Not required.
Pests & Diseases:
Aphids, leafminers, thrips and whiteflies are the most common pests. The most common diseases of false sunflower are leaf spots (Ascochyta, Cercospora, Phyllosticta and Septoria), rust and powdery mildew.
Potting & Timing:
Plant only in warmer conditions. Cool conditions will cause growth to stall out.
Bare root provides a fuller looking plant and is good for larger containers such as premium 1 gallon or 2 gallon sizes. Plugs work well for trade gallon containers.
Moisture:
Moderate moisture.
Planting Level:
Plant crown even with soil line.
PGRs/Pinching:
Pinch plants 2 weeks after transplanting to increase lateral branching.
Apply daminozide (B-Nine or Dazide) at 2,500 ppm if needed shortly after pinching. Uniconazole (Sumagic/Concise) is also effective at controlling elongation, at rates of 5-10 ppm.
Lighting:
Heliopsis require high light levels and long days to flower.
Grower Tips:
Our recommended planting option is bare root as it yields a fuller looking plant in a short amount of time.
