Beautiful new lilac growth dies... #757524

Asked June 21, 2021, 3:42 PM EDT

Last summer I took my over grown lilacs down by 1/3.  I had beautiful new growth in the spring, many runners.  At this time all of the new growth has died and other branches are also looking sketchy.  Any ideas?

Hello Lynnette

You can compare what signs you see with the list of “pests and problems” of lilac here-

Lilac is also susceptible to verticillium wilt-

A picture of the whole shrub and a close up picture of the wilted part can be emailed to for more ideas. This is the MSU  Plant and Pest Diagnostic lab. They may ask for a sample branch- and instructions, fee schedule, etc for submitting samples are here
