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 plant growth regulators (PGRs) will create a more trailing habit.

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.
