Forsythia Twisted Growth: Herbicide Injury Suspect

Ashley: two forsythia with curly new growth unlike healthy growth. Asks: insect, disease, or treatment?

Expert Assessment

Steve: not insect/disease. Check weed killer/herbicide use nearby (especially if normal last year). Some herbicides cause twisted growth. Photo accepted for confirmation.

Key Insight

Twisted, distorted new growth on multiple plants = classic herbicide symptomology (especially growth regulators). Timing correlation with application history is diagnostic.
