Do petunias only last one year?
Petunias are perennial, although most bedding types are grown as annuals from seed each year. The trailing varieties, such as Surfinias, are perennial and are grown from cuttings or new plants.
What do you do with petunias when they finish flowering?
Can petunias come back every year?
They can grow perennially only in the warmest corners of the United States (USDA zones 10 and 11). As a result, most gardeners treat petunias (Petunia x hybrida) like annuals and replace them every year.
Can I save my dying petunias?
With quick intervention, petunias can often be revived. Cut back foliage on overly dried petunias to within several inches of the soil level. If foliage remains green, the chances of success are good. If leaves have yellowed, become brittle or begun to turn brown, cutting the petunia back may revive it.
Can petunias handle extreme heat?
Not only are petunias heat tolerant, but their vibrant blooms add just the right amount of color to your yard. One of our favorite petunia series, is 'Petchoa, SuperCals'.
