SEED FINISHING
FINISH PGRs
TECH TIPS
If needed sprays of B-Nine ® at 2,500-5,000 ppm or A-Rest ® at 1-3 ppm are effective. Under long day conditions leaves will be larger so more frequent PGR applications may be necessary. Do not apply PGRs once the buds reach 1 cm in diameter (pea size) since this can cause smaller flower and short flower stems.
Under low light conditions provide supplemental HID light if possible; do not extend daylength as this will extend the time to flower. It is critical to allow adequate dry back between irrigations to prevent stunted and distorted growth. Because of this do not mist at night. If germinating on a bench it is best to use a tent system to increase humidity and reduce the frequency of irrigations/misting.

FINISH PGRs
TECH TIPS
A combination spray of B-Nine ® WSG at 2,500 ppm and Cycocel ® at 800 ppm two weeks after transplant is highly effective for reducing height and producing a compact, well-branched plant. In warmer conditions, a second application is beneficial.
If Cycocel ® is applied, seedlings may temporarily yellow. Begin feeding at 75 ppm N at radical emergence.
FINISH PGRs
TECH TIPS
Impatiens are responsive to B-Nine ® WSG, Bonzi ® and Sumagic ® .
Use a calcium based fertilizer and feed once a week at most to avoid soft growth and stretching of plugs. Do not let plants go into the night with wet foliage or tip abortion may occur. Downward cupping or twisting of immature leaves may be caused by overuse of PGRs. Subdue Maxx ® and/or Segway ® drenches are recommended plug stage fungicides for disease management.
