Hi! One of nine "Red Intuition" has one fat root after being almost 3 months in the incubator. I am using George mander method. When it has more roots I will pot it up but what should I do next with this treasure? I don't know how tender this rose is. I live in Mount Pocono [z5-6]. All my HT came fine after winter. Should I plant it in the ground or better keep it in the pot and leave it overwinter in my shed? Please advise me.
