Help please with trailing petunia

Hi,  I have had this dekko light blue petunia (trailing) in a small pot on my fence. Can anyone advise me if it is worth putting this in a bigger pot and putting it in my green house over autumn or winter? Any advice is much appreciated.

    I think petunias are annuals.  So, no.  But give it a try and let us know.

    If you want to save money, grow from seed, petunias are very easy.

    I would cut it back by about a half and give it a go, I have managed to get  a trailing petunia to regrow this way but flowering was poor. Fresh compost and a slightly bigger pot is worth a go be aware of compost gnats.

    If you get some fresh new growth on it you could take cuttings. Petunias are tender perennials but are usually grown as annuals because of needing space and warmth to overwinter, and because they get straggly and young plants tend to look better.

    I left some petunias out in a hanging basket last winter, zero care - they survived and flowered again this year!

    Thank you all for responding. I will give it a go and see what happens.

    Do let us know how you get on. With climate change many things may be possible that used not to be. 😊

    I agree with @Dovefromabove I think advice will be changing regarding plants like Petunias, Pelargoniums, Nemisia and many more. Lots of gardeners especially in the south are overwintering these plants.

    It depends where you live. I have left petunia in hanging baskets in my greenhouse over winter and they have come back late spring. However because the root ball in the hanging baskets is so tightly packed I just let it grow on enough to the point where I can take cuttings, from those cuttings I take further cuttings. 

    I would give it a go as others have said. I would put it in the greenhouse now, trim it back a bit and feed it and it should put on a bit of new growth until mid October then just leave it be just keeping the soil damp rather than wet until late spring then water and feed when you see new growth.

    If it survives, next year save some seed then you have two shots at regeneration.

    The name is trademarked.  It is unlikely to come true from seed.
