I live in Phoenix, AZ and I am attempting to grow some pole green beans for the first time. Because of the heat, I water them almost everyday, but they don't seem to be getting any taller and the leaves are a pale yellow-green. I planted them with the south sun exposure next to a brick fence and built a 'teepee. I am wondering if green beans just do not grow in Phoenix and I am wasting my time. Any advice would be most welcome. Catherine.

You sure you need to water everyday ? With yellow leaves you could be drounding them.
They will grow slow if nite temps are to cool.
What type of soil you have, your temps, when you planted them, and a picture would be really helpfull.

Also, have you amended the soil with anything, or given them any fertilizer? Beans are pretty heavy feeders since they grow fast.

Yes, please do post some pictures so we can see what's going on.

Depends on what kind of beans. I'm trying peas, and they got badly sunburned in a northwest exposure. Had to put them under shade cloth. When packets say full sun, they aren't talking full Phoenix sun, that's for sure!

It sounds like you don't have enough nitrogen in your soil. Have you given them a well balanced plant food?
