Today I potted up the mystery seedlings, as they seemed to be getting rather large. 8 of the 16 seeds I sowed have sprouted, with those sown flat producing 5 seedlings, while those sown on their side produced 3.
I also potted up 22 impatiens seedlings.
It was cold working in the garden today, and the forecast for next week says we may have snow. I put some of the seedlings in this 'cold frame' type of thing (hope snails don't get in), and the rest went in the front porch.
This time last year it was mild and I had already planted the spuds. This year the cold seems reluctant to let go, and I'm still waiting to put the spuds into the ground.
