non smell to old fashion lilacs

Question

I am 71 years old and the lilacs in my yard have been here since I was 5 or earlier. I never ever remember them not having that glorious smell.
This year I brought in the flowers for the kitchen table. No smell? I checked out this sight https://www.gardeningknowhow.com/ornamental/shrubs/lilac/lilacs-no-scent.htm
They said cool and damp weather. I cannot believe this out of all the years I have lived here. We do have the farmers elevator in middle of this little town. Just a few blocks from us. We live in Lamoni, Iowa 50140 very tiny town. I am wondering if this has affected them?
It has been a bit cool but we haven’t had that much rain here. The lilacs are healthy and beautiful. Just wondering. I can’t go with that cool and damp here given my period of time with these lilacs.
Thank you.

Answer 1

Yes, cool and damp weather can inhibit the flowering. Give them a bit more time to open fully and develop there fragrance.
You can even cut the flowers and bring indoors, as they warm in the house you will likely get more of the fragrance.
