1.5 gal. HB | 4 ppp | 10–11 weeks 1.5 gal. pot | 3–4 ppp | 10–11 weeks 2 gal. HB | 5 ppp | 10–11 weeks Tech Tips: Bombay Scaevolas likes high light and warm temperatures during finishing. Low temperatures, especially early on, can lead to root rot and dark purple foliage. Plants can be pinched twice for baskets and larger containers. Florel ® in finished production can significantly delay flowering and is not recommended. Late B-Nine ® WSG sprays can significantly reduce flower size. Variegated Swedish Ivy PLECTRANTHUS COLEOIDES Plectranthus coleoides 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 short day 70–72 °F (21–22 °C) 64–66 °F (18–19 °C) 125–175 ppm N 1 Pinch 1 pt. | 1 ppp | 4–6 weeks 1 qt. | 1 ppp | 4–6 weeks Tech Tips: To produce a more mounded-shaped plant, a second pinch during production (2 weeks after transplant) can help. To avoid root rots, Botrytis stem blight and edema allow the media to dry to level 2 as the plant matures. This plant serves as more of an accent to other annuals in larger combinations. Time and cooler temperatures will be required to either shape the plant for more of a mounded profile, or warmer temperatures and less pinching and PGRs will create a more trailing habit. Verbena LANAI ® Verbena 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 70–72 °F (21–22 °C) 62–64 °F (17–18 °C) 200–250 ppm N 1-2 Pinches 1 qt. | 1 ppp | 6–7 weeks 1.25 qt. | 2-3 ppp | 6–8 weeks 2.5 qt. | 2–3 ppp | 6–8 weeks

Tech Tips: Transplant liners on time since they can get quickly overgrown and root into other cells when left in plug trays for too long. A Bonzi ® drench applied about 4 weeks before finishing is key to producing compact, mounded baskets and containers. Scout regularly for insects, especially Thrips (which can transmit Tomato Spotted Wilt Virus - TSWV). Don’t let verbenas get extremely dry since this can cause leaf chlorosis, leaf necrosis, and loss (shattering) of flowers. Verbenas can be grown on the cool side to help control growth.
