Our Fordhooks have been blooming for well over a month, and the plants are still covered with blooms. We have pods in the 2 1/2 to 3" range, but the beans themselves don't seem to be filling out very well. Is it common for them to mature this slowly?

We planted one row about 3 years ago with dismal results, with the exception of the plants on either end of the row which were able to support themselves on the fence. The unsupported plants in the middle of the row all fell over when they reached about 12" in height. This year we supported each plant from a horizontal wire at about 42". This worked very well as most plants are approaching 3 1/2' in height. We are not having any trouble setting fruit, just curious why the pods are so slow to fill out. Any thoughts or information will be greatly appreciated.
