Tech Tips: Sprays of B-Nine WSG ® at 2,500 ppm can be utilized to control growth and provide an alternative to a manual pinch. A Bonzi ® drench can also be utilized starting at 0.5–2.0 ppm with various environmental factors taken in to account. Dahlia CUT FLOWER COLLECTION, KARMA Dahlia hybrida 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.

Tech Tips: Long-day lighting (day length extension or night interruption) is needed during propagation to avoid premature flowering and tuber formation. Ideal photoperiod during finishing to provide the correct balance between vegetative growth and flower formation is between 13–14 hours. Growing under very short natural days (< 12 hours) will result in short plants, fast flowering, and root tubers. Provide warm temperatures early on in finishing to allow plants to establish after transplant. Plant the rooting cutting relatively deep to provide good support and balance in the pot for the maturing plants. Scout and treat for a range of insects and diseases, including Spider mites, Thrips, and Powdery mildew.
