Is it necessary to buy a green house for my flowers?

I plant some flowers in several flowerpots, because it is very cold in winter, so I place them in house, but I found that all of them don't live good enough. So I am thinking whether I should buy a green house and put them in it. I found this one on a website. But I don't know if it has good effect on those flowers. I hope that you can give me some advice. Thank you very very much.

 

Hiya Jane.

It would help if you could tell us which flowers you are talking about?

Cheers...Freddy.

 

Are those geraniums I see in the picture? The less hardy kind so often used as bedding plants?

If I'm right, and I should throw in a disclaimer that I don't normally grow them, they need a bit of special treatment to get through a British winter.

I think you're supposed to dig up the roots, store them in newspaper in a cool dark place (but protected from the frost, like a shelf in a shed or out house), then replant them in spring.

My mam's late uncle Alf, who was very green fingered, once told me he couldn't be bothered with that kind of effort, so he used to cut the top growth off, stop watering the plant so that the compost dried, and then stored the whole pot in the shed. Then in spring he'd just get them back out and water them, and they'd grow back.

 

I hope you did find that pic on a website, As those flowers will not last through the winter, Nothing to do with the frost, but the fact that at some point between Nov and Feb the pots will be lying shattered on the ground, and the clear poly tent blown away

The recent cold winters have taken their toll, but as I grow a lot in pots too I have shifted my attention to tender bulbs and tubers. The advantage of these are that towards the end of the season you withdraw water, allow the soil to dry out and store the pots in the garage, the stair cupboard, the loft etc.
