Snow Peas
I live in Phoenix, Arizona. I have snow pea vines which are about 2 1/2 - 3 feet tall. They seem really healthy, but the problem is that the bottom portion of the vines seem to be turning yellow and drying out. I have some carrots, radishes, lettuce, and zinnias in my garden. Everything else is good. I water regularly and put garden soil in the area when first planting. I use Miracle Grow as well. The garden is shaded by a large Jacaranda tree, so it doesn't get direct sun.
