Treating Fungal Leaf Spots on Blueberry Flax

Broad-Spectrum Fungicide Works

Brown spots spreading on blueberry flax (Dianella spp.) indicate a fungal infection. Daconil (chlorothalonil) or any broad-spectrum fungicide applied per label, repeated in one week, will stop the spread.

What to Expect

• Old spotted leaves stay stained and may drop.
• New growth emerges clean if treatment is timely.
• Monitor new leaves for recurrence.

Prevention

Improve air circulation, avoid overhead watering, and remove fallen debris. Fungal spores splash from soil; mulch helps reduce splash.
