    Uses Notes: 

    Superbena are great in landscape beds, but are also wonderful in patio planters and hanging baskets by themselves. They also make a wonderful spiller in combination recipes.

    Maintenance Notes: 

    These are heat tolerant plants, that aren't particularly fussy. They need little routine maintenance. They will perform best if an application of controlled release fertilizer is included at the time of planting. This applies to both landscape and container plantings. The plants aren't particularly heavy feeders, so a single dose is usually sufficient for landscape beds in most climates. If you have a very long season, a second application of controlled release plant food should be considered for landscape beds. In general, containers need to be fed more than landscape plants. A second application of a controlled release fertilizer should be applied about every two months to container plants or you can regularly apply water soluble fertilizer starting about two months after the containers are planted. These extra applications of plant food can really make a difference in performance through the summer.

    If your plant begins to look open or a bit tired, an allover trim can be beneficial.  Use a sharp pair of scissors or pruning shears to trim back up to 1/3 of the volume of the plant. I pair any trim with a dose of water soluble fertilizer to provide instant energy to help kickstart new growth, branching and flowering. Your plant will take a week to recover from the trim, but the end result is a fuller plant with more blooms going forward. You may repeat the trim as needed through the season.
