laburnam tree

Question

Hello! I’ve got a 20 year-old laburnam tree in the garden and up until last year it was a prolific flowerer. But last year, about a third of the tree, all on one side, didn’t bloom at all and actually looked like it was dead. The rest of the tree bloomed as it usually did. But this year, the third that last year looked dead is fully bloomed and the rest of the tree has only got a few bblooms – 3 to be exact! Have you any idea what might be causing this behaviour and is it actually a problem? Many thanks for your help.
