One best pear I should grow

Not sure you read this thread on quince and cold hardiness.

Quince rootstock

I have no idea what type of Quince my Potomac pear is grafted onto, but it has survived -13 and -11 in consecutive years. Like AJ says though I have noted some very mild chlorosis and it is certainly not a product of any nutrient deficiency. It could well be that of the cultivar, but never read anything about it before. It certainly doesn’t grow as strong as seedling, that’s for sure.
