I have several of these dotted around garden never had problems over 9 years. Now just two at the front have got leaves turning brown and plant looking very unhealthy.
Unfortunately, your photos did not come through. I am unable to see the damage. In the meantime, these articles will provide reasons why this could be happening:

Hi, I am based in Cambridge, UK. I purchased some bedding chrysanthemum plants from a garden centre and planted them in my garden in mid-July. Since planting, I have seen the plants produce new buds which then turned brown and did not open. This was accompanied by leaves developing dark/black patches. Following heavy rainfall in mid-August, the plants produced a lot of new growth and new buds. However, I noticed that the leaves around some of these buds are curling upwards and am concerned that the buds themselves could again fail to open. I have attached pictures showing a bud that turned brown and did not open, the dark patches on a leaf and the leaves curling around the new buds. Apologies in advance - there are bits of mown grass on some of the leaves, but I hope the images are sufficiently clear. Would you be able to identify the problems and what could be done to remedy them? Many thanks in advance. Best wishes, James Ng
This article should help. I would cut off as much of the dark buds, leaves as possible.
Ok I have recently planted mums in my flower bed. And would like to know instead of using leaves, or mulch to winterize can I use a good layer of pine needles?
In cold locations like Fort Blackmore, shallow rooted mums can be mulched in the fall using about 3-4" of leaves, wood chips, pine needles, evergreen boughs or straw around the base of the mums.
I just bought three new mum plants. They were not opened up when bought them. How long will it take for them to open up. The sunny part of my balcony has only sun for 3 - 4 hours. Can they take some shade?
The more sun they receive, the faster the flower buds will open. I have mine planted in full sun conditions (more than 6 hours of direct sun) but the least amount of sun is probably around 4 hours or thereabouts). If brought indoors, place the pot in a southern facing window to maximize the amount of available sun.
In future years: tall and thin mum stems cannot support the heavy blooms in the fall. As a result, the plant may generate less blooms, if any at all (if it gets a lot of shade) and the blooms may appear smaller than normal.
i am keeping them in a dark cold porch the started shooting within three weeks they now seem to be wilting a bit i have tested the soil and its damp can you help
Unfortunately, it sounds like the soil has thawed out from freezing too early! If this is the case, you may want to put them into a higher lighting situation, such as indoors under grow lights.
Here are some articles that will help:

I'm slowly learning about plants and where to place them in my apartment or on my balcony as well as learning how much and how often to water them. Can chrysanthemums grow in shade and sun? How much sun can they take? The place I am thinking is that they would get full direct sunlight between say 1pm and 5pm. In the morning shade with lots of light. How much and how often must I water? To be honest, I don't know what to do with them once they have finished flowering. I normally land up throwing them away because that's when the plant dies. So I find them a waste. I would prefer for them to be outside. Thanking you kindly. I look forward to hearing back from you. Kind regards Barbara Hoon South Africa, CPT
Garden chrysanthemums are hardy to -32 degrees C. so should work fine in a container on your balcony. They like full sun and water when the soil dries. Pinch them back from April to June to keep them tidy and not so tall.

Can anyone tell me what type of plan this is? I am guessing it needs less sunlight or something more. Please help before kill this poor plant for the love of God.
It is very hard to say what it is in that state. My guess could be Chrysanthemum.
