This is one of the north windows, and these are dahlia bulbs in moist growing medium. I took the sprouts and potted them up, placing a glass jar over them to prevent their drying out. Within three weeks they had rooted. I then took the rhizomes and planted them in the garden, and within another three weeks of planting they had sprouted. Now one of the sprouts from the rhizomes is three inches tall, and about four inches in diameter.
I still have to plant the dahlias in the pots -- haven't prepared the flower bed yet.
These are small, single-petal dahlias -- they'll grow up to 40 cm tall. But you can use the same technique to increase your stock of the larger hybrids.
