1 qt. | 1 ppp | 8–9 weeks 1.25 qt. | 1 ppp | 10–11 weeks 2.5 qt. | 2 ppp | 12–13 weeks 3 qt. | 3 ppp | 12–13 weeks

Tech Tips: Madinia Maximo Dipladenia 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. 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 (800–1,200 micro mols) Day neutral 76–78 °F (24–26 °C) 70–72 °F (21–22 °C) 200–250 ppm N 1 pinch 1.5 gal. HB | 4 ppp | 10–11 weeks 2 gal. HB | 5 ppp | 10–11 weeks Tech Tips: Mezoo Dorotheanthus 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. Euphorbia EUPHORIC ™ Euphorbia hypericifolia 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 1 qt. | 1 ppp | 6–7 weeks 1.25 qt. | 1 ppp | 8–9 weeks 2.5 qt. | 1–2 ppp | 9–10 weeks 3 qt. | 3 ppp | 9–10 weeks 4,000–6,000 foot candles (800–1,200 micro mols) 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 1.25 qt. | 1 ppp | 8–9 weeks 2.5 qt. | 1 ppp | 9–10 weeks 3 qt. | 2–3 ppp | 9–10 weeks 1.5 gal. HB | 4 ppp | 10–11 weeks 2 gal. HB | 5 ppp | 10–11 weeks

Tech Tips: Stick unrooted cuttings immediately to reduce bottom leaf yellowing and drop that can occur if cuttings are held for too long. Euphorbia is very sensitive to ethylene damage during shipping. Euphoric is a slow starter both in propagation and finish, but grows quickly when established and growing under warm temperatures. High light and warm temperatures will improve plant quality and reduce root diseases. If grown too cold and wet, fungal root can develop. Plants can be trimmed to shape at any point during production. Bonzi ® drenches work well to control growth mid to late in the production cycle. Geranium Interspecific CALDERA ™ Pelargonium interspecific MEDIA pH/EC LIGHT LEVEL DAY LENGTH DAY TEMP NIGHT TEMP FERTILIZER PINCHES FINISHING PROGRAM pH: 5.5–5.9 SME 2.3–2.8 mS/cm, PourThru EC: 3.5–4.2 mS/cm 4,000–6,000 foot candles (800–1,200 micro mols) Day neutral 72–74 °F (22–23 °C) 68–70 °F (20–21 °C) 200–250 ppm N Not recommended 2.5 qt. | 1 ppp | 10–12 weeks 3 qt. | 2–3 ppp | 11–13 weeks Tech Tips: Caldera Interspecific Geranium is vigorous and requires regular plant growth regulator (PGR) applications, especially under warm growing conditions. Provide relatively high light levels and warm temperatures early on to establish the crop. Early Florel ® sprays are key in making well-branched, quality plants. Watch for Botrytis under tight spacing and in combination plantings, especially when overhead irrigating. Monitor the media and try to keep the pH between 5.5–5.9 to avoid iron deficiency (tip chlorosis).

1.5 gal. HB | 3–4 ppp | 11–12 weeks 1.5 gal. pot | 2 ppp | 11–12 weeks 2 gal. HB | 4–5 ppp | 11–12 weeks

Tech Tips: Caliente geraniums are moderately vigorous and usually require regular PGR applications, especially under warm growing conditions. Know the varieties since some are more vigorous than others. Provide relatively high light levels and warm temperatures early on to establish the plant and to allow it to respond adequately to PGRs. Early Florel ® sprays are key to making well-branched, quality plants. Watch for Botrytis under tight spacing and in combination plantings, especially when overhead irrigating. Monitor the media and try to keep the pH around 6.0. Too high of a pH can lead to iron chlorosis and leaf tip yellowing.
