Which rootstock are you trying Sierra on? I see your tree in your California garden.. Did some Google reading and Dave Wilson Nursery must have selected a wild Prunus subcordata because the name Sierra falls onto the list of common names for P.subcordata. Regardless, great!
I’m only curious if the rootstock you’re trialing Sierra on will accept nectarine and peach… obviously you’re several steps ahead of the game, than me.
What rootstocks would you like to have for the peach and nectarine? Again, I’m curious.
Which pear rootstock are you trialing?
