Tech Tips: Keep media pH down in the mid 5’s to avoid iron deficiency and tip chlorosis. Temperatures can be lowered three weeks after planting and especially towards the end of production to tone or hold the plant. High DLIs and cool finishing temperatures produce high-quality petunias. Use proper sanitation when pinching or shearing petunia. Petunia and other solanaceous crops are highly susceptible to Tobacco Mosaic Virus (TMV), which can be easily transmitted by mechanical means.

Salvia VELOCITY ™ Salvia farinacea 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 ppp | 9–10 weeks 3 qt. | 3 ppp | 9–10 weeks 1.5 gal. pot | 4 ppp | 10–11 weeks Tech Tips: Velocity Salvia is a fast flowering Salvia farinacea type with beautiful dark blue flowers. One pinch in either propagation or shortly after transplant is all that is needed. Plants fill in quickly once they become established. High light intensity is vital for optimum flowering. Make sure to let media dry down to level 2 between irrigation cycles. Overly wet conditions can lead to fungal root rot.

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. 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
