houseplant lifespan question
Okay, so I read the life span of a pothos is 10 years or so. Weather this is accurate or not I don't really care. My question is this: I keep taking cutting off of it. Does that start the life span thing over? Like for example if I get a baby pothos and grow it for 5 years, then take a cutting, should I expect the cutting to live for 5 more years, or 10?
I'm interested in how this applies to all plants, not just pothos. (In case the answer is different for different ones..)
