Question
This past Easter I received a beautiful luscious plum colored "mini mum" from my dearest friend, Laura Jane. At the time when she said, "I didn't give you cut flowers, because flowers die." I didn't realize how soon that would come to mean much more.

The Friday after Easter, Laura passed away and I have this living gift that's all I have left..... as silly as it MAY sound to some of you I will be beyond crushed and angry with myself if this plant dies....

The weather in Connecticut right now is insane.... In early April we had a 92 deg day but a few nights ago, a FROST!!!! WTF! In the sun and warmth, the mum was outside and I couldn't get home before the frost and it was also knock over in the brutal wind. Three stems snapped off and now the plant is in sort of a "C" shape. I've re potted it ever so gently in a bigger pot with
Shultz Potting Soil Plus and mixed in a little Shultz Peat Moss.
It's the most I could due with the money I have.  I could not plant them in the ground because I plan on moving soon.

There is a lot of adequate drainage, but though most of the leaves are holding up ( everyone is telling me how hearty Mums are) I'm so scared they'll die. At least half the flowers have bits of brown on the petals. I need to know what to do from here...!
I'll do anything....! HELP!!!!

Hi Amanda,
Thanx for your question.  Please accept my condolences on the passing of your dearest friend Laura Jane.  May she rest in God's eternal peace.  Desiring to keep a living memory of a departed loved-one is not silly at all.  I have some lotuses in my pond that my mother bought me for my birthday about 10 years or more years ago and I value them like no one else knows.  They are a living memory of my mother and how much she desired to make her children happy by sharing in their interests.

The mums you received are most likely "florist-grade" mums which means they are probably not hardy to Connecticut's Zones 5 and 6 USDA hardiness zones.  These plants are not grown by the floral industry to survive longer than a few weeks or months at best.  In the case of your plant, it sounds like it has had some difficulties and so there is some tip damage on the flowers.  All you can do is keep the plant well-watered but not soggy and feed it with a 12-12-12 house plant fertilizer following the directions on the package.  I would put the plant outdoors on a porch of patio where it will get 6-8 hours of sunlight, provided you are not anticipating any cold or frosty weather.  If so, bring the plant indoors of an evening.  If the plant survives to Autumn, once it starts to go dormant, keep the potted plant in a cool greenhouse where it doesn't freeze but it does get cool for the winter.  I honestly don't know if the plant will make it.  They usually don't.  I'm sorry.  I hope this helps.
