Tech Tips: Long-day lighting (daylength extension or night interruption) is needed during propagation to avoid premature flowering and tuber formation. The 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. Karma grows best under moderately warm temperatures. Avoid extreme heat stress, especially under relatively high light intensities. Scout and treat for a range of insects and diseases, including spider mites, thrips, and powdery mildew.

Provide warm temperatures early on in finishing to allow plants to establish after transplant. Sincerity grows best under moderately warm temperatures. Avoid extreme heat stress, especially under relatively high light intensities. 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. Diascia DARLA ® Diascia barberae MEDIA pH/EC LIGHT LEVEL DAY LENGTH DAY TEMP NIGHT TEMP FERTILIZER PINCHES FINISHING PROGRAM pH: 5.8–6.2 SME 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm 4,000–6,000 foot candles Day Neutral 70–72 °F (21–22 °C) 62–64 °F (17–18 °C) 200–250 ppm N 1 Pinch 1 pt. | 1 ppp | 6 weeks 1 qt. | 1 ppp | 6–7 weeks Tech Tips: Avoid dehydration of the cuttings before sticking in propagation. Darla is best when grown cool with high light. No PGR is typically needed when plants are grown cool. One pinch is all that is needed for this crop. Florel ® can be used early but will severely delay flowering if sprayed too late in the crop cycle. Watch for Botrytis in the crown of plants when overhead watering. Dipladenia MADINIA ® Mandevilla hybrida MEDIA pH/EC LIGHT LEVEL DAY LENGTH DAY TEMP NIGHT TEMP FERTILIZER PINCHES FINISHING PROGRAM pH: 5.8–6.2 SME 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm 4,000–6,000 foot candles Facultative Long Day 76–78 °F (24–26 °C) 70–72 °F (21–22 °C) 200–250 ppm N 1 Pinch 1 qt. | 1 ppp | 8–9 weeks Tech Tips: Madinia has a controlled growth habit and bred for improved branching. They make very nice quart products. An early pinch (either in propagation or shortly after transplant) will encourage branching. High light and warm temperatures will improve quality and help reduce crop times. Higher light intensities and longer photoperiods help reduce the natural vining of the plants.

Dorotheanthus MEZOO ™ Dorotheanthus bellidiformis MEDIA pH/EC LIGHT LEVEL DAY LENGTH DAY TEMP NIGHT TEMP FERTILIZER PINCHES FINISHING PROGRAM pH: 5.8–6.2 SME 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm 4,000–6,000 foot candles Day Neutral 76–78 °F (24–26 °C) 70–72 °F (21–22 °C) 200–250 ppm N 1 Pinch 1 qt. | 1 ppp | 6–7 weeks 1.5 gal. HB | 4 ppp | 10–11 weeks 2 gal. HB | 5 ppp | 10–11 weeks Tech Tips: Mezoo is a trailing succulent-type vine that makes beautiful baskets and combo plantings. It is a relatively slow starter and is best grown warm to get it established and growing. Under high light, it will develop small colorful red flowers that add character to the plant. This is a very tough plant that grows and performs under a range of environmental conditions. 1.25 qt. | 1 ppp | 8–9 weeks 2.5 qt. | 1–2 ppp | 9–10 weeks 3 qt. | 3 ppp | 9–10 weeks 1.25 qt. | 1 ppp | 10–11 weeks 2.5 qt. | 2 ppp | 12–13 weeks 3 qt. | 3 ppp | 12–13 weeks
