Green beans dying
The Blue Lake Green Beans in Harold's garden are dying. The beans sprout okay but now the stems are splitting then the leaves turn brown and the plants die.
Alcona County Michigan
Inspect the bean stalks closely to see if you see any evidence of insect damage. If an insect is not the culprit, then possibly the issue could be related to a nutrient deficiency in the soil. If a soil test has not been done in the last several years, I would recommend you do so now to determine the available nutrients. You can purchase an MSU soil test online from the bookstore at the link below. The kit has everything you need to send soil samples to the MSU lab and results will be emailed to you within a couple of weeks.
From your description, this doesn't sound like a disease issue but just in case, I am including a link below with more details and symptoms of bean diseases.
If replanting you may also want to try some new seeds or a different variety which would eliminate the possibility of an issue with the seed.
Hope that helps.
