SEED FINISHING
FINISH PGRs
TECH TIPS
B-Nine ® WSG at 2,500–5,000 ppm if needed.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.1. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
Plant growth regulator (PGRs) are not usually necessary. If needed spray with B-Nine ® WSG at 2,500–5,000 ppm.
To avoid iron and/or manganese toxicity, monitor and maintain media pH above 6.1. If plugs are stretched, plant them deep, up to the cotyledon, to prevent floppiness.
FINISH PGRs
TECH TIPS
If needed to control height, spray with B-Nine ® WSG at 2,500–5,000 ppm, Bonzi ® at 15–30 ppm, or Sumagic ® at 5–10 ppm. To help control growth in the retail environment, drench with Bonzi ® at 2–5 ppm or Sumagic ® at 1–2 ppm when plants are up to size and flowering.
If plugs are stretched, plant them deep (up to the cotyledons is ok) to prevent floppiness. Maintain soil pH above 6.1 to avoid iron and/or manganese toxicity.
FINISH PGRs
TECH TIPS
Under proper growing conditions, plant growth regulators (PGRs) are usually not needed. If warm and/or dark conditions exist, sprays of B-Nine ® WSG at 2,500 ppm are effective.
If plugs were provided 14 hour days, then day extension lighting isn’t required after transplant. Growing Magic Mimulus in cool conditions will give the best quality plants. Control thrips to reduce the chance of INSV infections.
FINISH PGRs
TECH TIPS
If needed to control height, spray with B-Nine ® WSG at 2,500–5,000 ppm, A-Rest ® at 3–7 ppm, Bonzi ® at 10–30 ppm, or Sumagic ® at 5–10 ppm.
Under low light conditions supplemental light at 300–400 foot candles (60–80 micro mols) will induce earlier flowering. An overapplication of Bonzi ® can cause the foliage to crinkle.

B-Nine ® at 2,500–5,000 ppm or Cycocel ® at 750–1,000 ppm as needed
Do not apply plant growth regulators (PGRs) after buds have set to avoid reduction in flower size. Asti Osteospermum does not require vernalization to flower but will have the highest bud count grown under high light coupled with cool temperatures.
