Maintenance Notes

Self-cleaning, no deadheading necessary.

Superbena are our most vigorous, heat tolerant, and mildew tolerant series. While always great in containers they are also fantastic in landscape beds. They can tolerate dry soils and lower fertility. Normally either an application of slow release fertilizer or amending with compost is enough to keep them happy and blooming in landscape beds. They shouldn't need to be trimmed back but can be given a "haircut" - a trim back - using a sharp pair of scissors or pruning shears at any time. While naturally well branched, trimming them back will encourage additional branching, fuller plants, and ultimately more flowers. I usually give them a very slight trim as I am transplanting to boost branching.

An application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.

Great for use in both containers of all types and landscapes.

Pinching and Growth Regulators

One pinch at liner planting. Trim back as needed. Sumagic at 5-10 ppm may be used to control growth. Growth can be controlled using lower temperatures.

Pest and Disease Management

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 routine preventative spray program is encouraged. Preventative mildew sprays should be used regularly.
