The garden is giving up its ghost. It's been too stinkin' dry and too bloody hot for too dang long. The cucumbers are turning yellow. The tomato leaves are curling. The green bean plants are being devoured by grasshoppers who think the shade of the cucumber and squash leaves are a safe haven, except they're wrong because the squash and cucumber leaves are being devoured by the squash beetles. The herbs are drying where they sit. The watermelon plants are the only things still truly alive, and even that's subject to some debate.
In other words, the war is over. The heat has won. The brown flag of botanical surrender is waving.
