SEED FINISHING
FINISH PGRs
TECH TIPS
B-Nine ® WSG at 2,500–5,000 ppm if needed.
Extending the day length during short days to 14 hours will help ensure the first flowers will be fully double. Do not overwater—Zinnias are susceptible to root rot diseases. Growing at lower than recommended temperatures can also lead to root disease issues. Proper air circulation will help reduce the likelihood of powdery mildew infections.
FINISH PGRs
TECH TIPS
Spray with B-Nine ® WSG at 2,500–5,000 ppm 1–3 times depending on container size and environmental conditions. Start plant growth regulator (PGR) applications early—about one week after transplant. To prevent late flower stem stretch drench with Bonzi ® at 1–2 ppm when flowers start to show color.
