Q. I recently planted bean seeds in pots on my porch here in Las Vegas. However, after the bean stalks were half a foot tall, they bent over, turned dark and died.
A. This is probably crown rot. If you plant beans when the soil is too cold they have a huge chance of developing crown rot at the point where the bean stem enters the soil. This causes the stem rot, the plant dies or we say “collapses”. If you plant them when the soil is warmer, they have less chance of this happening.
