Can you take cuttings from mature Dahlia (with no new growth from tuber)?
I have a dahlia which a friend has admired and asked for a cutting. Since it looks nothing like the plant I ordered from Sarah Raven, I can’t tell her what to buy. Last year I tried to take cuttings from new shoots off a dahlias main stem. With and without rooting powder, was careful not to try to plant hollow stems... Still, no joy. Is it even possible? TIA 😬
