Its bad info to tell someone a seed plant will only live a year.
Consider this.
Some plants in South East Asia, will live for several years, in the wild. Think of the stress of vegging, flowering, vegging flowering a few times does, and they still live, with no human intervention. And they are seed plants.
For long term health of a plant, one must keep them under good light. Soil must be spot on. Good air exchange. Give them sunlight, when possible. Prune roots at certain intervals. Keep them as stress free, as possible.
One has to stay on top of the plants, to keep them healthy, long term. Most just dont have the experience, resort to unsubstantiated, experimentation, listen to bullshit on the internet, from unreliable sources., and end up with dead plants.
Its not rocket science to keep plants alive for decades, but one must abide by certain guidelines, to keep them healthy. Any deviation from optimal, and they will suffer.
Id also add, the person that gave smotts the advice, probably meant an outside plant has a viable life of a year. Which is 95% TRUE, WITH A FEW EXCEPTIONS.
Probably 99% of all plants will die outside, with in year, or less, if left to nature.
BUT, one could also dig this plant up, if its outside, put it under a light, and keep it alive, for decades, if it will reveg.
