Winter Sowing

This is my first attempt at winter sowing. I prepared three 2-liter
bottled (thank you, Polar Seltzer) and planted Hollyhocks in all
three. They are Fordhook Hollyhocks from Burpee that I picked up at a
store. I sowed about 20 seeds per bottle.
My 19 month old daughter helped by sprinkling the seeds in. But when I
asked her to help me carry them outside she literally threw one of the
bottles to me from accross the deck. I'm not expecting too much from
that one.
