    • Rooting Hormone: No
    • Average Days with Mist: 6-9
    • Pinch: No
    • Average Propagation Time (weeks): 3-4
    • Average propagation time for perennials includes 3-5 weeks to bulk-up the liner before beginning cold treatment when started in late Summer or early Autumn.

    • Comments: Avoid stretch by moving crop to cooler air temperature in second and third weeks of propagation. Transplant on time.
    • Soil pH: 5.4-5.8
    • Light Levels (fc): 5,000-8,000
    • Temperature Day: 59-76°F (15-24°C)

    • Fertilization (ppm N): 225-300
    • No. of Pinches: 0-1
    • Plant Growth Regulators (S=spray / (D=Drench: B-Nine(S) 1,500-2,500 ppm, applied 2-4 times, can be used to control habit early. Bonzi(D) 0.25-1.0 ppm applied as crop matures will control final height but not delay flowering or reduce flower size.
    • Pests: Whitefly, thrips, leafminers
    • Diseases: Botrytis, Root rot, Tobacco Mosaic Virus
    • Comments: Cool temperatures and high light will reduce or eliminate any need for PGRs. Monitor regularly for high pH and possible iron deficiency. Flowering will be best as days lengthen in late Spring and Summer. Daylength of more than 14 hours will hasten flowering.

We’ve trialed ColorRush in the ground in various climates. Time and time again, it lives up to its name by providing massive mounds of vibrant color. The chart at the right shows the flowering weeks you can expect by region.


West Region

Finish in an outdoor cold frame, where it can receive natural night temperatures as low as 32˚ F (0°C), but have some form of greenhouse roof protection to avoid frost exposure. PGRs in our trials were not needed when average daily temperature was below 54˚ F (12°C) in outdoor tunnels.

Midwest, Canada and Northeast Regions

Based on our Midwest trials, we recommend a Bonzi spray at 5 ppm 10 days after stick and a Bonzi drench at 5 ppm 3 to 4 weeks after transplant, if needed. This keeps plants from growing together on the bench.

South or Southeast Region

Finish in an outdoor cold frame, where it can receive natural night temperatures as low as 32˚F (0°C), but should not be exposed to frost during the production cycle. Since many locations in the South or Southeast will not be able to provide an average daily temperature under 54˚F (12°C), we recommend a Bonzi drench between 1 to 3 ppm to control finished growth.
