How do I over-winter my rose seedlings??
I have about 30 or so roses I have started from seed that sprouted in the fridge in May. They range from between 3 inches high to 6 inches. Would it be safe to plant them in the ground here where it can go down to -40 (the parents do survive)? Should I keep them in the basement under lights? Or should I try to force them into dormancy in pots and put them in the pantry that stays at about 7-10Celsius/44-50Farenheit.
Thanks. Here's a link to some of the blooms.
