SEED FINISHING
FINISH PGRs
TECH TIPS
Usually not required if growing cool. If conditions are warmer or darker than ideal spray with B-Nine ® WSG at 2,500–5,000 ppm.
Keep media pH below 5.8 to help avoid Thielaviopsis infections. Under hot temperatures, provide lower light levels to reduce heat stress. If frequent irrigation occurs due to high temperatures, apply a supplemental feed of Solubor ® to avoid boron deficiency.
FINISH PGRs
TECH TIPS
Pinching Arabesque Penstemon will result in more blooms at the finishing stage but will delay flowering by 2–3 weeks.
Sumagic ® at 5–10 ppm or a tank mix of B-Nine ® WSG at 1,500 ppm plus Altercel ® at 750 ppm. Alternatively, drench with Bonzi ® at 0.5–2.0 ppm. One to two applications are generally needed.
FINISH PGRs
TECH TIPS
Provide long days and 68 °F (20 °C) average daily temperature for fastest flowering and finishing.
If grown cool will likely not require plant growth regulator (PGR) applications. However, if needed spray applications of Bonzi ® at 10–15 ppm or Sumagic ® at 5 ppm are effective in controlling stem elongation.
FINISH PGRs
TECH TIPS
B-Nine ® WSG at 2,500–5,000 ppm, Altercel ® at 750–1,000 ppm, Bonzi ® at 5–10 ppm or A-Rest ® at 3–5 ppm.
Use calcium and nitrate-based fertilizers to maintain pH above 6.1 to prevent iron toxicity symptoms. Additional applications of magnesium sulfate at 1 lb. per 100 gallons every three weeks is recommended to help maintain healthy, green color. Warm temperatures and high light levels will accelerate growth and flowering.

VIGOR TIMING MPR
Providing cool temperatures, high light and ‘growing on the dry side’ will help keep Petunias more compact. Early morning DIF treatments also help. Providing long day lighting during short days will shorten time to flower.
B-Nine ® WSG at 2,500–3,500 ppm or Bonzi ® at 5–15 ppm. Bonzi ® drenches are not recommended.
