I've experimented with propagating the Snowdrops that have colonised the back of the garden [see Mondays entry]. The simplest -and probably the most effective way- to multiply Snowdrops is to lift a clump after flowering and plant it straight into the ground elsewhere.
Thus I have extended the existing patch with transplanted clumps which are clumping up nicely in other parts of the garden. Traditionally Snowdrops were sold 'in the green' in late winter/early spring rather than being sold in autumn- the bulbs don't respond well to drying out. Purchasing Snowdrops in autumn is probably best avoided unless you can be sure the bulbs are freshly lifted.
I also wanted to see if I could grow them on in pots as well. I tried lifting clumps in the green and separating the bulbs. The root disturbance seems to set them back, growth is limited and they're shy to flower. On the other hand planting a clump straight into a pot with some John Innes works much better as seen above. These were lifted and potted about ten months ago.
