I have found that clean grow rooms with new moms made every 90 days or so can produce viable clones for about 3-5 years. I have clones from clones that are now 12 years old and still going strong. This will create a flame war from those who choose seeds more frequently but If the plants are clean, well fed and free of pathogens they can go on quite awhile. I have noticed those who say 1-2 years max don't have clean grow rooms.
There are varieties of heirloom seedless grapes cloned for thousands of years in Iran. There are seedless citrus in asia that are in the hundreds of years by clone. There are rose varieties four hundred years old.
I think it's about being clean. Diseases will introduce deficiencies however. I think for the average grower, 3 or so years before problems arise. I will say my ten year old cut is still very vigorous.
