Cycocel ® (750 ppm), B-Nine ® WSG (2,500 ppm), or Cycocel ® (750 ppm) + B-Nine ® WSG (1,500– 2,500 ppm) can be used depending on the growth rate and vigor of the plant. The Cycocel ® + B-Nine ® WSG combo spray will have a more growth regulating effect than either the Cycocel ® or B-Nine ® WSG spray alone. Sprays of A-Rest ® (2 ppm) or Sumagic ® (0.5 ppm) can also be applied if more growth control is needed.

Tech Tips: Nirvana Cascade vinca requires high light and warm temperatures for high-quality plants. Avoid over-watering and cool temperatures during production. With adequate heat and light, one early pinch is all that is needed to produce well-branched plants. Nirvana Cascades work well in baskets. Avoid excessively cold mist water during propagation, or distorted young foliage can occur. Keep young plants fertilized during propagation to prevent bottom leaf yellowing. Heritage ® or Mural ® sprenches or drenches help prevent fungal Basal Stem Rot after transplant.
