Outdoor hydrangea cuttings rooted sep 2011

Below are photos taken feb 10 of my outdoor hydrangea cuttings rooted in September of 2011. I covered them using the pots they were rooted in and I placed the rocks to keep the wind from blowing the pots away. The first cuttings shows two very plump buds. I hope for not late frosts this spring. I will keep these covered well into April.
