FINISH PGRs
TECH TIPS
Spray with B-Nine ® WSG ® at 2,500–5,000 ppm as needed.
Verbena is very attractive to thrips and they can infect the plants with Tospovirus (Tomato Spotted Wilt Virus or Impatiens Necrotic Spot Virus) so start with an effective scouting program and start a thrips control program as soon as any population is detected. Supplemental HID lighting under short days or during cloudy weather will hasten flowering.
FINISH PGRs
TECH TIPS
Drench with Bonzi ® at 1–3 ppm as needed to control growth. Also responds to sprays of Bonzi ® at 10–20 ppm or B-Nine ® WSG at 3,500–5,000 ppm.
Verbena is very attractive to Thrips and they can infect the plants with Tospovirus (Tomato Spotted Wilt Virus or Impatiens Necrotic Spot Virus) so start with an effective scouting program and start a thrips control program as soon as any population is detected. Supplemental HID lighting under short days or during cloudy weather will hasten flowering. Pinching Obsession Cascade Verbena will create the fullest looking plant but will increase crop time by about ten days.

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.
