| A good indicator of collar rot is when the plant shows less vigor than it should or less vigor than its neighbors |
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.

| Once the plant is lifted from the soil you can inspect the stem at the soil level. Where the brown part of the stem and the green part starts was the soil level. This is also the place where the bean stem was attacked by collar rot fungi. Avoid planting in soils that are too cold. |
