Powdery mildew
A common issue on perennial sunflowers, especially in dry soil or crowded plantings. Keep roots moist, space plants, improve airflow and remove affected leaves.
Floppy tall stems
The 1.5 m stems can lean or break, worsened by shade or rich feeding. Stake early, grow in full sun, and avoid over-fertilising.
Spreading clumps
It spreads by rhizomes and can crowd neighbours. Lift and divide every few years to control its spread and maintain vigour.
Sparse flowering
Too little sun or a short, cool summer reduces bloom. Give it the hottest, sunniest position available for the best late-season display.
