I planted what I think is a Ponderosa lemon seed. The fruit was given to me so I can't say for sure what kind of lemon but it was BIG. That was in July 2015. It bloomed this January and is blooming again, June. It is about 5 feet tall and in a pot. I live in zone 7 with hot summers and fairly cold winters. There is one small fruit from January and tons of small ones now. Will the small ones ripen before I have to bring the tree undoors?
