End of season reduced Cannas
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?
