So I grow flowers for cutting and from early spring to November I'm getting a good supply. I'm wondering how I can fill the gap over-winter. Does anyone have experience of forcing daffodil/hyacinth bulbs for example or any other ideas for a frost free greenhouse - maybe perennial carnations? I keep my greenhouse at 5C minimum. One thought I had was to bring dahlias in before the first frost and try and keep them flowering until Dec/Jan.
