I have a sweet cherry cv. 'Lapins' on Gisella-6 dwarfing rootstock and a
sweet cherry cv. 'Rainer' on Zaiger. Northeast; New Jersey.
If left unpruned, what is the potential size (height/width) of these trees.
Unfortunately, they are two differing cultivars of two different
characteristics of vigor themselves, so that adds to the uncertainty
additionally.
I feel that, despite what is frequently advertised by some nurseries, they
will not just stop at 12' if unpruned; and that they will yet never get to
70' like a P. avium seedling on its own P. avium roots.
Thanks,
