B-Nine ® WSG (2,500–3,500 ppm) can be used. Drenches of Bonzi ® (3–4 ppm) also work well to control growth and are the preferred method of growth control for Starcluster.

M-V M Tech Tips: Starclusters are slow rooters, so provide sufficient temperature during propagation. They start slow after transplant and need warm temperatures and high light intensities to establish and grow. Cold tempera- tures will lead to long crop times and poor overall quality. Plants will flower faster under relatively long days. Plants will benefit from one to two pinches to improve branching and fill on large pots and patio containers. Bonzi ® drenches work well to control growth.

B-Nine ® (2500–5000 ppm) or Sumagic ® (20–30 ppm) can be used to control growth. A tank-mix spray of Florel ® (350–500 ppm) + B-Nine ® (2500 ppm) can also be used to control growth and improve branching early in production. A Bonzi ® drench (2–3 ppm) can be given 3–4 weeks before finishing.

Temperatures can be lowered three weeks after planting and especially towards the end of production to tone or hold the plant. High DLIs and cool finishing temperatures produce high-quality petunias. Dekko was bred and selected to flower under day lengths of 10.5 hours; however, flower number increases under longer day lengths. Use proper sanitation when pinching or shearing petunia. Petunia and other solanaceous crops are highly susceptible to Tobacco Mosaic Virus (TMV), which can be easily transmitted by mechanical means. L
