Japanese cherry blossom trees
Our Japanese cherry blossom trees produce leave but perhaps only one blossom. They were blossoming when we purchased them. Help
Improper pruning can remove blossoms. Pruning should be following blooming.
Cold snaps or temperature drops after buds have formed will kill the buds.
Nitrogen is important but too much nitrogen will inhibit flowering.
Skip fertilizing unless a soil test shows a lack of it.
You can apply some Phosphorous to help promote flowering.
