Until recent years petunias were a risky venture for me. By late summer, the plants would often become unattractive and spindly, or disappear completely – victims of disease and fungus. Then I began noticing glorious drifts of colorful petunias thriving in conditions that ranged from pampered flower borders to harsh mall-scapes. I was somewhat befuddled at my lack of petunia prowess until I visited Pleasant View Gardens where the petunias were standing knee high and covered in blooms. I just had to ask, "What’s the secret to growing petunias?" The answer was in the genetics. These were no ordinary petunias, but a modern cultivar called Supertunia?.
Supertunia? petunias are disease resistant, self-cleaning and floriferous with sturdy stems, which means they remain attractive from spring planting until the first frost in fall. There are about 30 varieties of Supertunia® to choose from. You’ll find colors ranging from white to chartreuse yellow to bright red to deep purple. Double, miniature and veined flower forms are also available. The plants grow upright, yet they also cascade. It’s an interesting combination that reminds me of a tub brimming over with bubbles. Plant Supertunia? petunias in a spot where they will receive full sun. Consistent moisture is also key along with an application of a liquid fertilizer every five to seven days. Petunias are heavy feeders, so this last point is important. In fact, if you are growing them in containers you’ll want to feed them every time you water.
