ANNUALS | 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. Malformed and puckered leaves indicate calcium or boron deficiencies. To prevent this, fertilize with plug special (13–2–13) or a Cal-Mag ® Plus fertilizer (14–4–14). Boron deficiencies can be distinguished by tip abortion, upper leaf stunting, puckering and thickening of leaves, along with shortened internodes and/or a gnarled mass of lateral shoots. Boron deficiency is more prevalent during warm weather with frequent watering. A borax or Solubor ® drench will help overcome these problems, as well as increase the airflow within the greenhouse.

TECH TIPS
For packs or small containers, sprays of B-Nine ® WSG at 3,000–5,000 ppm can be effective in controlling vigor. Plant growth regulators (PGRs) may not be necessary for finishing in larger containers unless conditions are not ideal and may lead to stretch.
