Think it says Gisella 5 on the old tag
Must be at least 4 years old and for the last 2 years since I have had it it has not grown and produced only 2 cherries each year
2 years ago I turned it 90 degrees as it was potentially going to grow into a fence
Thoughts please Friends
needs to propped up and most likely pruned .Is a ornamental ? as they do not fruit.sounds like it needed to be planted deeper .
There is a Gisela 5 rootstock which your tree could be grafted on to? should produce a manageable tree about 3M tall.
Are the buds/flowers getting frost damaged in the Spring? Are you feeding the tree with a high potash feed to encourage flowers and therefore fruit?
If its becoming unmanageable prune when in full leaf as Winter pruning can encourage Silver Leaf disease.
