Plants encounter problem

I don't know what's wrong with my plants, but it seems like it's dying. Yesterday morning, while I watered my plants, I saw my veg whithered.

It's not only happening to my french bean but my mini rose too. How sad..........I wondered is it I over-watered the plants. I really don't know, but I've decided to take down the veg before all died.

Meanwhile, test & trial to see how I can resurrect my plants.....................
