SEED FINISHING

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.

FINISH PGRs

TECH TIPS

Usually not required in larger containers. In small pots/packs or under low light conditions spray with Bonzi ® at 1-3 ppm as needed.

Ensure a good scouting program for Thrips is in place.

FINISH PGRs

TECH TIPS

Usually not required, especially when finished during short days. If necessary under low light or high temperature/humidity conditions spray with B-Nine ® at 5,000 ppm before buds are wider than 1 cm (pea size). Later PGR sprays may reduce flower size or cause flowering in the foliage.

Easy to germinate on the bench. Maintain media pH above 6.2 to avoid iron/manganese toxicity. Short days will shorten time to flower.
