Helenium 'Sahin's Early Flowerer' problems — and how to fix them
Helenium 'Sahin's Early Flowerer' (Helenium 'Sahin's Early Flowerer') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Common in dry soils combined with warm, humid air. Improve soil moisture retention and ensure good air circulation between plants.
Stem flop
Tall stems may need support in exposed positions. Chelsea chop (cutting back by one-third in late May) reduces height and staking need.
Aphids
Young shoots can attract aphid colonies in spring. Knock off with a jet of water or apply insecticidal soap.
Leaf scorch
Dry soil causes browning of lower leaves. Consistent moisture and a mulch layer prevents this.
Clump congestion
After 3-4 years, central clumps deteriorate. Divide in spring, discarding the exhausted centre and replanting vigorous outer portions.
