Should I prune my new bush bean plants?

[jayb0g]

I bought three small bush bean plants. All of the available plants had leaves that were drying up, but I picked plants with healthy looking new leaves. Should I remove the old leaves?

No. As long as they have a good green color they are providing some photosynthesis. They will soon die and fall off. It looks like the seller forgot to water them
