FINISH PGRs
TECH TIPS
Usually not required if growing cool. If conditions are warmer or darker than ideal spray with B-Nine ® 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. Do not hold Pansy plugs - transplant before plugs get root bound.

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 most growing environments, chemical growth regulation is required to control stem elongation of Arabesque Penstemon. For growth control, use sprays of Sumagic ® at 5-10 ppm or a tank mix of B-Nine ® WSG at 1,500 ppm plus Cycocel ® at 750 ppm. Alternatively, drench with Bonzi ® at 0.5-2.0 ppm. One to two applications are generally needed.
Warm day temperatures can promote soft growth and excessive stem elongation.

Partybells Penstemon, if grown cool will likely not require PGR applications. However, if needed, spray applications of Bonzi ® at 10-15 ppm or Sumagic ® at 5 ppm are effective in controlling stem elongation.

TECH TIPS
BeeBright Pentas are genetically compact, and typically do not require PGR applications. If needed, the following PGRs are effective as sprays: B-Nine ® WSG at 2,500-5,000 ppm, Cycocel ® at 750-1,000 ppm, Bonzi ® at 5-10 ppm, or A-Rest ® at 3-5 ppm.
Provide supplemental lighting when DLI is less than 12 mols/day. Monitor pH and maintain above 6.1, or growth can stall.
