Here’s a description of the garden issue I found:<\/h5>\n\n\n\n


I have three lilac trees at least 6 years olds. I moved into the house three years ago. The trees are in the South part of the garden getting full sun. They are at least one foot apart.\u00a0 They line the driveway to the garage. They get water regularly especially on hot days. They get fertilizer\u00a0at least 1-2 times before blooming. They get compost dressing once a year and mulch in the late fall.\u00a0 Last year and more this year, all three trees have few and puny blossoms which turn brown in a couple of days. About 60% of the leaves are brownish, curling or have spots. The branches are semi-bare except for leaves near the end. The tips of the many branches are black, almost burnt looking.\u00a0<\/p>\n\n\n\n


I’m including photos that show the issue.<\/h5>\n\n\n\n

And here’s what I think is going on<\/h5>\n\n\n\n

My Lilacs have\u00a0Lilac Bacterial blight<\/a><\/u><\/strong><\/p>\n\n\n\n

I conclude that it is blight based on the symptoms I described and on the pictures I posted compared to the resource:<\/p>\n\n\n\n
