LSU AgCenter’s Supertunia Vista Bubblegum is a vigorous petunia with a 3-foot spread at maturity. It can grow 16 to 24 inches tall. Plant these petunias in full sun in well-drained soil. Petunias prefer an acidic soil in the pH range of 5.5 to 6.5. A mulch of pine straw improves the appearance of the landscape bed and minimizes upward splashing of water from irrigation while helping with weed control, while also providing the acidity these petunias love.

When mass-planted in the landscape bed, it is best to plant the petunias on 18-inch centers. This petunia works equally well in containers and hanging baskets where the flowering branches and shoots can cascade over the edge — a truly spectacular “spiller” plant. Always plant the transplants at the original cell pack or pot depth. You mostly see Supertunia Vista Bubblegum for sale in 6-inch pots at garden centers.

There is always confusion about the best time to plant petunias in the landscape. In Louisiana, petunias do well when planted in the fall from September through early November and in late winter and early spring from early February through mid-March. A fall planting of petunias will normally overwinter well and provide blooms until late May. Late winter- and early spring-planted petunias normally last only until early June, but if the weather cooperates, the more heat-tolerant petunias — like Supertunia Vista Bubblegum — can be oversummered successfully.
