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. Also, if very frequent irrigation occurs due to high temperatures, apply a supplemental feed of Solubor ® to avoid Boron deficiency.

TECH TIPS

Under favorable conditions, growing on the dry side will control growth adequately. Fall crops usually require a PGR application due to the warmer temperatures. Sprays of B-Nine ® WSG at 2,500 ppm plus Cycocel ® at 1,000 ppm are effective as are sprays of Bonzi ® at 20 ppm.

It is important to treat with Bonzi ® early in the plug cycle, as stated above to help create a stronger main stem.

TECH TIPS

Spray with B-Nine ® at 2,500–5,000 ppm 1–3 times depending on container size and environmental con- ditions. Start 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.

Transplant Zinnias on time. Stress in the plug can lead to premature flowering.
