I know it's not very clear. But this is a dahlia cutting in a 500ml (pint) plastic cup filled with soil. Although the cutting was pushed down the side of the cup (its stem was visible until the green algae formed), there is still no visible sign of any root development 32 days after planting. I know I didn't use rooting powder. But I'm sure it HAS rooted, because it's held firmly and is growing. Hope roots appear soon.POT TUBERS
I thought it would be good to see how the roots and tubers develop (should they ever appear), just as we did with the potato. Incidentally, it's worth growing a few cuttings like this and keeping them in pots (3.5 inch). They over-winter very well, once dried, and take up little space.
