Dahlia cuttings
Last year I didn't lift the tubers, but layered the beds with 150mm of
straw, with some dung on top. I therefore missed the opportunity to
reproduce from tuber splitting.
Mid August I took 12 cuttings (fuchia style using rooting powder), of which
7 have taken. This is the first time I've tried this, so some advice would
be appreciated. What's the best chance of these plants (now 120mm tall) of
Winter survival?
1. Leave them in an unheated greenhouse (min Winter temp 1C)
2. Unheated porch (min temp 6C)
3. Indoors on windowsill, but near a radiator (it's the only indoor place
available).
TIA
