Environmental stress - short of water, even though a while ago or only for a brief period.

That said, can you post a picture of the plant?

they are in a self watering containers, i have never let them run out of water. could it be a over nutrient problem? like npk or mag, cal. etc.or lack of something?

You said they are self watering? Are they in containers? I like your trellis. Please tell. what is the trellis made of???/
Thank you
jean

there self watering containers (earthbox) i made the trellis 3 of them and they fold flat for storage. they are 8 feet tall and fit over the container.

Terrybull, I am also growing a few beans in EarthBoxes this season and mine look very similar to yours. I just don't think beans planted in SWCs do very well in general. I know there are probably many exceptions and many folks will report fabulous results with beans in SWCs, but I suspect that moisture and nutrient levels might be too high overall. The high nutrient levels from adding the fertilizer strips when planting might actually inhibit the nitrogen-fixing bacteria growth that beans and other legumes need to thrive.

An alternative idea is that your beans growing in SWCs are simply overheated. Beans do not tolerate elevated temperatures well, and this is exacerbated by by being in containers with a (black) plastic mulch cover.

These are just theories. I have the same variety of beans this year planted both in the ground and in EarthBoxes. The ground beans look wonderful, but the EB beans look very much like yours.

Thats said, I love SWCs since they give me fabulous results with peppers, eggplant, okra and tomatoes! :-)

i use half the dosage of fert for beans. with my peas i use the white cover and they are doing great maybe i need to do the same. this is the first year having the problem.

I'm not familiar with the workings of your containers, but beans don't like wet feet and they don't like salt. Wet feet encourages root rot which cuts off the water supply from the roots. High salts prevent the beans from absorbing water from the ground, and beans are very sensitive to salt.

Depending on the fertilizer used and the makeup of your soil in the pots, you could be getting high salt levels in the ground if water isn't flushed through and out of the pot periodically. Additionally, if the pots keep the soil quite wet all the time, it could be too much which leads to root rot.

If it is salt, flush the soil a few times with water to wash the salt out. If it is root rot, improve soil aeration by reducing water or letting it dry out a bit, and hill the dirt up against the stems to allow the beans the best chance to regenerate roots.
