Question: I bought a 4-in-1 mild climate apple (Anna, Red Fuji, Gordon, Golden Dorsett) but there is no rootstock info on tag.  Can you tell what rootstock it is on?
Thanks,
Paul

Answer: Paul,

The 4-1N-1 Apples are grown on EMLA106 virus certified, semi-dwarfing apple rootstock.  This rootstock produces a tree about half to two-thirds the size of a standard apple tree. It does not sucker and the rootstock is resistant to wooly aphid.  EMLA 106 has been planted intensively in the East and West and is an excellent producer.  We chose this rootstock knowing that most of these 4-N-1 trees will be planted in homeowner yards where space is at a premium.   It should be planted on well drained soil as it is susceptible to crown rot.

Enjoy your apples!
