Tech Tips: Keep the pH down in the mid 5.0s to avoid tip yellowing—drench with iron chelate if necessary. Avoid overwatering of young plants. Plants can be pinched twice on baskets and larger containers (once in prop, once after transplant). An early Florel ® or Florel ® + B-Nine ® WSG spray improves branching. Mid-season Bonzi ® drenches are the key to beautiful mounded baskets. Watch for aphids. High DLIs and moderate-to-cool finishing temperatures produce high-quality plants. Use proper sanitation when pinching or shearing Calibrachoa to prevent possible virus spread.

Tech Tips: Nirvana ® XDR 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 ® XDRs work well in baskets. Heritage ® or Mural ® sprenches or drenches help prevent fungal basal stem rot after transplant. Dahlia hybrida Dahlia CUT FLOWER COLLECTION, KARMA MEDIA pH/EC LIGHT LEVEL DAY LENGTH DAY TEMP NIGHT TEMP FERTILIZER PINCHES FINISHING PROGRAM N/A 1,600–2,000 µmol·m -2 ·s -1 Facultative short day 70–72 °F (21–22 °C) 66–68 °F (19–20 °C) 200–250 ppm N 1 pinch Transplant into field or raised beds.
Tech Tips: Most cut flower dahlias, but especially Café Au Lait, will start to produce semi-double and single flower forms as the day lengths get shorter and cooler into the fall season. Café Au Lait will also be more prone to produce semi-double or single flowers when under various forms of stress from heat or suboptimal irrigation and nutrition during establishment. Nutrition should be maintained through vegetative bulking and flowering in order to support production of fully double flowers longer. If plants are a light green or yellow tone they should be fertilized until tone improves to a healthy, green tone.
