Growing & Maintenance Tips
Best grown in average to moist, or wet, soil conditions. Not tolerant of prolonged dry periods. May be beneficial to prune helenium back in late June, to almost half, to encourage more branching and added bloom count for the fall. Divide every 2-3 years to maintain vigour.
