Lilac Bushes Not Blooming
I have two established lilac trees that are intertwined to look like one tree. Both trees always bloomed for years. I fertilized in spring and cut the dead flowers. Only one tree bloomed. I also planted a new tree 3 years ago; it's 5' tall doing very well except it has never bloomed. There were lilac flowers everywhere, so it's not the weather. Most trees and bushes were not taken care of. Any suggestions?
