Tech Tips: These varieties have medium vigor and usually require regular plant growth regulator (PGR) applications, especially under warm growing conditions. 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 crucial 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 at or above 6.0 to avoid iron/manganese toxicity.

Tech Tips: Rocky Mountain geraniums are vigorous and usually require regular PGR applications, especially under warm growing conditions. 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.

Tech Tips: Tango is relatively compact and should not require repeated PGR applications. 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. Heliotrope SCENTROPIA ™ Heliotropium arborescens 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) 66–68 °F (19–20 °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 Tech Tips: Scentropia has a medium-vigorous habit and typically requires some PGRs to keep plants compact, especially under tight spacing. Late B-Nine ® WSG sprays can delay flowering. Avoid severe drying out of the media. The beautiful purple-blue flowers have a sweet scent.
