Cosmos germinated in three days. I think I'm cheerful about it.😏 it seems a bit eager though.
Mine too (Xanthos and Peppermint Rock). I thought I'd left it late enough but maybe not. I'm not really bothered if the Peppermint Rock ones end up leggy and no good because they were a reduced packet from B&Q clearance last autumn, but the Xanthos weren't cheap.
If they're too leggy , they're happy to be cut just above a pair of leaves and they'll bush out from there
They'll be pricked out and planted up to their necks when they're big enough, and pinched out later if they don't look like branching on their own . Don't want spindly plants with a single flower on top of each, which happened last time I tried cosmos (many years ago, I didn't know to pinch them out).
At the moment they're only just unfolding the seed leaves, but it's only
4 days since sowing, which is quicker than I expected. And they're not
even in the propagator, just on the windowsill in an unheated
east-facing room.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
Having spent the long weekend cooking, eating and entertaining family, I didn’t think I’d get the green waste bins filled. However, it was such a lovely day, I managed to pull out a load of gaultheria, lopped some laurel overhanging from next door, and topped it off with a pile of birch twigs from the lawn. Feeling very virtuous!
