STROBILANTHES CONTINUED OTHER TIPS For proper plant growth and desired finished quality, long days must be provided to plants grown between the months of mid-September and the first of April. In these time periods provide 14-hour daylength through either daylength extension or night interruption lighting. Without proper daylengths these plants will develop blooms on very small and stunted plants. A measure that can be taken to ensure proper growth and encourage branching is to apply Florel (ethephon) at 250ppm two weeks after transplanting and again, if desired, two to three weeks later. Moderate to high light, warm temperatures, adequate spacing, managed moisture levels, slightly higher humidity levels and moderate nutrition levels are all crucial for producing quality crops. Plants should be scheduled and grown in time frames that supply these requirements. In certain areas of the country it is best to schedule Persian Shield for later spring and summer sales. The rates and chemicals listed are based on our southeast Michigan growing conditions, and are not recommended for nationwide application. Please adjust the rates and spray applications to your location and facility. 57
