the daytime. It is definitely a nighttime creature! I checked for droppings but didn't see anything, but I am not ruling it out. Does this sound like it may be what's eating your leaves as well? I'd hate to admit that there are rats on my property, but I am at a loss as to what it could be. We also have skunks, raccoons, coyotes and opossums but they would be much too big to climb the bamboo tepees I set up!

It might be deer. I have had deer eat all the leaves off my pole beans on the side facing the fence. Not to worry, if they haven't eaten the vines the leaves grow back and flowering continues with beans galore.

Possibly cutworms, I had this happen to me one year, one pole, 8 plants, almost to the top of the pole. All vines had been neatly cut off right where they emerged from the ground, it was cutworms in my case. Sorry I don't have a recommendation for you, most insecticides have been banned here in B.C. Maybe someone else will chime in with a solution. If planted around a pole maybe give the seedlings a collar, toilet paper tubes might work. Annette
