What is the best care routine for a yellow potted chrysanthemum plant?

My plant's flowers and buds are turning brown but the leaves look fine and healthy. Any suggestions would be very welcome. I live in London.

What is the best care routine for a yellow potted chrysanthemum plant?
The best thing you can do for a potted chrysanthemum is to put it in the ground. I go to the grocery store floral departments and buy chrysanthemums that are bloomed out and then plant them in my garden. They bloom each spring and each autumn. They are in bloom right now and are beautiful.
Reply:Well, you know, plants go thru a rejuvenation process. Can't have blooms and buds all the time. At some point, the plant stops this and just grows the greenery. This usually happens in winter for most plants but mums are cold weather guys so they hold out a bit longer...but still, they stop their budding at some point. Sorry I'm not more scientific but I'm just speaking from experience.
Reply:unfortunately these store bought greenhouse plants are not meant to last that long. you might try cutting off all the buds and placing it in a cool bright location. however, the best chance of saving the plant would be to plant it outside. they need lots of sun to stay compact and vigorous and only bloom during shorter daylengths (usually fall). greenhouse producers use artificial light cycles to bring the plants into bloom for sale as temporary house plants. they really dont thrive indoors except as a short term prospect. put it out, water it well and next fall it should reward you again.
