I have a beautiful mum plant in my dining room. It's full of bright
yellow, daisy like flowers. It is not the hardy variety and I live in
Boston - cold! I've had it for about a month and the flowers are
starting to fade.

When the flowers go do I have to throw it out or can I do something to
save it until next year?

Thanks

My father in law was able to grow Mum¹s at Lakehurst NJ. USA. SANDY
SOIL. I treat them like annuals. Some are forced to bloom and I guess
that diminishes vitality. Around here we can go cheap and dig our own
local plants.

Here is a site that touches on your question.
