What happens to phloem tissue production over several years?

Does it continue to grow or does it die out? Thanks for your time and help.

Unlike the xylem which accumulates and forms the wood of the tree, the phloem is part of the bark. The bark will wear away as the tree get older so there is not the accumulation as with the xylem. The cambium will continue to produce new phloem as the xylem is produced. This will keep the integrity of the bark

the phloem tissue will be of no function that will result to the annual rings of the tree

the vascular cambium continues to produce secondary phloem until the tree dies.
