This is a useful article. I'm keen to have a go.
I have a question... Last year I bought two trailing begonia corms. They flowered last summer and died off around Autumn. I then stored them over winter and re-planted them in spring this year. Neither of them grew over this summer but one of them started to grow leaves about 3 weeks ago and it is growing quite well now. What should I do? Keep it planted or store it? The other corm shows no life.
