ussurian pear ready to transplant

ussurian pear ready to transplant. the large pear seeds take off and grow quickly, I started some in community pots just to save on greenhouse space. pear is tricky to grow under lights or with close spacing, there's foliar disease that will turn the leaves black and defoliate if there isn't enough airflow, apples will get scab, pears get this. thinking I'll pot up and move them outside, even though we had ice on the pond this morning, a bit of frost should be fine, cold nights will slow them down but since they were started outside I think there's enough cold resistance
