I made a big mistake with the pole beans. As soon as they came up from seed, they looked diseased. And, as it turns out, they are not pole beans at all, but a bush variety of Red Noodle. I must pull them up and plants snow peas for the fall. Not shown in this picture, is a big wine barrel filled with lettuce, chard, sorrel (red veined) that has struggled a bit with leaf miners and heat, but by and large look and taste great. Those are keepers for a year round deck garden.
Our deck is a brutal place. Even though our house is painted dark green, there is a lot of reflected light and heat. And wind. So the plants dry out quickly and have to be watered more frequently than if they were in the garden. The area of the deck I chose is somewhat protected from the wind but also gets less light, and I think that is what stymied the squash.
It was a good idea, though, and makes the deck a more livable and attractive place. It's fun to go out and grab a cucumber for the supper salad.
