Mature stella cherry didn't flower
I have a mature stella cherry tree (about 3m tall and wide). last year it flowered and produced little green fruits which all fell off. The tree had a really bad pear and cherry slug infestation so I assumed this was why the fruit fell. Over winter we put the chickens under the tree and this year we haven't seen a single pear and cherry slug. But it's supposed to fruit in december in our area and we haven't had any flowers on it yet. does anyone have any ideas about why it's not flowering?
If anyone can offer any insight i'd really appreciate it - i'm a very novice gardener.
