Use in large combinations, containers and landscapes.

These are heat tolerant petunia plants that aren't particularly fussy and 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. Supertunia Vista Snowdrift are heavy feeders, but 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 plantings. In general, petunia in containers need to be fed more than landscape plants. Supertunia white petunia in containers will need to be fed more regularly to be their absolute best. A second application of a controlled release fertilizer can be applied about every two months to container plants, which will help. However, for the very best performance, I find regularly applying water soluble fertilizer starting about two months after the petunia in containers are planted gives the best results.  These extra applications of plant food really make a difference in performance through the summer, even for heat tolerant petunia plants.

If your white petunia 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 to Supertunia Vista Snowdrift. Your heat tolerant petunia 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.
