Lilac bush flowering issue

Zone 4 | keith13 added on June 13, 2012 | Answered

My lilac looks as though it is going to flower nicely in spring. Flower buds form and then turn black and die back. The plant looks fine but no flowers just black buds that look burnt.

It could be a fungus or it may have been thrips. Treat the tree with both a pesticide or a fungicide. I like neem oil myself as it is both a pesticide and a fungicide and is organic.
