I have some chrysanthemums (pot mums) outside . will they survive winter?

bought them when small, they flowered in spring in small pots, i replanted them in the borders and they have grown into small bushes with lots of flowers which are just opening. will they survive the winter .? i dont have a greenhouse but would one of the metal-frame ones with the plastic roll-down sheeting be ok? thank you.

They don't like frost but some varieties are hardier than others . I have had some survive last winter outside ( they wouldn't all fit in the greenhouse) because it was mild but generally they should over winter in a green house. Failing that you can buy a fleece type of material fron garden centres that can cover them and protect them from the frost - put them under a garden bench or table so they don't look too unsightly. A small cold frame type shelter you describe might be suitable but cover them with the fleece as well. Don't over water them either , just keep them from drying out - take loads of cuttings in the spring and you won't have to buy any more either. .

Reply:The plants should survive the winter provided we don't have too may many hard frosts. If up north you could have a problem but I live in the South West and my plants survive every year. If in doubt cut them back once they have flowered and cover them with straw. I have one of these metal framed greenhouses and they kill off the plants because the plastic holds all the moisture inside and with geraniums they get leaf rot. Personally I wouldn't bother buying one.
Reply:There are lots of different types of mums -- some are hardy outside all year and some will survive only in warmer climates ie. zones 7 or warmer. Do you know what climate zone you are in? Google "climate zones" or "temperature zones" and you'll find a map that will show your zone. If you're in a spot that gets consistent temps 20 degrees or lower in the winter months it helps to mulch the plants with a couple inches of hay, leaves, or even pine needles. Snow cover is a big plus for insulating perennial root systems. Again, Google "mums" and you'll likely find lots of info. Good luck!
