Early Spring through Fall Finish. Standard PPP. Best in 6" and larger pots, except for Superbena Royales and Superbena Sparkling varieties which work great in 4.5" or larger.
For all sizes of containers, pinch the liner 1–2 weeks after transplant; for containers larger than 6” and for hanging baskets, trim around the edge of the container as needed prior to spacing or hanging of the baskets.
Sumagic at 5-10 ppm may be used to keep neighboring pots from growing into each other. Growth can be controlled using lower temperatures. Superbena Royales and Superbena Sparkling varieties will need less PGR manipulation and will be easier for small pot production.
General pest and disease practices as listed in notes. Powdery Mildew can be a problem for verbena. Proper air circulation, humidity control and water management will aid in control and prevention. A broad spectrum fungicide application two after transplanting is highly suggested. Good sanitation practices include keeping greenhouses clean at all times, eliminating weeds and debris, disinfecting equipment in greenhouses as often as possible and keeping hose ends off of the greenhouse floor. Good water management practices are critical for good, healthy plant growth.
-High light in production is essential. -200 ppm fertilizer is optimal -Superbena is our most vigorous series of Verbenas. -Superbena Royale and Superbena Sparkling varieties have more controlled growth and will work more easily in smaller pot sizes as well as filling larger pot sizes. -Superbenas are our most vigorous Verbena series and are our best series in very hot environments. Low pH and severe dry down can cause Iron toxicity if supplemental Iron has been applied. -Superbena Royales and Superbena Sparkling are more compact, with great flower coverage. They will need less PGR manipulation and will be easier in small pot production than other Superbenas.
