I see at my B&Q at the moment that a lot of plants are on sale as they die off for the winter. I bought a few Hostas at half price yesterday which I will plant out next spring. But I was wondering about Cannas (which I know nothing about). I'd love to put some in next year. Is it a good idea to buy up some half price plants now, stick them in the greenhouse and plant out in spring, or is it better to buy the corms next year?
Definitely buy now. You will get them started earlier, and the corms will probably be bigger.
I understand that they should be treated as dahlias over the winter, so I'd wrap the pots especially if you dont heat the gteenhouse over winter.
I noticed that our local GC selling off loads of stuff this week. Often a good time to get bargain herbaceous & other plants & it's still fine to do an autumn planting of lots of things- not your cannas though. J.
Every autumn I dig up the cannas and put them in pots in the shed and every spring I have a pot of soil and no tuber, what am I doing wrong?
often you can get good plants in sales,with Cannas you need to keep them frost free until late spring when frosts are gone.
I am now confused christopher2 do you just wrap the tubers, not in soil?
flowering rose are yours in pots of compost?
Christopher2 if you say it is ok to leave them in the soil I will try that, I would love a big colony of them.
