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.

Avoid over-watering and cool temperatures during production. With adequate heat and light, one early pinch is all that is needed to produce well-branched plants. Nirvana Cascade Vinca works well in baskets. Heritage ® or Mural ® sprenches or drenches help prevent fungal basal stem rot after transplant. 1.25 qt. | 1 ppp | 8–9 weeks 2.5 qt. | 1–2 ppp | 9–10 weeks 3 qt. | 2–3 ppp | 9–10 weeks
