Well, it's growing...
Above, the watermelon's flowers, below, the cucumber.
Frank's suggestion of a horizontal trellis of sorts (it has to be very cheap, and must not blow away) will be applied this weekend, for the watermelon, which is running away. I don't see the vines or fruits (please-may-it-make-fruit) being very happy on the blistering tartop. And maybe for the alleged bush cucumbers, too.
If the cucumbers make fruit I will turn them into pickles. We had delicious pickles at Buttermilk Channel last night, which, aside from my cheese at the end of dinner, and a very good lady maitre d', were the best part of the meal. A very meh meal.
These are my grown-from-seed Mexican heirlooms, which came up on the terrace earlier in the year. They seem very happy. To my horror, I snapped the central stem off one while trying to poke it back into its cage. Loss, and shame.
I want more.
