Question
How can you tell when they are ripe / when they should be picked?

Answer
Hi Dave, when they are fully plumped out, this can take months to happen, but you will notice over that period that each finger begins to swell, when they have swelled to the point where you have several weeks go by and there is no further plumping out then it is time to sever the bunch from the plant and hang it inverted in a cool dark area, always sever them before they begin to turn yellow....Nick
