Is Liberty a ‘tip-bearer’ ... and how many buds did you leave on the scion, and have they all bloomed? Usually at the base of a vegetative bud there are two latent buds
that will activate if the primary bud is damaged. …I’ll assume on an apple, the same is true with a blossom or fruit bud..?
I’ve had scions simply bloom, and believe they were tip bearers. But, I’d placed them as bark grafts under the canopy of a well established apple tree where they got so little light … they lived, but did nothing more than remain ‘fruit spurs,’ with no vegetative growth. If you’ve more than one bud, ‘they’ should take off.
Fruit buds or spurs are easy to spot, they’re fat, and on older wood. They’re a real problem at the Propagation Fair
… as ‘that’ will often be the only wood someone could find, thus will bring in little more than fruit spurs to place on their rootstock. The only thing worse is when they’d been cut the day before, and are already swelling... But there are generally vegetative, or growth buds near them, so I hunt for at least one of those. At times I’ll ‘warn’ a client not to be scared if ‘it blooms,’ because another bud will likely assume the growth.
…but I’m a bit rusty on my tip-bearers… Maybe a lot more scions are blooming than I’m aware of
