This is a journal of my vegetable gardens. Skippy was my first dog and he thought the garden was his, even though I did all the work. But Skippy always stood by me and was a great friend. Now Suzie and Charley follow in his footsteps and garden with me. We're located near Boston (USDA zone 6A). I have a community plot, a backyard vegetable garden, fruit trees and berry bushes, chickens and bees. I use sustainable organic methods and do my best to grow all of my family's vegetables myself.

pole bean problem

blighted pole beans blighted pole bean leaves
My pole beans have been suffering this year. The vines are very stunted and leaves are mottled and crinkled. I thought they weren't getting enough water and then I thought it was the black aphids that killed the nearby fava beans. But I think it is probably a mosaic virus (maybe bean common mosaic virus or cucumber mosaic virus?). These viruses are spread by aphids and the only solution seems to be planting resistant varieties. I noticed that most of the pole beans at our local community garden also looked heavily affected. It must be a bad year for this virus. The problem is affecting both varieties of pole beans that I planted in my garden back in May (Italian Pole Beans and Blue Lake) and the Scarlet Runner beans I recently bought and have in pots on my porch. Fortunately my bush beans (Royal Burgundy, Provider and Haricots Verts) and soybeans are fine so far.

Sorry about your beans! I'm growing pole beans for the first time and wondering when I'm supposed to see any beans; they have been flowering for over a week. Any thoughts?
thanks!

If you sprinkle ashes from your fireplace on the leaves,the plants will be disease and insect free.

Did you ever figure out what was wrong with your pole beans? My scarlet runners look just like this! i was thinking it was a potassium deficiency in the soil.

I didn't figure out more about this. I just grow virus resistant varieties in this plot since then and they do fine. My guess is still that it was a virus in this soil. Maybe bean mosaic virus.

Its shady and maybe the plants just don't have the strength to outgrow the virus here.
